Pinpoint Test W : The Steering Wheel Switches Are Inoperative Or Do Not Operate Correctly
- W1 RETRIEVE THE RECORDED DTCs FROM THE IPC SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Is DTC U0212:00 recorded?
Yes Refer to article 'Instrumentation, Message Center, and Warning Chimes', Go to Pinpoint Test AZ . No GO to W2. - W2 CHECK THE RH STEERING WHEEL SWITCH PIDs
- Using a diagnostic scan tool, view SCCM PIDs.
- Monitor the steering wheel switches PIDs while pressing each steering wheel switch.
- OK (R_CURS_OK)
- UP CURSOR (R_CURS_UP)
- DOWN CURSOR (R_CURS_DWN)
- LEFT CURSOR (R_CURS_LFT)
- RIGHT CURSOR (R_CURS_RGT)
- VOL+ (SW_VOLDOWN)
- VOL- (SW_VOLUP)
- SEEK+ (SW_SEEKPLUS)
- SEEK- (SW_SEEKMINUS)
- PHONE (SW_PHONE)
- VOICE (SW_VOICE)
Do the PID values agree with the switch positions?
Yes GO to W6. No If only one PID value is incorrect or the PID value always reads one particular switch position, INSTALL a new steering wheel switch. REFER to Steering Column Switches . Otherwise, GO to W3. - W3 CHECK FOR VOLTAGE TO THE RH STEERING WHEEL SWITCHES
- Ignition OFF and wait one minute.
- Remove the driver air bag module. REFER to Supplemental Restraint System .
- Disconnect: RH Steering Wheel Switch.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C2999-2 C2999-5 C2999-3 C2999-5 C2999-8 C2999-5 C2999-10 C2999-5
Are the voltages approximately 5 volts?
Yes INSTALL a new RH steering wheel switch. REFER to Steering Column Switches . No GO to W4. - W4 CHECK FOR VOLTAGE TO THE CLOCKSPRING
- Ignition OFF.
- Disconnect: Clockspring C218B .
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead (Component side) C218B-6 (Component side) C218B-16 (Component side) C218B-7 (Component side) C218B-16 (Component side) C218B-14 (Component side) C218B-16 (Component side) C218B-15 (Component side) C218B-16
Are the voltages approximately 5 volts?
Yes INSTALL a new steering wheel. REFER to Steering Column . No GO to W5. - W5 CHECK FOR VOLTAGE AT THE SCCM
- Ignition OFF.
- Remove the clockspring. REFER to Supplemental Restraint System .
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead (Component side) C2414D-5 (Component side) C2414D-10 (Component side) C2414D-6 (Component side) C2414D-10 (Component side) C2414D-7 (Component side) C2414D-10 (Component side) C2414D-8 (Component side) C2414D-10
Are the voltages approximately 5 volts?
Yes INSTALL a new clockspring. REFER to Supplemental Restraint System . No GO to W6. - W6 CHECK FOR APIM DTCs
- Using a diagnostic scan tool, perform the APIM self-test.
Are any APIM DTCs recorded?
Yes Refer to DTC chart . No GO to W7. - W7 CHECK FOR CORRECT SCCM OPERATION
- Ignition OFF.
- Disconnect and inspect all the SCCM connectors.
- Repair:
- Corrosion (clean module pins or install new connectors or terminals)
- Damaged or bent pins (install new terminals or 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 TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new SCCM. REFER to Steering Column Switches . No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
