Is the resistance less than 5 ohms?
A3 CHECK CIRCUIT 1318 (DG/WH) FOR OPEN
Disconnect: FEM C201b.
Measure the resistance between FEM C201b 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. REFER to Section
419-10. REPEAT the FEM self-test.
CLEAR the DTCs.
No
REPAIR the circuit. REPEAT the FEM
self-test. CLEAR the DTCs.
A4 CHECK THE WIPER ON/OFF RELAY
Disconnect: 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 A5.
No
INSTALL a new wiper ON/OFF relay.
REPEAT the FEM self-test. CLEAR the
DTCs.
A5 CHECK CIRCUIT 1318 (DG/WH) FOR SHORT TO VOLTAGE
Disconnect: FEM C201b.
Disconnect: 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 the circuit. REPEAT the FEM
self-test. CLEAR the DTCs.
No
INSTALL a new FEM. REFER to Section
419-10.
A6 CHECK FOR MULTIPLE DTCS
Use the recorded results from the FEM self-test.
Is DTC B1450 also present?
Yes
GO to A9.
No
GO to A7.
A7 CHECK THE MULTIFUNCTION SWITCH
Disconnect: Multifunction Switch C202.
Carry out the multifunction switch component test.
Refer to Wiring Diagrams Cell 149, Interval Wiper/Washer for component testing.
Is the multifunction switch OK?
Yes
GO to A8.
No
INSTALL a new multifunction switch.
REFER to Section 211-05. REPEAT the
FEM self-test. CLEAR the DTCs.
A8 CHECK CIRCUIT 1301 (YE) FOR OPENS
Measure the resistance between FEM C201d pin 2, circuit 1301 (YE), harness side and multifunction switch C202 pin 5, circuit
1301 (YE), harness side.
Yes
INSTALL a new FEM. REFER to Section
419-10. REPEAT the FEM self-test.
CLEAR the DTCs.
No
