Headlight Cleaning System (SRA)

Headlight Cleaning System (SRA)

The headlight washing system is available as of the "parking light on" signal being received by the WIM from the LM.

A headlight wash has 2 spraying cycles.

A headlight wash is activated automatically:

- When the ignition and the light are "on", a headlight wash is always activated the first time the windshield washer system is operated.
- After the first operation, every 5th time a windshield washing operation is activated.

Following a cycle, no further cycles can be activated within an inhibit period of 5 minutes.

The timed arrest and the SRA counter are reset by terminal R "off".

If the control unit identifies the need to refill the water tank, a headlight wash is only activated with every eighth wash requested. This requirement is identified by the Instrument Cluster (message via K-CAN S).
