STEP 13. Check PCM connector D-134 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 5.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

P.00E-

.

STEP 14. Check the transmission range switch.
Measure the resistance between the terminals for each selec-
tor position as indicated in the table above.

Q: Does the resistance measure less than 2 ohms for each

selector position?
YES : Go to Step 15.
NO : Replace the transmission range switch. Refer to

GROUP 23B, Transmission

STEP 15. Check transmission range switch connector C-04
the 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 16.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

P.00E-

.

STEP 16. 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 "R" position.

(4) Measure the voltage between terminal 67 and ground by

backprobing.

• The voltage should measure battery positive voltage.

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

YES : Go to Step 13.
NO : Go to Step 17.
