Schematic Reference: Tilt/Telescoping Steering Column Schematics Connector End View References: Steering Wheel and Column Connector End Views , Power Seat Connector End Views DEFINITION: The telescope function is inoperative but the tilt function operates. | |||
1 | Did you perform the Diagnostic System Check - Vehicle? | Go to Step 2 | |
2 | Verify that the telescoping function is inoperative. Does the telescoping function operate normally? | Go to Testing for Intermittent Conditions and Poor Connections | Go to Step 3 |
3 |
Does the scan tool indicate either switch is Active? | Go to Step 6 | Go to Step 4 |
4 | Observe the Telescope Forward Switch and the Telescope Rearward Switch parameters while pressing the tilt/telescoping switch to the Forward and Rearward positions. Did both parameters change states as expected? | Go to Step 5 | Go to Step 7 |
5 | Observe the Telescope Forward Command and the Telescope Rearward Command parameters in the Memory Seat Module data list while pressing the tilt/telescoping switch to the In and Out positions. Did both parameters change states as expected? | Go to Step 8 | Go to Step 9 |
6 |
Does the scan tool indicate the Telescope Forward Switch and the Telescope Rearward Switch parameters are both Inactive? | Go to Step 10 | Go to Step 7 |
7 | Test the telescoping steering column switch In and Out signal circuits for an open or short to voltage. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? | Go to Step 18 | Go to Step 17 |
8 | Test the steering column telescope motor control - forward circuit and the steering column telescope motor control - reverse circuit for a short to voltage or an open. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? | Go to Step 18 | Go to Step 11 |
9 | Test the telescope actuator position sensor signal, 5-volt reference, and ground circuits for an open. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? | Go to Step 18 | 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 . Did you find and correct the condition? | Go to Step 18 | Go to Step 14 |
11 | Inspect for poor connections at the harness connector of the tilt/telescoping steering column telescope actuator. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition? | Go to Step 18 | Go to Step 13 |
12 | Inspect for poor connections at the harness connector of the memory seat module (MSM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition? | Go to Step 18 | Go to Step 16 |
13 |
Did you correct the condition? | Go to Step 18 | Go to Step 15 |
14 | Replace the tilt/telescope switch. Did you complete the replacement? | Go to Step 18 | -- |
15 | Replace the telescope actuator. Refer to Telescope Actuator Assembly Replacement . Did you complete the replacement? | Go to Step 17 | -- |
16 |
Important: Perform the set up procedure for the MSM. Replace the MSM. Refer to Control Module References . Did you complete the replacement? | Go to Step 18 | -- |
17 | Replace the IPM. Refer to Control Module References . Did you complete the replacement? | Go to Step 18 | -- |
18 | Perform the steering column calibration. Refer to Telescoping Steering Column Calibration . Did you complete the action? | Go to Step 19 | -- |
19 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 2 |
