PCM PROBLEM INSPECTION PROCEDURE

1. TEST PCM GROUND CIRCUIT: Measure resistance between PCM and chassis ground using the backside of PCM

harness connector as PCM side check point. If the problem is found, repair it.

Specification (Resistance): 1

Ω or less

2. TEST PCM CONNECTOR: Disconnect the PCM connector and visually check the ground terminals on PCM side

and harness side for bent pins or poor contact pressure. If the problem is found, repair it.

3. If problem is not found in Step 1 and 2, the PCM could be faulty. If so, replace the PCM with a new one, and then

check the vehicle again. If the vehicle operates normally then the problem was likely with the PCM.

4. RE-TEST THE ORIGINAL PCM : Install the original PCM (may be broken) into a known-good vehicle and check

the vehicle. If the problem occurs again, replace the original PCM with a new one. If problem does not occur, this
is intermittent problem (Refer to INTERMITTENT PROBLEM PROCEDURE in BASIC INSPECTION
PROCEDURE).

REPLACEMENT

1. Turn ignition switch off.

2. Disconnect the battery (-) cable from the battery.

3. Disconnect the PCM connectors (A).

4. Unscrew the PCM mounting bolts (B) and remove the PCM from the air cleaner assembly.

5. Install a new PCM.
