Washer System & Wiper System: Other Mazda Tribute I

WIPERS AND WASHERS

Refer to the WIPER/WASHER Wiring Diagram for schematic information.

Rear Window Wiper Washer

The generic electronic module (GEM) allows operation of the rear window wiper functions when the ignition switch is in the RUN or ACC position only. The GEM controls the cycling of the rear window wiper motor through a single relay (rear window wiper relay).

There are four modes of operation: off mode, interval mode, on mode and wash mode.

Note. The GEM does not control the rear window washer, only the rear window wiper.

In the off mode, there is no liftgate wiper motor activity and the liftgate wiper motor will be in the PARK position. When the wiper/washer switch is placed in the interval position, the GEM will activate the rear window wipe cycle of the rear window wiper motor. Once the wiper cycle has reaches the LO position, after the initial wipe, the GEM will start a cyclical timing function.

In the ON mode, the GEM will cycle the rear window motor continuously at a set- speed setting. The GEM provides a ground to activate the rear window wiper relay. The wash mode can only be activated when the rear wiper switch is in the OFF or ON positions. When the rear wiper switch is in the OFF position and wash mode is activated, the rear window wiper will not cycle.

Fluid for the rear window washer is supplied by a washer pump located in the rear passenger compartment.

1. Verify the customer concern by operating the system.
2. Visually inspect for obvious signs of mechanical and electrical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the WDS or equivalent Tester does not power up, refer to the WDS or equivalent Tester manual.
5. Carry out the DATA LINK DIAGNOSTICS test. If the WDS or equivalent Tester responds with: CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to COMMUNICATIONS NETWORK . NO RESP/NOT EQUIP for GEM, Refer to PINPOINT TEST 1: NO COMMUNICATION WITH THE GENERIC ELECTRONIC MODULE (GEM) . SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the GEM.
6. If the DTCs retrieved are related to the concern, go to the GEM Diagnostic Trouble Code (DTC) Index to continue diagnostics.
7. If no DTCs related to the concern are retrieved, proceed to the «GEM DIAGNOSTIC TROUBLE CODE (DTC) INDEX»(ref-155139-S03623116162005020900000) to continue diagnostics.

Windshield Wiper Motor

Use an Alternator, Regulator, Battery and Starter Tester (ARBST) to test the wiper motor on the vehicle.

To test the wiper motor, disconnect the windshield wiper mounting arm and pivot shaft from the windshield wiper motor; refer to WIPER PIVOT ARM - FRONT or WIPER PIVOT ARM - REAR .

Disconnect the wiper motor. Connect the (1) green lead from (2) Alternator, Regulator, Battery and Starter Tester (ARBST) to the battery negative (-) post. Connect the (3) red lead from ARBST to the wiper motor (4) common brush terminal (terminal 3).

Test the low-speed mode by connecting a (5) cable from the battery positive (+) post to the (6) low-speed brush terminal (terminal 4) and measure the current draw. If the current draw is greater than 3.5 amperes, install a new windshield wiper motor.

Test the high-speed mode by connecting a cable from the battery positive (+) post to the (7) high-speed brush terminal (terminal 5) and measure the current draw. If the current draw is greater than 5.5 amperes, install a new wiper motor.
