Circuit Description
The steering column module determines the position of the steering column based on inputs received from position sensors that are built into the tilt actuator and the telescoping actuator. The steering column module supplies a 5 volt reference and a ground to these sensors and monitors the column position via a tilt position signal circuit and a telescope position signal circuit.
Conditions for Running the DTC
DTC B1327 is not set as current.
Conditions for Setting the DTC
This DTC will set as current when the voltage is greater than 4.8 volts for 2 seconds.
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 less than 4.8 volts for 2 seconds. |
| • | Use the ON-Board clearing DTCs feature. |
| • | Use a scan tool. |
Diagnostic Aids
Inspect the steering column for abnormal looseness.
Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
1 | Did you perform the Tilt/Telescoping Steering Column Diagnostic System Check? | -- | Go to Step 2 | Go to Tilt/Telescoping Steering Column Diagnostic System Check |
2 |
Does the scan tool indicate that the Telescope Sensor parameter is less than the specified value? | 4.8 volts | Go to Diagnostic Aids | Go to Step 3 |
3 |
Does the scan tool indicate that the Telescope Sensor parameter is less than the specified value? | 0.12 volts | Go to Step 4 | Go to Step 6 |
4 | Inspect for poor connections at the harness connector of the telescope actuator. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 7 | Go to Step 5 |
