1 | Did you perform the Diagnostic System Check - Vehicle? | Go to Step 2 | Go to Diagnostic System Check - Vehicle in Vehicle DTC Information |
2 | Verify that the tilt function is inoperative. Does the tilt function operate normally? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 |
Does the scan tool indicate the Idle state? | Go to Step 4 | Go to Step 6 |
4 | Observe the Telescope Tilt Switch parameter in the Tilt/Telescope Module Data Display list while activating the tilt/telescoping switch to the up and down positions with the scan tool. Did the parameter change states as expected? | Go to Step 5 | Go to Step 7 |
5 | Observe the Telescope Tilt Output parameter in the Tilt/Telescope Module Data Display list while activating the tilt/telescoping switch to the up and down positions with the scan tool. Did the parameter change states as expected? | Go to Step 8 | Go to Step 9 |
6 |
Does the scan tool indicate the Idle state? | Go to Step 10 | Go to Step 12 |
7 | Test both of the tilt/telescoping steering column switch up and down signal circuits for an open or short to voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 16 | Go to Step 9 |
8 | Test the steering column tilt actuator control circuits for a short to voltage or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 16 | Go to Step 11 |
9 | Test the tilt actuator position sensor 5 volt reference and ground circuits for an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 16 | Go to Step 12 |
10 | Inspect for poor connections at the harness connector of the tilt/telescoping steering column switch. 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 16 | Go to Step 13 |
11 | Inspect for poor connections at the harness connector of the tilt/telescoping steering column tilt motor. 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 16 | Go to Step 14 |
12 | Inspect for poor connections at the harness connector of the tilt/telescoping steering column control module. 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 16 | Go to Step 15 |
13 | Replace the tilt/telescope switch. Refer to Telescope Actuator Switch Replacement . Did you complete the replacement? | Go to Step 16 | -- |
14 | Replace the tilt motor. Refer to Tilt Motor Replacement . Did you complete the replacement? | Go to Step 16 | -- |
15 |
Important: Perform the set up procedure for the driver position module (DPM). Replace the DPM. Refer to Control Module References . Did you complete the replacement? | Go to Step 16 | -- |
16 | Calibrate the tilt/telescoping steering column. Refer to Telescoping Steering Column Calibration . Did you complete the action? | Go to Step 17 | -- |
17 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 2 |
