CRUISE CONTROL: CRUISE CONTROL SYSTEM: TERMINALS OF ECU

1. CHECK ECM





HINT
As the ECM connector is a waterproof connector, it is not possible to check the voltage of each terminal or check the waveform with an oscilloscope while the ECM is installed in the vehicle.

(a) Disconnect the A38 and C53 ECM connectors.

(b) Measure the voltage and resistance according to the value(s) in the table below.





If the result is not as specified, there may be a malfunction on the wire harness side.
