Measure the resistance between FEM C191 Pin 1, Circuit 1318 (DG/WH), harness side and windshield wiper
ON/OFF relay Pin 2, Circuit 1318 (DG/WH), harness side.
Is the resistance less than 5 ohms?
Yes
INSTALL a new FEM. For additional information, REFER to
Section 419-10
. REPEAT the FEM self-test, CLEAR
the DTCs.
No
REPAIR Circuit 1318 (DG/WH). REPEAT the FEM self-test, CLEAR the DTCs.
B4
CHECK THE WIPER ON/OFF RELAY
Windshield Wiper ON/OFF Relay
Measure the voltage between windshield wiper ON/OFF relay Pin 2, Circuit 1318 (DG/WH), harness side and
ground.
Is the voltage greater than 10 volts?
Yes
GO to
B5
.
No
INSTALL a new wiper ON/OFF relay. REPEAT the FEM self-test, CLEAR the DTCs.
B5
CHECK CIRCUIT 1318 (DG/WH) FOR SHORT TO VOLTAGE
FEM C191
Windshield Wiper ON/OFF Relay
Measure the voltage between windshield wiper ON/OFF relay Pin 2, Circuit 1318 (DG/WH), harness side and
ground.
Is the voltage greater than 10 volts?
Yes
REPAIR Circuit 1318 (DG/WH). REPEAT the FEM self-test, CLEAR the DTCs.
No
INSTALL a new FEM. For additional information, REFER to
Section 419-10
.
B6
CHECK FOR MULTIPLE DTCS
Use the recorded results from the FEM self-test.
