FEM C191
Measure the resistance between FEM C191 Pin 13, Circuit 28 (BK/PK), harness side and wiper ON/OFF relay
Pin 4, Circuit 28 (BK/PK), harness side, and windshield wiper motor C113 Pin 5, Circuit 28 (BK/PK), 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 28 (BK/PK). REPEAT the FEM self-test, CLEAR the DTCs.
E4 CHECK WIPER ON/OFF RELAY FOR CORRECT OPERATION
Wiper ON/OFF Relay
Check the wiper ON/OFF relay for correct operation. Refer to Wiring Diagram Cell 149.
 Is the wiper ON/OFF relay OK?
Yes
GO to E5.
No
INSTALL a new wiper ON/OFF relay. REPEAT the FEM self-test, CLEAR the DTCs.
E5 CHECK CIRCUIT 28 (BK/PK) FOR SHORT TO VOLTAGE
FEM C191
Measure the voltage between wiper ON/OFF relay Pin 4, Circuit 28 (BK/PK), harness side and ground.
 Is any voltage indicated?
Yes
REPAIR Circuit 28 (BK/PK). REPEAT the FEM self-test, CLEAR the DTCs.
No
INSTALL a new FEM. For additional information, REFER to Section 419-10. REPEAT the FEM self-test, CLEAR
the DTCs.
E6 CHECK THE MULTIFUNCTION SWITCH
Multifunction Switch C263
Check the multifunction switch for correct operation. Refer to Wiring Diagram Cell 149.
 Is the multifunction switch OK?
Yes
GO to E7.
No
INSTALL a new multifunction switch. For additional information, REFER to Section 211-05. REPEAT the FEM self-
test, CLEAR the DTCs.
E7 CHECK CIRCUIT 640 (RD/YE) FOR SHORT TO VOLTAGE
FEM C346
Measure the voltage between FEM C346 Pin 3, Circuit 640 (RD/YE), harness side and ground.
