STEP 12. Measure the resistance at PCM connector D-134
by backprobing.
(1) Do not disconnect connector D-134.
(2) Turn the ignition switch to the "ON" position.

(3) Measure the resistance between terminal 88 and ground by

backprobing.

• The resistance should measure less than 2 ohms.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured resistance less than 2 ohms?

YES : Go to Step 13.
NO : Go to Step 15.
