Control Module: Testing and Inspection

INSPECTION





1. Remove the front console cover of the passenger's side.





2. Connect the SST (Engine Signal Monitor) between the engine control unit and the wiring harness using the SST (Adapter) as shown.

Note: Use connector A of the Adapter to check voltages at the terminals lA through lV and 3A through 3Z, and use connector B to check the voltages at the terminals 2A through 2P.





3. Place the SST (Sheet) on the SST (Engine Signal Monitor).
4. Measure the voltage at each terminal.
5. If any engine control unit terminal voltage is incorrect, check the input or output device and related wiring.

If they are normal, replace the engine control unit.

Caution: Never apply voltage to SST terminals A and B.
