- Turn ignition off and disconnect both battery cables. Disconnect Powertrain Control Module (PCM). PCM is located next to air cleaner. Using external ohmmeter, measure resistance of Yellow/Violet wire between PCM Gray 80-pin connector C2 terminal No. 59 and DLC terminal No. 2. If resistance is 320-2000 ohms, replace PCM. If resistance is not 320-2000 ohms, repair open Yellow/Violet wire.
