Pinpoint Test I: B1008:09: Wiper Mode Switch: Component Failure
- I1 CHECK THE STEERING WHEEL HARNESS CIRCUITS FOR AN OPEN
- Disconnect Clockspring C218B.
- Disconnect Steering wheel switch RH C2999.
- Measure:
Positive Lead Measurement / Action Negative Lead C2999-3 C218B-7 C2999-5 C218B-6 C2999-9 C218B-16
Are the resistances less than 3 ohms?
Yes GO to I2 No INSTALL a new steering wheel harness. REFER to: Steering Wheel Multifunction Switch . - I2 CHECK THE STEERING WHEEL HARNESS CIRCUITS FOR A SHORT TO GROUND
Are the resistances greater than 10, 000 ohms?
Yes GO to I3 No INSTALL a new steering wheel harness. REFER to: Steering Wheel Multifunction Switch . - I3 CHECK THE STEERING WHEEL HARNESS CIRCUITS FOR A SHORT TOGETHER
- Measure:
Positive Lead Measurement / Action Negative Lead C2999-3 C2999-5 C2999-5 C2999-9 C2999-9 C2999-3
Are the resistances greater than 10, 000 ohms?
Yes INSTALL a new steering wheel multifunction switch. REFER to: Steering Wheel Multifunction Switch . If concern is still present, GO to I4 No GO to I4 - Measure:
- I4 CHECK FOR CORRECT SCCM (STEERING COLUMN CONTROL MODULE) OPERATION
- Disconnect and inspect all the SCCM connectors.
- Repair:
- corrosion (install new connector or terminal - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the SCCM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new SCCM. REFER to: Steering Column Control Module (SCCM) . No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
