TCM Self-diagnosis Does Not ActivateUCS005VF
SYMPTOM:
OD OFF indicator lamp does not come on in TCM self-diagnostic procedure even if the lamp circuit is
good.
DESCRIPTION

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

Overdrive control switch
Overdrive control switch detects the switch position (ON or OFF)
and sends the 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 sensor, and sends the signal via CAN communi-
cation to the TCM.
DIAGNOSTIC PROCEDURE
NOTE:
The diagnostic procedure includes inspection for the PNP stitch, overdrive control switch, closed throttle posi-
tion signal and wide open throttle position signal circuit. Refer to AT-186, "
PNP, OD SWITCH AND CLOSED
THROTTLE, WIDE OPEN THROTTLE POSITION SIGNAL CIRCUIT" .
