A7 CHECK THE INPUT TO THE SCCM (STEERING COLUMN CONTROL MODULE)
Using a diagnostic scan tool, view the SCCM Parameter Identifications (PIDs). Using a diagnostic scan tool, view the following SCCM wiper/washer switch Parameter Identifications (PIDs):
WIPE_SINGLE F_WASH_SW F_WIP_INT_D1 F_WIP_INT_D2 F_WIP_INT_D3 F_WIP_INT_D4 F_WIP_INT_D5 F_WIP_INT_D6 F_WIP_SLO_SW F_WIPE_FAST_SW
Cycle the wiper/washer switch from off to the high speed setting and then back to off.
Do the Parameter Identifications (PIDs) correspond correctly with each setting selection?
Yes | GO to A8 |
|---|---|
No | INSTALL a new wiper/washer switch. REFER to: Steering Column Multifunction Switch RH (211-05 Steering Wheel and Column Electrical Components, Removal and Installation). TEST the system for normal operation. If the concern is still present, INSTALL a new SCCM. REFER to: Steering Column Control Module (SCCM) (211-05 Steering Wheel and Column Electrical Components, Removal and Installation). |
