Signal Too High

Signal too high

Replacing the component
Replace the relay, 2/67 (2/87 5DRS).
Activate the relay.
If the function is OK, the cause of the fault was a defective relay (short-circuit in the relay).

Other information
- For further information about the fuses and relays, see the Wiring Diagram.









Was the function OK?

Yes - Fault Found

No - Checking the wiring

-------------------------------------------------

Checking the wiring
- Remove the relay.
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.
