Lost Communication with ECM / PCM "A"
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 the CAN communication system See: U0100.
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 the CAN communication system See: U0100.
