washer pump C1097 pin 2, circuit 1333 (LB/WH), harness side.
Is the resistance less than 5 ohms?
Yes
GO to E11.
No
REPAIR the circuit. REPEAT the FEM self-test. CLEAR the DTCs.
E11 CHECK THE MULTIFUNCTION SWITCH

self-test. CLEAR the DTCs.
F3 CHECK CIRCUIT 1321 (TN/BK) FOR SHORT TO GROUND
Disconnect: FEM C201b.
Measure the resistance between FEM C201b pin 14, circuit 1321 (TN/BK), harness
side and ground.
Is the resistance greater than 10,000 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.
