STEP 11. Measure the 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) Transmission range should be sport mode.

(4) Measure the voltage between terminal 85 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 14.
NO :  Go to Step 12.
