I4
CHECK CIRCUIT 28 (BK/PK) FOR A SHORT TO GROUND
Measure the resistance between windshield wiper motor C113 Pin 5, Circuit 28 (BK/PK) harness side and
ground.
Is the resistance greater than 10,000 ohms?
Yes
GO to
I5
.
No
REPAIR Circuit 28 (BK/PK). RESTORE the system. CARRY OUT the FEM self-test. CLEAR the continuous DTCs.
I5
CHECK CIRCUIT 28 (BK/PK) FOR AN OPEN
Measure the resistance between the windshield wiper ON/OFF relay pin 4, battery junction box (BJB) and
windshield wiper motor C113 Pin 5, Circuit 28 (BK/PK) harness side, and windshield wiper ON/OFF relay Pin 4,
BJB and FEM C191 Pin 13, Circuit 28 (BK/PK), harness side.
Are the resistances less than 5 ohms?
Yes
GO to
I6
.
No
REPAIR Circuit 28 (BK/PK). RESTORE the system. CARRY OUT the FEM self-test. CLEAR the continuous DTCs.
I6
CHECK THE WINDSHIELD WIPER MOTOR
Carry out the windshield wiper motor component test. Refer to Windshield Wiper Motor component test in this
section.
Does the windshield wiper motor pass the component test?
Yes
GO to
I7
.
No
INSTALL a new windshield wiper motor. REFER to
Motor — Windshield Wiper
in this section.
I7
CHECK FOR CORRECT FEM OPERATION
Disconnect all the FEM connectors.
Check for:
corrosion
pushed-out pins
Connect all the FEM connectors and make sure they are seated correctly.
Operate the system and verify the concern is still present.
Is the concern still present?
Yes
INSTALL a new FEM. REFER to
Section 419-10
. TEST the system for normal operation.
No
The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
CLEAR the DTCs. REPEAT the self-test.
