Check relay coil driver for an intermittent short circuit to voltage supply by checking the voltage on 2 in the relay socket to relay 2/59.
For additional information regarding a short circuit to voltage supply, see Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.

Hint: The voltage between 2 and ground must be approximately 0 V.








If the voltmeter indicates an incorrect value, the control unit should be replaced.
