Procedure
Please follow your dealership’s safety procedures and precautions to ensure the vehicle can be safely repaired and maintained.
If wiring diagrams are required to locate and identify the connectors, search for the following in WebECAT to identify the harness diagrams:
1. Ensure wheels are chocked and there is ample room in front of and behind the chassis in case the engine starts in gear.
2. Set the park brake.
3. Make sure service brake is applied.
WARNING!
To help avoid injury or property damage caused by sudden and unexpected vehicle movement do not start a Starter Interrupt Circuit test until you:
Put the transmission in N (Neutral)…and Apply the parking brake and service brake… and
Chock the vehicle wheels and take any other steps necessary to keep the vehicle from moving…and
Warn personnel to keep clear of the vehicle and its path.
If the starter engages or the engine starts, the vehicle may move and could result in equipment damage, severe injury, or death.
WARNING!
Use an observer when checking engagement of the starter to make sure there is no one around the vehicle. You will be attempting to start the vehicle in gear during this procedure. You must ensure there is ample room to stop the vehicle if the engine starts. If the starter engages or the engine starts, the vehicle may move and could result in equipment damage, severe injury, or death.
4. Check to make sure the truck starts in neutral and make sure it fully builds air then turn off truck.
5. Attempt to engage the starter in drive or reverse:
a. Turn key to the on position and wait for the electrical system to “wake” up.
b. Place the transmission gear selector in drive.
c. While listening for the starter to engage, turn the key to the start position did the starter engage?
-
- If the starter engages, STOP and continue to Step 6.
-
- If the starter does not engage, place shift controller in reverse and repeat the process. Next place the shift controller in neutral and the engine should start. Repeat this procedure one more time to check safe operation of starter interrupt. If the starter does not engage during these attempts, then no further action is required.
6. Locate the starter interrupt connectors J11/P14 located on the Allison Transmission harness, It is likely to be found routed forward towards rear left of the engine along the firewall, rather than to the rear.
7. Locate the Front Chassis starter interrupt connectors J004/P004.
8. Reroute the portion of the Allison harness containing connectors J11 and P14 so they can reach the Front Chassis harness connectors.
9. Connect J004 to P14 and P004 to J11.
10. Secure the harness with cable ties every 6 inches. Ensure the harness route will not cause chaffing or interfere with moving components.
11. Retest the neutral start circuit as instructed in Steps 1-5 to confirm correct operation of the circuit.
