Electronic Control Unit (Ecu)

Obtain access to ECU. See Figure. Turn ignition on. Using voltmeter, check voltage between designated terminals on ECU with connector installed on ECU. Voltage should be as specified. See Fig 1 and Fig 2.
Turn ignition off. Using ohmmeter, check for continuity between specified terminals. Continuity should be as specified. See Fig 1 and Fig 2.

NOTE: Connector "A" goes to shift lock solenoid. Connector "B" goes to ignition switch and brakelight switch. Connector "C" goes to shift lock control switch.
