    • Are the resistances greater than 10, 000 ohms? 
    • Yes  : GO to  G10.
    • No  : REPAIR the affected circuit. CLEAR the BCM DTCs. REPEAT the self-test. TEST the system for normal operation.
  7. G7 CHECK FOR VOLTAGE AND GROUND TO THE WASHER PUMP MOTOR 
    • Disconnect: Washer Pump Motor C137.
    • NOTE: On 5-door hatchback vehicles, make sure to operate both the front and rear washer modes.
