Pinpoint Test A : The Steering Column Power Tilt Feature Is Inoperative Using The Steering Column Control Switch
NOTE:
Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
- A1 CHECK THE COMMUNICATION NETWORK
- Ignition ON.
- Using a diagnostic scan tool, carry out the network test.
Does the GWM, the SCCM and the DSM pass the network test?
Yes GO to A2 No REFER to: Communications Network - 2.0L Duratec - Hybrid (96kW/130PS) . - A2 CHECK FOR SCCM (STEERING COLUMN CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, carry out the SCCM self-test.
Are any Diagnostic Trouble Codes (DTCs) present?
Yes REFER to SCCM DTC Chart . No GO to A3 - A3 CHECK THE SCCM (STEERING COLUMN CONTROL MODULE) STEERING COLUMN ADJUST SWITCH (STRCOL_ADJ) PID (PARAMETER IDENTIFICATION)
- Using a diagnostic scan tool, view the SCCM Parameter Identifications (PIDs).
- Using a diagnostic scan tool, monitor the SCCM STRCOL_ADJ PID while activating the steering column control switch in the up and down directions.
Does the PID display match the steering column control switch positions?
Yes GO to A4 No INSTALL a new steering column control switch. TEST the system for normal operation. If the concern is still present, GO to A9 - A4 CHECK THE STEERING COLUMN TILT MOTOR CIRCUITS FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect DSM C341F .
- Disconnect Steering Column Tilt Motor C2600 .
- Ignition ON.
Is any voltage present?
Yes REPAIR the circuit in question. No GO to A5 - A5 CHECK THE STEERING COLUMN TILT MOTOR CIRCUITS FOR A SHORT TO GROUND
- Ignition OFF.
Are the resistances greater than 10, 000 ohms?
Yes GO to A6 No REPAIR the circuit in question. - A6 CHECK THE STEERING COLUMN TILT MOTOR CIRCUITS FOR AN OPEN
Are the resistances less than 3 ohms?
Yes GO to A7 No REPAIR the circuit in question. - A7 CHECK THE STEERING COLUMN TILT MOTOR OPERATION
- Remove the steering column tilt motor. REFER to: Steering Column Tilt Motor .
- Connect DSM C341F .
- Connect Steering Column Tilt Motor C2600 .
- Ignition ON.
- Activate the steering column tilt feature using the steering column control switch.
Does the tilt motor activate when using the steering column control switch?
Yes INSTALL a new steering column. REFER to: Steering Column . No INSTALL a new steering column tilt motor. REFER to: Steering Column Tilt Motor . TEST the system for normal operation. If the concern is still present, GO to A8 - A8 CHECK FOR CORRECT DSM (DRIVER FRONT SEAT MODULE) OPERATION
- Disconnect and inspect all the DSM connectors.
- Repair:
- corrosion (install new connectors or terminals - clean module pins)
- damaged or bent pins - install new terminals pins
- pushed-out pins - install new pins as necessary
- Reconnect the DSM connectors and 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 TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new DSM. REFER to: Driver Front Seat Module (DSM) . 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. - A9 CHECK FOR CORRECT SCCM (STEERING COLUMN CONTROL MODULE) OPERATION
- Disconnect and inspect all the SCCM connectors.
- Repair:
- corrosion (install new connectors or terminals - clean module pins)
- damaged or bent pins - install new terminals pins
- pushed-out pins - install new pins as necessary
- Reconnect the SCCM connectors and 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 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 module connections. ADDRESS the root cause of any connector or pin issues.
