TROUBLE DIAGNOSES FOR SYMPTOMS

TCM Self-diagnosis Does Not ActivateECS00EBY
SYMPTOM:
O/D OFF indicator lamp does not come on in TCM self-diagnostic procedure even if the lamp circuit is
good.
DESCRIPTION

PNP switch
The PNP switch assembly includes a transmission position
switch. The transmission position switch detects the selector
lever position and sends a signal to the TCM.

Overdrive control switch
Detects the overdrive control switch position (ON or OFF) and
sends a signal to the TCM.

Closed throttle position signal and wide open throttle position
signal
ECM judges throttle opening based on a signal from accelerator
pedal position sensor, and sends the signal via CAN communi-
cation to TCM.
