For 1990-2009 cars

### Circuit Description

The driver position module (DPM) determines the position of the steering column based on inputs received from position sensor located in the tilt driver. The DPM supplies a 5-volt reference and a ground signal to the sensor and monitors the column position via a steering column sensor signal circuit.

### DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC B2880 Tilt Position Sensor

### Conditions for Running the DTC

DTC B1327 is not set as a current.

### Conditions for Setting the DTC

This DTC will set as current when the voltage is below 0.25 volt or greater than 4.75 volts for 2 seconds on the tilt driver signal circuit.

### Action Taken When the DTC Sets

The DPM will not allow the affected motor to work during memory recall and/or easy exit operations. However, the motor will still operate for manual switch positioning.

### Conditions for Clearing the DTC

This DTC will clear from current status when the voltage is greater than 0.25 or less than 4.75 volts for 2 seconds.

1. Turn OFF the ignition.
2. Disconnect the driver harness connector from the tilt/telescoping DPM.
3. Connect a 3-amp fused jumper wire between the tilt position circuit of the DPM and a good ground.
4. Turn ON the ignition, with the engine OFF.
5. With a DMM, observe the voltage on the tilt position signal input circuit.

Is the voltage less then the specified value?

0.12V
