The memory seat module - driver receives voltage inputs from contacts inside the telescope switch. The memory seat module - driver then supplies battery voltage to the telescoping drive motor forward or reverse circuit depending on which direction of movement is requested. The motor is reversible and voltage is applied to either circuit to accomplish movement in opposite directions. The memory seat module - driver monitors the position and movement of the telescoping drive motor on the telescope signal circuit.

Ignition ON

The memory seat module - driver detects a switch input for more than 30 consecutive seconds after movement of the telescoping drive motor in the requested direction has stopped.

An intermittently stuck switch can cause this DTC to set. Also, the driver can cause this DTC to set by holding the telescope switch for 30 seconds after the column reaches the end of its travel.

Ignition ON, observe the scan tool Telescope Forward Switch and Telescope Rearward Switch parameters in the Driver Position Module Data Display. The reading should be Inactive for both parameters when the switch is not pressed.

1. Ignition OFF, disconnect the harness connector X2 at the memory seat module - driver.
2. Ignition OFF, test for less than 1 volt on both of the telescope switch signal circuits terminals A9 and A10.

⇒	If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the telescope switch.

3. If all circuits test normal, test or replace the memory seat module - driver.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
