No MIL
- Turn ignition on. If oil pressure light is on, go to next step. If light is off, inspect fuse No. 13. Replace fuse and repair short as necessary. If fuse No. 13 is okay, repair open circuit in Yellow wire between fuse and instrument cluster.
- Turn ignition off. Connect ECM Test Harness (07LAJ-PT3010A
) between ECM and ECM connectors. See Fig 1
. Connect test terminal A13 to ground. Turn ignition on. If MIL is now on, go to next step. If light is off, replace light bulb or repair open in Blue wire between ECM terminal A13 and instrument cluster.
- Individually measure voltage between ground and test terminals A23 and A24. If more than one volt is present on any terminal, check open in wire between ECM and ground terminal G101 (at intake manifold). See Fig 2
. If less than one volt is present on each terminal, replace ECM and retest.
