AUTOMATIC TRANSMISSION

23A-143

STEP 28. Check the transmission range switch.
Measure the resistance between the terminals for each trans-
mission range as indicated in the table below.

Q: Is the measured resistance less than 2 ohms for each

transmission range?
YES : Go to Step 29.
NO : Replace the transmission range switch. Refer to

GROUP 23B, Transmission

P.23B-14

.

STEP 29. Check transmission range switch connector C-04
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is the connector in good condition?

YES : Go to Step 30.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

STEP 30. 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 "D" position.

(4) Measure the voltage between terminal 76 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 31.
