Cruise Control Module and Its Circuit Inspection
VOLTAGE CHECK
Check for input or output voltage of control module (voltage between each circuit and body ground) with cruise
control module connector connected.CAUTION:
Cruise control module can not be checked by itself. It is strictly prohibited to connect voltmeter or
ohmmeter to cruise control module with coupler disconnected from it.
