TCM Self-diagnosis Does Not ActivateBCS0014V
SYMPTOM:
A/T CHECK indicator lamp does not come on in TCM self-diagnostic procedure even if the lamp circuit
is good.
DESCRIPTION

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

3rd position switch
3rd position switch detects the 3rd position and sends a signal via CAN communication 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 (APP) sensor, and sends
the signal via CAN communication to TCM.

Stop lamp switch
Stop lamp switch detects the switch position (ON or OFF) and sends a signal via CAN communication to
the TCM.
DIAGNOSTIC PROCEDURE
NOTE:
The diagnostic procedure includes inspection for the park/neutral position (PNP) stitch, 3rd position switch,
stop lamp switch, closed throttle position signal and wide open throttle position signal circuit. Refer to AT- 1 6 1 ,
"PNP, 3RD POSITION SWITCH AND CLOSED THROTTLE, WIDE OPEN THROTTLE POSITION SIGNAL"
and AT- 1 6 7 , "BRAKE SIGNAL CIRCUIT" .

the hole in PNP switch.
5. Tighten PNP switch fixing bolts to the specified torque. Refer to
AT- 2 3 0 , "
COMPONENTS" .
6. Remove pin from adjustment hole after adjusting PNP switch.
7. Check continuity of PNP switch. Refer to AT- 1 6 1 , "
