Test Procedure
- Remove ECM to access ECM connector terminals (if necessary). See Fig 1 -Fig 3 . With ECM connectors connected, backprobe terminal specified in charts. See Fig 4 -Fig 9 . Measure voltage between terminal specified in chart and ECM connector terminal No. 106 (ground).
- If voltmeter shows any deviation from standard value, check corresponding sensor, actuator and related wiring. After repair or replacement, recheck to ensure problem is corrected.
