21. TCM Self-diagnosis Does Not Activate (PNP & Overdrive Control Switches,
and Throttle Position Sensor Circuit Checks)
ECS004VM
SYMPTOM:
O/D OFF indicator lamp does not come on in TCM self-diagnostic procedure even if the lamp circuit is
good.
DESCRIPTION
lPNP 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.
lOverdrive control switch
Detects the overdrive control switch position (ON or OFF) and sends a signal to the TCM.
lThrottle position sensor *
*: This sensor means accelerator pedal position (APP) senror.
Electric throttle control actuator consists of throttle control motor, acceleration pedal position sensor, throt-
tle position sensor, etc. The actuator sends a signal to the TCM.
