Pinpoint Test D : The Steering Column Operates In Two Second Intervals When Using The Steering Column Control Switch (Jog Mode)
NOTE:
Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
- D1 CHECK IF THE STEERING COLUMN POWER FEATURE IS IN JOG MODE
- Operate the steering column power tilt feature in both directions (up/down).
Is the steering column tilt feature operating in jog mode?
Yes GO to D2 No GO to D3 - D2 CHECK THE TILT MOTOR SENSOR CIRCUITS FOR AN OPEN
- Ignition OFF.
- Disconnect DSM C341A .
- Disconnect DSM C341F .
- Disconnect Steering Column Tilt Motor C2600 .
- Measure:
Positive Lead Measurement / Action Negative Lead C2600-4 C341A-13 Positive Lead Measurement / Action Negative Lead C2600-3 C341F-9
Are the resistances less than 3 ohms?
Yes 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 D4 No REPAIR the circuit in question. - D3 CHECK THE TELESCOPE MOTOR SENSOR CIRCUITS FOR AN OPEN
- Ignition OFF.
- Disconnect DSM C341A .
- Disconnect DSM C341F .
- Disconnect Steering Column Telescope Motor C2601 .
- Measure:
Positive Lead Measurement / Action Negative Lead C2601-2 C341A-12 Positive Lead Measurement / Action Negative Lead C2601-4 C341F-9
Are the resistances less than 3 ohms?
Yes INSTALL a new steering column. REFER to: Steering Column . TEST the system for normal operation. If the concern is still present, GO to D4 No REPAIR the circuit in question. - D4 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.
