Schematic Reference: Tilt/Telescoping Steering Column Schematics DEFINITION: This table is for a telescoping steering column system in which the telescope functions are inoperative. | |||
1 | Did you perform the Steering Wheel and Column Diagnostic System Check? | 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 in Wiring Systems | Go to Step 3 |
3 |
Did the parameter change states as expected? | Go to Step 4 | Go to Step 5 |
4 | With the scan tool, observe the column feedback parameter in the seat control module data display list while activating the column fore/aft switch to the In and Out positions. Did the parameter change states? | Go to Step 7 | Go to Step 6 |
5 | Test both of the column fore/aft switch In and Out signal and ground 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 14 | Go to Step 8 |
6 | Test the steering column telescope actuator control circuits for an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 14 | Go to Step 9 |
7 | Test the 5 volt reference and memory seat/mirror sensor low reference circuits for an open and the steering column telescope motor signal circuit for a short to voltage . Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 14 | Go to Step 10 |
8 | Inspect for poor connections at the harness connector of the column fore/aft 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 14 | Go to Step 11 |
9 | 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 14 | Go to Step 12 |
10 | Inspect for poor connections at the harness connector of the seat 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 14 | Go to Step 13 |
11 | Replace the column fore/aft switch. Refer to Telescope Actuator Switch Replacement - On Vehicle . Did you complete the replacement? | Go to Step 14 | -- |
12 | Replace the telescope actuator. Refer to Telescope Actuator Assembly Replacement - On Vehicle . Did you complete the replacement? | Go to Step 14 | -- |
13 |
Important: Perform the set up procedure for the seat control module. Replace the seat control module. Refer to Memory Seat Control Module Replacement in Seats. Did you complete the replacement? | Go to Step 14 | -- |
14 | Perform the steering column control module programming. Refer to Telescoping Steering Column Calibration . Did you complete the action? | Go to Step 15 | -- |
15 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 2 |
