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.

STEP 5. Check PCM connector C-92 and intermediate 
connector C-96 for loose, corroded or damaged terminals, 
or terminals pushed back in the connector.

Q: Are the connectors and terminals in good condition?

YES : Go to Step 6.
NO :  Repair or replace the damaged components. Refer to
