THEFT DETERRENT / KEYLESS ENTRY: SMART KEY SYSTEM (for Start Function): U0100: Lost Communication with ECM / PCM "A"

DTC U0100 - Lost Communication with ECM / PCM "A"

DESCRIPTION

The power management control ECU receives shift position information from 2 sources. It receives a shift position P signal from the shift lock control unit assembly via a direct line, and shift position information from the ECM via CAN. If the information from these 2 sources is inconsistent, this DTC will be stored.





WIRING DIAGRAM

Refer to CAN communication system CAN Communication System.

INSPECTION PROCEDURE
NOTICE: When the power management control ECU is replaced with a new one and the cable from the negative (-) battery terminal is connected, the power source mode becomes the on (IG) mode. When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.

Refer to CAN communication system How to Proceed With Troubleshooting.
