Steering - Multiple VSA/VTM-4 and PGM-FI DTC's

TITLE: Multiple VSA, VTM-4, and PGM-FI DTC's

APPLIES TO: 05 Odyssey/Pilot

SERVICE TIP:

Got a '05 Odyssey or '05 Pilot EX-L in your shop with any or all of these symptoms?

- One or more of these VSA DTCs are set:
- DTC 25 (yaw rate sensor)
- DTC 27 (steering angle sensor)
- DTC 51 (motor lock)
- DTC 53 (motor stuck ON)
- DTC 81 [central processing unit (CPU)]
- DTC 86 (F-CAN communication)

OR

- The VSA indicator is lit but no VSA DTCs are set.

- Pilot only: VTM-4 DTC 41-2 (CAN communication) is set.

- One or more of these PGM-FI DTCs are set:
- DTC U0073 [F-CAN malfunction (BUS-OFF)]
- DTC U0144 [F-CAN malfunction (VTM-4 control unit - PCM)]
- DTC U0122 [F-CAN malfunction (VSA - PCM)]

A poor ground G302 is the likely culprit. If this ground is loose or it's not making good contact because there's paint or debris under the terminal, you can wind up with an intermittent or complete loss of communication between the PCM, the VSA control unit, and in Pilot EX-Ls, the VTM-4 control unit. Make sure the terminal is clean and tight. If it
already is, then refer to the appropriate DTC troubleshooting.
