Is the resistance less than 5 ohms?
CLEAR the DTCs.
G8 CHECK CIRCUIT 65 (DG) FOR OPEN
Connect: FEM C201b.
Measure the voltage between wiper HIGH/LOW relay pin 1, circuit 65 (DG), harness side and ground.
Is the voltage greater than 10 volts?
Yes
GO to G9.
No
REPAIR the circuit. REPEAT the FEM self-test.
CLEAR the DTCs.
G9 CHECK CIRCUIT 589 (OG) FOR OPEN
Disconnect: Wiper ON/OFF Relay.
Measure the resistance between wiper HIGH/LOW relay pin 3, circuit 589 (OG), harness side and wiper ON/OFF relay
circuit 589 (OG), harness side.
Is the resistance less than 5 ohms?
Yes
REINSTALL ON/OFF relay, GO to G10 .
No
REPAIR the circuit. REPEAT the FEM self-test.
CLEAR the DTCs.
G10 CHECK CIRCUIT 56 (DB/OG) AND 58 (WH) FOR SHORT TO GROUND
Disconnect: Front Wiper Motor C125.
Measure the resistance between wiper HIGH/LOW relay pin 5, circuit 56 (DB/OG), harness side and ground; and
between wiper HIGH/LOW relay pin 4, circuit 58 (WH), harness side and ground.
Is the resistance greater than 10,000 ohms?
Yes
GO to G11.
No
REPAIR Circuit 58 (WH) or circuit 56 (DB/OG), as
necessary. REPEAT the FEM self-test. CLEAR
the DTCs.
G11 CHECK CIRCUIT 56 (DB/OG) AND 58 (WH) FOR OPEN
Measure the resistance between wiper HIGH/LOW relay pin 5, circuit 56 (DB/OG), harness side and windshield wiper
motor C125 pin 1, circuit 56 (DB/OG), harness side; and between wiper HIGH/LOW relay pin 4, circuit 58 (WH), harness
side and windshield wiper motor C125 pin 2, circuit 58 (WH), harness side.
Is the resistance less than 5 ohms?
Yes
GO to G12.
No
REPAIR the circuit as necessary. REPEAT the
FEM self-test. CLEAR the DTCs.
G12 CHECK CIRCUIT 56 (DB/OG) AND 58 (WH) FOR SHORT TO VOLTAGE
