Circuit Description
The steering column module determines the tilt position of the steering column based on the following factors:
| • | Inputs received from the tilt position sensor that is built into the telescope actuator |
| • | The telescoping actuator |
The Steering column module supplies a 5-volt reference and ground to the tilt position sensor while also monitoring the column position form the telescope position signal circuit.
Conditions for Running the DTC
DTC B1327 is not set as current.
Conditions for Setting the DTC
The DTC sets as current when the voltage at the steering column tilt motor signal is less than 4.8 volts for 2 seconds on the tilt circuit.
Action Taken When the DTC Sets
The steering column module 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 0.12 volts for 2 seconds. |
| • | Use a scan tool. |
Step | Action | Value(s) | Yes | No |
