PCME Pin Tests

Inspection with Engine Signal Monitor
1. Connect the special service tools SSTs to the powertrain control module engine (PCME) as shown.

NOTE: Use connector A of the adapter to measure voltage at terminals 1A through lV and 3A through 3P, and use connector B to measure voltage at the terminals 2A through 2L and 4A through 4Z.

2. Place the SST (Sheet: 76-pin type) on the SST (Engine Signal Monitor).
3. Measure the voltage at each terminal.

See: PCME Terminal Voltage Charts.

4. If any PCME terminal voltage is incorrect, check the input or output device and related wiring. If they are normal, replace the PCME.

CAUTION: Applying voltage to SST terminals A or B will damage the SST.
