Checking The Control Module

Check the relay coil driver circuit for a short-circuit to supply voltage by measuring the voltage at terminal #2 in the relay base.

HINT: The voltage between terminal #2 and ground should be approximately 0 V. 

Replace the control module if the voltmeter displays an incorrect value.
