STEP 17. Measure the switch output voltage at PCM
connector D-134.
(1) Disconnect connector D-134 and measure at the harness
side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 77 and ground.
• The voltage should measure battery positive voltage
when the selector lever is upshift and hold.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?
YES : Go to Step 14.
NO : Go to Step 18.

STEP 21. Check shift switch assembly connector E-115 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 22.
NO : Repair or replace the damaged components. Refer to

STEP 22. Measure the switch output voltage at PCM
connector D-134.
(1) Disconnect connector D-134 and measure at the harness
side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 68 and ground.
• The voltage should measure battery positive voltage
when the selector lever is downshift and hold.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?
YES : Go to Step 14.
NO : Go to Step 23.
