PINPOINT TEST H : The Washer Pump Is Inoperative/Always On

NOTE: The following Pinpoint Test uses a test lamp to simulate normal circuit loads. Use only the test lamp recommended. To avoid connector terminal damage, use the Flex Probe Kit for the test lamp probe connection to the vehicle. Do not use the test lamp probe directly on any connector.

  1. H1 CHECK THE WASHER SWITCH FRONT (F_WASH_SW) AND WASHER SWITCH REAR (R_WASH_SW) PIDs

    Do each of the PIDs change to the ON state when the wiper/washer switch is in the applicable WASH positions? 

    Yes  GO to  H2.
    No  For vehicles without the police package, INSTALL a new wiper/washer switch. REFER to Wiper and Washer Switch . If the concern is still present, INSTALL a new SCCM. REFER to STEERING COLUMN CONTROL MODULE (SCCM) . For vehicles with the police package, INSTALL a new multifunction switch. REFER to STEERING COLUMN MULTIFUNCTION SWITCH . If the concern is still present, INSTALL a new SCCM. REFER to STEERING COLUMN CONTROL MODULE (SCCM) .
