Chronology of Defect / Noncompliance Determination 573.6 (c) (6) (7)
Describe the chronology of events leading up to the defect decision or test data for the noncompliance decision: (2000)
On July 26, 2021, Isuzu Motors Limited (IML) began production in Japan of interim 2022MY N-Series Diesel vehicles, which, unlike the earlier 2022 MY vehicles (produced between January 2021 to July 2021), were equipped with ESC as standard equipment, and optionally equipped with new ADAS technology. ESC is standard equipment on all subject vehicles and later model year N-Series Diesel vehicles. [ESC – Electronic Stability Control; ABS – Antilock Braking System; ADAS – Advanced Driver Assistance Systems]
In September 2021, the interim 2022 MY trucks equipped with ESC and in some cases the new ADAS technology began to ship to dealers, body builders and, in rare instances, customers from US ports.
On August 23, 2022, Isuzu Commercial Truck of America, Inc. (ICTA) received a question from an independent upfitter who was engaging in a frame modification (wheelbase extension) about whether the ADAS camera needed to be recalibrated.
Between August 23 and September 6, 2022, various engineering and product planning groups within Isuzu began looking into the issue – in connection with the Isuzu factory option to have the frames of the subject vehicles extended from a wheelbase of 176 inches to 200 or 212 inches whether those extended vehicles needed to have the ADAS recalibrated.
On September 6, 2022, Isuzu North America Corporation (INAC) QA and IML launched an investigation. This investigation involved an initial detailed study and then in-depth vehicle testing, which confirmed in late December that the ADAS and ESC systems in the subject vehicles whose frames were extended from wheelbase 176 inches to 200 or 212 inches could be affected by a lack of recalibration.
In the first week of January 2023, INAC received confirmation from IML that a recalibration is required for both the ADAS camera and the ABS module as it affects ESC for all interim 2022MY and 2023MY N-Series Diesel trucks receiving the wheelbase extension from 176 inches to 200 or 212 inches. The potential effect on ESC-equipped and ADAS-equipped vehicles receiving a wheelbase modification from and to a different length (which would be from an independent upfitter, not part of Isuzu’s program) is still under investigation.
On January 10, 2023, based on the above results, INAC QA travelled to both frame modification facilities that carry out the “factory option” frame extensions on behalf of Isuzu and trained the staff so all modified trucks produced after 1/10/2023 have the ADAS and ESC systems properly calibrated.
On January 13, 2023, Isuzu made a determination to conduct a safety recall to address this issue in the affected vehicles in the field.
Isuzu has received no warranty claims related to this issue and is not aware of any crashes or injuries associated with this issue.

Stereo Camera Programming
The following procedure was intended to be performed indoors. If your circumstances do not allow you to program the Stereo Camera Programming indoors,
an alternative, outdoor procedure is available. However, this indoor procedure is preferable.
This procedure will instruct you how to program the ADAS Stereo Camera by establishing the centerline of the vehicle, determining the amount of offset of the
Stereo Camera, properly positioning the Stereo Camera Target parallel to the front of the vehicle, and completing the procedure by entering three
measurements taken during the procedure into IDSS.
Carefully read the following procedure before performing it. Then, perform all the steps in order and exactly as written.
Important:
• The scan tool used for this procedure must be the same from start to finish. If the scan tool is changed midway, the procedure
will fail.
• Do NOT touch the camera lenses.
• The vehicle should be unloaded (no cargo) and no one should be in the vehicle while performing this procedure. Use IDSS from
outside the driver’s door.
• Use masking tape on the floor to mark on to avoid permanently marking the floor.
• Be sure the tires installed on the vehicle are all the same size and meet the original manufactured specification. Tire sizes other
than the OEM specification may cause the ADAS system to not function properly. Do not program the ADAS Stereo Camera until the correct tires
are installed on the vehicle.
• Due to the time requirements of programming, it is recommended that an external power source be used to maintain system
voltage. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming.
To ensure trouble-free programming, it is recommended to use one of the following external power sources:
o A Midtronic PCS charger
o A fully charged 12V jumper or booster pack disconnected from the AC voltage supply
Special Tools and Supplies
• J-53207 Laser Measuring Tool
• J-53325 Cross-line Laser Level
• GE-53292 Plumb Bob/ Twisted Link Set (2 included)
• GE-53206 Stereo Camera Target
• GE-53291 Target Stand
NOTE: All measurements taken and input in this procedure MUST be in metric units (e.g., millimeters).
1. Ensure the Vehicle is not loaded. Position the vehicle on a flat, even, hard, and level surface. Ensure that there is at least 8.0 Meters (26.5
feet) of flat, even, hard, and level surface directly in front of the vehicle. This area must be clear of all objects (shop equipment, poles, other
vehicles, etc.) at least 2 meters (6.5 feet) from each side of the centerline of the front of the vehicle. (See Figure 1.) Ensure the parking brake
is set.
2. Ensure that the windshield is clean, and the wheels are straight ahead.
3. Ensure that the tire size is correct for the vehicle and the tire pressure on all tires has been adjusted to proper specifications.

about:blank 1/19/2023
12. When completed there should be 2 Xs under the vehicle as shown labeled A and B in Figure 10.
13. Remove both Plumb Bobs from the frame holes.
PLUMB BOB STRING SET UP
14. If not already completed per the special tool instructions, make two overhand loops in one of the Plumb Bob strings as shown in Figure
11. The overall length from loop to loop when stretched taut should be approximately 54cm.
KBTree Page 6 of 21
about:blank 1/19/2023
ESTABLISHING CENTERLINE OF VEHICLE
Important: when performing Steps 15 – 20, it is critical that the looped string be held taut. Also, the exact position of the loops on the marker pen
and the Plumb Bob point must be kept the same for each Step. Finally, both the Plumb Bob point and the marker pen should be kept completely
straight up while performing each Step.
NOTE: When performing Steps 15 – 20, refer to Figure 12.
15. Using the Plumb Bob weight point, hold one of the loops steadily on Point (A) made on the passenger’s side of the vehicle. Place the
capped marker pen into the other loop and put the string taut. Pull the taut string towards to the rear-center of the vehicle to make an
estimation of where the masking tape should be for marking the floor and put down a piece of masking tape. (See Figure 12.)
16. Perform Step 15 again, but with the marker pen uncapped, to create about a 3-inch arc on the masking tape at Point (C). (See Figure
13.)
KBTree Page 7 of 21
about:blank 1/19/2023
17. Perform Steps 15 and 16 towards the front-center of the vehicle to create a marked arc on the floor at Point (D). (See Figure 12.)
18. Place the point of the Plumb Bob weight into one loop with the point lightly pressed down directly on the center of Point (B) made on the
driver’s side of the vehicle. Place the capped marker pen into the other loop and pull the string taut. Pull the taut string towards to the rearcenter
of the vehicle to determine if more masking tape is needed on the floor. Lay down more masking tape as necessary. (See Figure 12.)
19. Perform Step 18 again, but with the marker pen uncapped, to create about crossed arc at Point (C) on the floor. (See Figure 12.)
20. Perform Steps 18 and 19 towards the front-center of the vehicle to create a crossed arc at Point (D) on the floor. (See Figure 12.)
21. From about three feet in front of the vehicle use the Cross-Line Laser Level (Special Tool J-53325) to establish the centerline of the
vehicle by placing the tool on the floor, turning it on, and aiming the beam directly through the intersection of both points C and D. (See
Figure 14.)
NOTE: Ensure that enough room is left from the front of the bumper to the Cross-Line Laser Level to allow for about a 12-inch strip of masking tape
laid on the floor lengthwise with the vehicle.
NOTE: When performing Steps 21 – 22, refer to Figure 14.
22. With the Cross-Line Laser Level still in place, put down a 12-inch piece of masking tape lengthwise under the laser beam directly in front
KBTree Page 8 of 21
about:blank 1/19/2023
of the Cross-Line Laser Level. Trace the laser beam line onto the piece of masking tape with a marker pen. (See Figure 14.) This is the
Center of the Vehicle reference mark.
Establish Camera Offset
NOTE: For Steps 23 – 29, refer to Figure 15 as a reference.
23. With the Cross-Line Laser Level still in place, lay an approximately 16” strip of masking tape horizontally on the windshield about 4 inches
above the stereo camera. (See Figure 16.)
24. Use a piece of cardboard angled above the masking tape to reflect the laser beam as shown in Figure 17. Use the laser light to mark the
center of the vehicle on the masking tape with two dots above each other. Use a ruler to connect the dots into a straight line with a ball point
pen. (See Figure 18.) Label this line as the centerline of the truck (C.T.).
KBTree Page 9 of 21
about:blank 1/19/2023
25. Use the mount for the Cross-Line Laser Level to attach it to the end of the Target Stand (Special Tool GE-53291) as shown in Figures 19
and 20. Which way the laser will have to be mounted depends on how high the Stereo Camera is mounted on the vehicle you are servicing.
NOTE: Adjust the Cross-Line Laser Level height as close as possible to the center of the left (passenger) Stereo Camera lens. If the laser beams
flash at any point during Steps 26 and 27, the Cross-Line Laser Level MUST be adjusted so that the angle and height of the horizontal laser beam is
more level with the Stereo Camera lens.
26. Point the Cross-Line Laser Level at the passenger side Stereo Camera lens and adjust the Laser until the passenger side lens is
bisected vertically and horizontally. (See Figure 21.)
KBTree Page 10 of 21
about:blank 1/19/2023
27. Trace the vertical laser beam over the center of the passenger side lens onto the strip of masking tape over the camera with a ball point
pen. (See Figure 15.) Mark this line as the center of the lens (C.L.).
28. Keeping the ruler or tape measure parallel with the floor, measure 80mm towards the driver’s side from the center of the lens line and

Description of the Defect : When the subject vehicles were modified to extend the frame to a 200 inch or 212 inch wheelbase, the ADAS camera and ABS module were not recalibrated to account for the different inputs from the vehicle resulting from the stretched frame. Therefore, when driving in a curve certain ADAS features and the ESC system working together with the ABS module may not function properly.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : If the ADAS camera and ABS module are not recalibrated after the frame is
stretched, one or more of the following events could occur – in each case, increasing the risk of a crash:
• Automatic Emergency Braking System (AEBS) activation (as well as the AEBS warning light) may be delayed when driving in a curve and therefore the AEBS may then decelerate the vehicle more aggressively when activated.
• Adaptive Cruise Control may reduce following distance by about 8-10 m when driving in a curve.
• ESC may activate in an understeer condition without illuminating brake lights.
• ESC may delay activation in an oversteer condition, increasing potential for an oversteer event to occur.
Description of the Cause : The ADAS camera and ABS module were not recalibrated after the frame was stretched. Identification of Any Warning NR
that can Occur : Involved Components : Component Name 1 : Electronic Hydraulic Control Unit (EHCU)
Component Description : Base component for controlling the hydraulic service brakes. Anti-lock Brake System, Electronic Stability Control, Automatic Emergency Braking.
Component Part Number : 8976513901, 8978299390 Component Name 2 : ADAS Stereo Camera

Description of Remedy :
Description of Remedy Program : Isuzu dealers will recalibrate (1) the ADAS camera to account for the
(extended) length of the vehicles, and (2) the ABS module so the ESC system will function properly with the affected vehicles’ longer wheelbases. All subject vehicles are covered under the New Truck Warranty. There is no expectation that these vehicles will need to be remedied outside of the warranty period. How Remedy Component Differs from Recalled Component :
Identify How/When Recall Condition was Corrected in Production : Physically there is no difference, this is a recalibration of the ABS module and ADAS camera.
On January 10, 2023, INAC QA travelled to the frame modification facilities that carry out the “factory option” frame extensions on behalf of Isuzu and trained the staff so all modified trucks produced after 1/10/2023 have the ADAS cameras and ESC systems properly calibrated. Recall Schedule :
Description of Recall Schedule : Isuzu, Chevrolet, and Hino will notify their respective vehicle owners and
dealers of this recall. Customers will be informed that the recall repairs will be done free of charge. The recall owner notification is expected to begin 3/10/2023. For additional information, Isuzu owners may contact Isuzu Customer Relations at 1-866-441-9638, Chevrolet owners may contact the GM Medium Duty Truck assistance line at 1-800-862-4389, and Hino owners may contact Hino Customer Service at 1-248-699-9390.
