STEP 3. Measure the switch output voltage at transfer low
detection switch connector B-17.

(1) Disconnect connector B-17 and measure at the harness

side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 1 and ground.

• The voltage should measure battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?

YES : Go to Step 10.
NO : Go to Step 4.

STEP 4. Measure the switch output voltage at PCM
connector C-92 by backprobing.

(1) Do not disconnect connector C-92.
(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 112 and ground by

backprobing.

• The voltage should measure battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?

YES : Go to Step 5.
NO : Go to Step 7.
