November 17, 2020 NHTSA CAMPAIGN NUMBER: 20V711000
Water may get into the BIM/BIR and create electrical arcing, increasing the risk of a fire.
NHTSA Campaign Number: 20V711
Manufacturer Thor Motor Coach
Components ELECTRICAL SYSTEM
Potential Number of Units Affected 1,074
Summary
Thor Motor Coach (TMC) is recalling certain 2020-2021 Daybreak, Four Winds, Chateau, Freedom Elite, Quantum motorhomes built on a Chevrolet
chassis. The BIM (Battery Isolation Manager)/BIR (Battery Isolation Relay) is not watertight when exposed to engine compartment heat.
Remedy
TMC will notify owners, and dealers will replace the BIM/BIR with a Trombetta solenoid, free of charge. The recall began January 13, 2021. Owners may contact TMC customer service at 1-877-855-2867. TMC’s number for this recall is RC000206.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
Issue:
It has been discovered that on certain model year 2020/2021 Chateau, Daybreak, Four Winds, Freedom Elite, and Quantum Motorhomes built on a Chevy chassis, expansion and contraction of the plastic body of the BIM (battery Isolation Manager)/BIR (Battery Isolation Relay) from heat in the engine compartment causes it to be susceptible to moisture inside the body, which in turn produces arcing of the internal components. This internal arcing can cause heating, or the possibility of a fire.
Shop Supplies Needed:
(3) ¼” self tapping screw
(4) #8 self tapping pan head screws
(1) ¼” star washer
Tools Required:
½” socket for torque wrench (for battery cables)
3/8” screw gun bit (for ¼” self tapping screws)
5/16” socket (to remove overflow bottle)
Electrical Tape
Screw Gun
Square head screw gun bit (for #8 self tapping screws)
Wire Crimpers
YouTube Video Instructions Found Here:
Disclaimer– Video is for installation of recall repair on a Ford Chassis. Steps will vary for Chevy Chassis.
Instructions:
1. Disconnect battery cable on the negative post of the house battery located in the step well.
2. Disconnect battery cable from negative post of the chassis battery located under the hood.
3. Locate BIM/BIR mounted on passenger’s side inside fender.
4. Remove the chassis battery cable and the house battery cable from the BIM/BIR and remove BIM/BIR.
Note: The BIM/BIR needs to be returned to Thor Motor Coach for payment of the recall repairs.
5. Remove the screws holding the BIM/BIR to the inside fender.
6. Remove ground wire
7. Open the loom for the dash switch, locate the white and white with black tracer. Cut both wires.
8. Open the loom for the ignition power, locate the yellow wire and cut.
9. Find a good clearance where BIM/BIR was installed to mount the Trombetta solenoid. Make sure it is far away enough from the solenoid installed on fender below where the BIM/BIR was installed to avoid sparking.
10. Start a ¼” self-tapping hex head screw at the installation mark on the fender wall. Slide Trombetta solenoid bracket into place on the self-tapping hex head screw and secure.
11. Install a ¼” self-tapping hex head on the other side of the bracket of the Trombetta solenoid.
12. Install ground wire, black wire with ring terminal, above Trombetta solenoid on the inside of the fender by using a ¼” self-tapping hex head using a 3/8” bit. NOTE: Must use a star washer between the ring terminal and fender.
13. Mount the Isolater Relay Delay (IRD) beside the Trombetta solenoid and along the seam of the fender with 1-2 – #8 self-tapping pan head screws.
14. Verify which cable is coming from the chassis battery by tracing is back to the chassis battery. Remove the washer and nut from the Trombetta solenoid and secure the chassis battery cable to the large terminal post of the Trombetta solenoid closest to the firewall with the washer and nut.
Note: If either battery cable ring terminal is bent –– straighten before securing.
15. Secure the house battery cable to the other large terminal post (towards the front) of the Trombetta solenoid – this house battery is to be secured together with the white wire of the emergency start switch. Put the battery cable on the post first, then place the white wire on top and secure with washer and nut.
16. Tighten nuts on both battery cables using a torque wrench to 45 inch lbs.
17. Locate and cut yellow ignition power wire, strip back, and connect to yellow wire w/ yellow butt connector from the fuse holder. Crimp and heat shrink using a torch or electric heat gun. Using electrical tape, tape both ends of the yellow wires.
18. Locate cut white wire and white with black tracer from the emergency start switch and strip back both wires. Connect white wires with white butt connector and white with black wires white with black butt connector. Crimp both wires and heat shrink.
Use electrical tape to tape both ends of the wires.
19. Zip tie fuse holders and wires together as shown below to keep secure.
20. Reconnect house battery cable in the step well.
21. Reconnect chassis battery cable under the hood.
22. Test the emergency start switch by pushing the switch and listen for an audible clicking noise. This indicates the connection is proper. If you do not hear the clicking noise, check fuse holder and wire connections (white & white with black wires).
23. Start the engine, after 15-20 seconds, you should hear an audible clicking noise. This indicates the connection is proper. If you do not hear the clicking noise, check fuse holder and yellow wire connections.
