TCM Self-Diagnosis Does Not Activate INFOID:0000000004305491
SYMPTOM: OD OFF indicator lamp does not come on in TCM sel f-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.

A/T SHIFT LOCK SYSTEM
Description INFOID:0000000004305498
• The mechanical key interlock mechanism also operates as a shift lock: With the ignition switch turned to ON, selector lever cannot be shifted from “P” position to any other position
unless brake pedal is depressed.
With the key removed, selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless selector lever is placed in “P” position.
• The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and sli der located inside key cylinder, respectively.
