- The following conditions may cause an intermittent malfunction.
- There is an intermittent short to ground in the steering column telescope reverse switch signal circuit.
- The steering column switch is shorted to ground internally or is sticking.
- The steering column switch was closed for longer than 20 seconds.
- If the steering column telescope reverse switch signal circuit is shorted to ground or the steering column switch is stuck closed, the steering column will remain in the full out position at all times.
- Using a scan tool, select scan tool inputs and monitor steering column switch status. If the scan tool displays Out, disconnect the steering column switch. If the display changes to Idle, replace the switch. If the scan tool still displays Out, check steering column telescope reverse switch signal circuit for a short to ground.
- If the DTC does not reset after the code is cleared, then the problem may be intermittent. Perform the tests shown while moving related wiring and connectors. This can often cause the malfunction to occur. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
- Activate the steering column switch numerous times while monitoring the status on the scan tool to see if it sticks intermittently.
