PINPOINT TEST G: THE HIGH/LOW WIPER SPEEDS DO NOT OPERATE CORRECTLY
Is the resistance greater than 10,000 ohms?
No
REPAIR the circuit. REPEAT the FEM self-test. CLEAR the DTCs.
Test Step Result / Action to Take
G1 USE THE RESULTS FROM FEM SELF-TEST
Use the recorded results from FEM self-test.
Are any DTCs recorded?
Yes
If DTC B1436, GO to G2 .
No
GO to G4.
G2 CHECK WIPER HIGH/LOW RELAY
Disconnect: Wiper HIGH/LOW Relay.
Check the wiper HIGH/LOW relay for correct operation.
Refer to Wiring Diagrams Cell 149, Interval Wiper/Washer for component testing.
Is the wiper HIGH/LOW relay OK?
Yes
With the wiper HIGH/LOW relay disconnected,
GO to G3 .
No
INSTALL a new wiper HIGH/LOW relay. REPEAT
the FEM self-test. CLEAR the DTCs.
G3 CHECK CIRCUIT 1319 (VT/WH) FOR SHORT TO VOLTAGE
Disconnect: FEM C201b.
Measure the voltage between FEM C201b pin 3, circuit 1319 (VT/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.
REPEAT the FEM self-test. CLEAR the DTCs.
G4 CHECK WIPER HI /LOW RELAY — USE ACTIVE COMMAND SPEED RLY
Enter the following diagnostic mode on the scan tool: FEM active command SPEED RLY to ON.
Does the HIGH/LOW relay energize?
Yes
GO to G5.
No
INSTALL a new FEM. REFER to Section 419-10.
REPEAT the FEM self-test. CLEAR the DTCs.
G5 CHECK WIPER HIGH/LOW RELAY
Disconnect: Wiper HIGH/LOW Relay.
Check the wiper HIGH/LOW relay for correct operation.
Refer to Wiring Diagrams Cell 149, Interval Wiper/Washer for component testing.
Is the wiper HIGH/LOW relay OK?
Yes
GO to G6.
No
INSTALL a new wiper HIGH/LOW relay. REPEAT
the FEM self-test. CLEAR the DTCs.
G6 CHECK THE CIRCUIT 1319 (VT/WH) FOR SHORT TO GROUND
Disconnect: FEM C201b.
Measure the resistance between FEM C201b pin 3, circuit 1319 (VT/WH), harness side and ground.
Is the resistance greater than 10,000 ohms?
Yes
GO to G7.
No
REPAIR the circuit. REPEAT the FEM self-test.
CLEAR the DTCs.
G7 CHECK THE CIRCUIT 1319 (VT/WH) FOR OPEN
Measure the resistance between FEM C201b pin 3, circuit 1319 (VT/WH), harness side and wiper HIGH/LOW relay pin
2, circuit 1319 (VT/WH), harness side.
Yes
GO to G8.
No
REPAIR the circuit. REPEAT the FEM self-test.
