Circuit/System Verification
Operate the front washer by using the S80 Window Wiper/Washer Switch. Verify the G24 Windshield Washer Pump activates.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the X50A Fuse Block - Underhood.
2. Disconnect the harness connector X4 at the K9 Body Control Module.
3. Test for less than 5 ohm between the control circuit terminal 14 at the X50A Fuse Block - Underhood and the control circuit terminal 14 X4
at the K9 Body Control Module.
瀚慖f the value is not within the specified range, test the control circuit for a short to voltage or an open/high resistance.
瀚慖f the circuit tests normal, test or replace the K9 Body Control Module.
4. Test for infinite resistance between the control circuit terminal 14 at the X50A Fuse Block - Underhood and ground.
瀚慖f the value is not within the specified range, test the control circuit for a short to ground.
5. If all circuits test normal, test or replace the X50A Fuse Block - Underhood.
Component Testing
Relay Test
1. Ignition OFF, disconnect the harness connector X5 at the K9 Body Control Module.
2. Test for 60-200 ohm between control circuit terminal 14 X4 at the K9 Body Control Module and ground.
瀚慖f the value is not within the specified range, test the control circuit for a short to ground, short to voltage or an open.
瀚慖f all circuits test normal, test or replace the X50A Fuse Block - Underhood.
Output Control Tests
Ignition ON, command the Windshield Washer Relay Command ON and OFF with a scan tool. Observe that the KR11 Windshield Washer Pump
Relay clicks and the G24 Windshield Washer Pump runs.
If the KR11 Windshield Washer Pump Relay does not work, replace the X50A Fuse Block - Underhood.
If the KR11 Windshield Washer Pump Relay works, but the G24 Windshield Washer Pump does not run, test the washer fluid pump control circuit
and the washer fluid pump ground circuit.
If all circuits test normal, replace the G24 Windshield Washer Pump.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
