Cranking Signal: Testing and Inspection

PREPARATION
Connect the special service tools (SST) to the powertrain control module engine (PCME).

SST-49 G018 903 Adapter Harness, SST-49 9200 162A Eng. Signal Monitor, SST-49 G018 904 Sheet Overlay:

1. Connect the SST engine signal monitor between the PCME and the vehicle's PCME connector by using the SST adapter harness.

SST Sheet Overlay-49 G018 904:

2. Place the SST engine signal sheet overlay on the SST engine signal monitor.
3. Turn ignition switch ON.
4. Measure voltage at PCME terminal 1C.

Condition:--Ignition key-ON.
Voltage:--Below 1.0 Volt.

Condition:--While cranking.
Voltage:--Cranking battery voltage (approx. 10 Volts.)

If readings are not as shown, then inspect the ignition switch, the wiring between the ignition switch and PCME terminal 1C.
