Signal Too High

Signal too high

Checking the component
Replace relay 2/182.
Activate high-pressure cleaning by activating the windshield washer.

Hint: The washer must be activated for more than 0.3 seconds before high pressure cleaning will be activated. High-pressure cleaning is activated every fifth time the washers are activated if not more than 10 minutes have passed since the last activation.

If the function is OK, the cause of the fault was a damaged relay (short-circuit in the relay).

Other information:
- For further information about fuses and relays, see the relevant wiring diagram.

Was a fault detected?

Yes - Verification

No - Checking fusebox

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

Checking fusebox
Remove windshield wiper relay 2/182 from the fusebox base.
Check the relay coil driver circuit for a short-circuit to supply voltage. Take a voltmeter reading between terminal #2 and ground in the relay base.
The voltage between terminal #2 and ground must be approximately 0 V.
Remedy as necessary.
