Control Module: Testing and Inspection

SOLENOID TRANSISTOR INSPECTION

1. Disconnect control unit connectors.
2. Check continuity between terminals 2K, 2M, 2N, 2O, 2P and 2S.
3. If there is no continuity at any one terminal, replace EC-AT control unit.

TERMINAL VOLTAGE INSPECTION

1. With ignition switch "ON," check EC-AT control unit terminal voltages, referring to terminal voltage chart.
2. If not correct, check and replace or repair defective component(s) and/or wiring.
3. If voltages are not correct and no other cause is detected, replace control unit.
