Operation CHARM: Car repair manuals for everyone.

General System Description

The windshield wiper system is controlled by the central body electronics control module. The three wiper relays and the washer relay are activated by the relay module. The relay outputs are routed via diagnostic links to the general module. All functions may be switched on and off with the wiper switch. The ignition switch must be in position one or further to operate the wiper system.
During intermittent wiper operation, the wiper speed and wiper cycle is dependent upon the vehicle speed.
