Schematic Reference: Tilt/Telescoping Steering Column Schematics Connector End View Reference: Component Connector End Views DEFINITION: Tilt function is Inoperative, but telescope function operates normally.
1 | Did you perform the Diagnostic System Check - Vehicle? | Go to Step 2 | Go to Diagnostic System Check - Vehicle
2 | Verify that the steering column tilt function is inoperative. Does the tilt motor operate normally? | Go to Testing for Intermittent Conditions and Poor Connections | Go to Step 3
3 |

1. Turn ON the ignition, with the engine OFF.
2. With the scan tool, detect telescope/tilt switch parameter in the tilt/telescope module data display list.

Does the scan tool display the idle state?

Go to Step 4

Go to Step 6

4 | When tilt/telescoping manual switch moves up/down from neutral position, observe tilt/telescoping switch parameter on tilt/telescoping module data display list. Did the parameter change as expected? | Go to Step 5 | Go to Step 7
5 | When tilt/telescoping manual switch moves up/down from neutral position, observe tilt/telescoping output parameter on tilt/telescoping module data display list. Did the parameter change as expected? | Go to Step 8 | Go to Step 9
6 |

1. Turn OFF the ignition.
2. Disconnect the steering column tilt/telescope switch harness connector.

Does the scan tool display the idle state?
