PCME Pin Tests

POWERTRAIN CONTROL MODULE ENGINE (PCME)





Inspection
1. Remove the scuff plate (passenger side) and the front side trim (passenger side).
2. Remove the PCME bolts and nut.








3. Connect the Special Service Tool (SST) to the PCME as shown. Use connector A of the adapter to measure voltage at terminals 1A through 1V and 3A through 3Z, and use connector B to measure voltage at terminals 2A through 2P.





4. Place the SST (Sheet: 64-pin type) on the SST (Engine Signal Monitor).
5. Measure the voltage at each terminal.

Refer to Terminal Voltage Charts. PCME Terminal Voltage Charts

6. 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 and B will damage the SST.
