STEP 4. Check the continuity at PCM harness side
connector B-20.
(1) Disconnect the connector B-20 and measure at the harness

side.

(2) Measure the continuity between terminals No. 34, No. 38

and ground.

• Should be less than 2 ohms.

Q: Does continuity exist?

YES : Go to Step 5.
NO : Repair harness wire between PCM connector B-20

(terminals No. 34, No. 38) and ground because of
open circuit or harness damage. Then go to Step 8.
