Windshield Wiper System

Windshield Wiper System

CAUTION!
• When connecting battery, always perform work procedure as described in repair information --> [ Battery, with Auxiliary Battery or Two-Battery Layout, Disconnecting and Connecting ] Battery, with Auxiliary Battery or Two-Battery Layout, Disconnecting and Connecting. Not adhering to sequence will result in the deactivation of Main Battery Switch -E74- and subsequent damage to electrical system components.

• Observe notes for threaded connections of battery terminals --> [ Battery Post/Terminal ] Battery Post/Terminal.

• The function of the windshield wiper system can be checked via the wiper motor control module (J400) output Diagnostic Test Mode (DTM).

• Additional information:

--> Owner's Manual

General Description:

• Hood (Front Hood Switch (F266)) must be closed to activate windshield wiper functions.

Control Module for wiper motor (J400) is integrated in Windshield Wiper Motor (V).

• If Control Module for wiper motor (J400) or Windshield Wiper Motor (V) is replaced, Control Module for wiper motor (J400) must be coded --> [ Wiper Motor Control Module, Coding ] Testing and Inspection.

Rain Sensor (G213) or Rain/Light Recognition Sensor (G397) may be installed, depending on equipment.

Rain Sensor (G213) function is activated via Windshield Wiper/Washer Switch (E22) --> [ Steering Column Switch Assembly Overview ] Steering Column Switch Assembly Overview.

• Observe notes for operation for Rain Sensor (G213) --> owner's manual.

Rain Sensor (G213) registers rain intensity which it converts to a corresponding signal. This signal is then received by Control Module for wiper motor (J400) and then transmitted to Windshield Wiper Motor (V).

The Rain/Light Recognition Sensor (G397) controls the Automatic Driving Lights Control (ADLC) function in addition to the functions of Rain Sensor (G213) listed above.

The ADLC (Automatic Driving Lights Control) function is activated via Light Switch (E1) --> [ Light Switch ] Service and Repair.

• Observe notes for operation for "automatic driving lamps control " --> owner's manual.

The Rain/Light Recognition Sensor (G397) also registers light intensity which it converts to a corresponding signal. Wiper Motor Control Module (J400) receives this signal first and then relays it via instrument cluster to Vehicle Electrical System Control Module (J519), which switches the driving lamps on.

DTC recognition and display:

Wiper Motor Control Module (J400) and Vehicle Electrical System Control Module (J519) are equipped with On Board Diagnostic (OBD), which assists troubleshooting.

For troubleshooting, use Vehicle Diagnostic, Testing and Information System (VAS 5051A) in operating mode " Guided Fault Finding".
