Telescopic Position Sensor Circuit
- Remove tilt and telescopic control module. Remove telescopic position sensor with harness connector still connected. Manually slide telescopic position sensor lever to fully extended position. Measure voltage between tilt and telescopic control module connector T10, terminals No. 5 and No. 6. See Figure.
- Manually slide telescopic position sensor lever to fully retracted position. Voltage should increase as lever is moved from extended position to retracted position. If voltage is 4-5 volts with lever in fully retracted position and operation is as specified, go to TROUBLE SHOOTING and identify next circuit to be checked. If voltage not is 4-5 volts with lever in fully retracted position or operation is not as specified, go to next step.
- Disconnect telescopic position sensor connector. Manually slide telescopic position sensor lever to fully extended position. Measure resistance between telescopic position sensor connector terminals No. 3 and No. 6. See Fig 1. If resistance is 5000 ohms, go to next step. If resistance is not 5000 ohms, replace telescopic position sensor and recheck system.
- Manually slide telescopic position sensor lever to fully extended position. Resistance should increase as lever is moved from fully extended to fully retracted position. Measure resistance between telescopic position sensor connector terminals No. 3 and No. 5. If resistance is 4000-5000 ohms in fully retracted position and operation is as specified, go to next step. If resistance is not 4000-5000 ohms in fully retracted position or operation is not as specified, replace tilt position sensor and recheck system.
- Check and repair wiring harness and connectors between tilt and telescopic control module and telescopic position sensor connector. If wiring harness and connectors are okay, replace tilt and telescopic control module and recheck system.
