STEP 22. Check transmission range switch connector C-04
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 23.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

P.00E-2

.

STEP 23. Measure the transmission range switch output
voltage at PCM connector D-134 by backprobing.
(1) Do not disconnect connector D-134.
(2) Turn the ignition switch to the "ON" position.
(3) Move the selector lever to the "N" position.

(4) Measure the voltage between terminal 75 and ground by

backprobing.

• The voltage should measure battery positive voltage.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?

YES : Go to Step 13.
NO : Go to Step 24.
