Checking Wiring

Remove relay 2/116.

Check the relay coil driver circuit for an intermittent short-circuit to supply voltage: Take a voltmeter reading between terminal #2 and ground in the relay base for relay (2/116).

For further information about a short-circuit to supply voltage, see Short-circuit to supply voltage, intermittent faults .

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