PINPOINT TEST C : The Cruise Control Switch Is Inoperative Or Does Not Operate Correctly
- C1 CHECK THE CRUISE CONTROL SWITCH
- Ignition ON.
- Using a scan tool, view the SCCM PIDs.
- Press each cruise control switch while monitoring the cruise control switch PID (SCCS).
Cruise Control Switch SCCS PID Value - None pressed RES/CNCL RESUME/CANCEL ON/OFF On/Off SET (pressed up) SET/+ SET (pressed down) SET/- GAP (pressed up) GAP- GAP (pressed down) GAP+
Does the PID value agree with the switch position?
Yes GO to C5. No If only one switch value does not display the correct PID value, INSTALL a new LH steering wheel switch. REFER to Steering Column Switches . Otherwise, GO to C2. - C2 CHECK FOR VOLTAGE TO THE CRUISE CONTROL SWITCHES
- Ignition OFF.
- Remove the driver air bag module. REFER to Supplemental Restraint System .
- Disconnect LH Steering Wheel Controls.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C2998-4 C2998-1 C2998-6 C2998-1 C2998-8 C2998-1
Is the voltage approximately 5 volts?
Yes INSTALL a new LH steering wheel switch. REFER to Steering Column Switches . No GO to C3. - C3 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-8 (component side) C218B-7 (component side) C218B-8 (component side) C218B-15 (component side) C218B-8
Is the voltage approximately 5 volts?
Yes INSTALL a new steering wheel. REFER to Steering Column . No GO to C4. - C4 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-9 (Component Side) C2414D-7 (Component Side) C2414D-9 (Component Side) C2414D-8 (Component Side) C2414D-9
Is the voltage approximately 5 volts?
Yes INSTALL a new clockspring. REFER to Supplemental Restraint System . No GO to C5. - C5 CHECK FOR CORRECT SCCM OPERATION
- Disconnect all the SCCM connectors.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect all the SCCM connectors and make sure they are seated correctly.
- Connect all disconnected connectors.
- Install the driver air bag module. REFER to Supplemental Restraint System .
- 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.
