Schematic Reference: Tilt/Telescoping Steering Column Schematics Connector End View Reference: Steering Wheel and Column Connector End Views DEFINITION: This table is for diagnosis of a telescoping steering column system in which the steering column will not telescope in or will not telescope out. | |||
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 | Observe the Column Position Fdbk parameter in the seat control module data display list with a scan tool. Is Column Position Fdbk between 0.1 and 4.9 volts? | Go to Step 4 | Go to Step 7 |
4 | Observe the Column Fore/Aft Switch parameter in the seat control module data display list while activating the telescoping actuator switch to the In and Out positions. Did the parameter change states as expected? | Go to Step 5 | Go to Step 6 |
5 |
Does the test lamp illuminate? | Go to Step 14 | Go to Step 10 |
6 |
Does the test lamp illuminate? | Go to Step 15 | Go to Step 9 |
7 |
Is the voltage 5 volts? | Go to Step 8 | Go to Step 11 |
8 |
Does the Column Position Fdbk change when you probe the circuit? | Go to Step 13 | Go to Step 11 |
9 | Test both of the column fore/aft switch In and Out signal and ground circuits for an open or short to voltage or ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 19 | Go to Step 12 |
10 | Test the steering column telescope motor forward and reverse circuits for an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 19 | Go to Step 15 |
11 | 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 an open or a short to voltage or ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 19 | Go to Step 15 |
12 | Inspect for poor connections at the harness connector of the telescoping actuator 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 19 | Go to Step 16 |
13 | Inspect for poor connections at the harness connector of the telescoping sensor. 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 19 | Go to Step 17 |
14 | Inspect for poor connections at the harness connector of the telescoping drive 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 19 | Go to Step 17 |
15 | Inspect for poor connections at the harness connector of the driver seat control module (SCM). 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 19 | Go to Step 18 |
16 | Replace the telescoping actuator switch. Refer to Telescope Actuator Switch Replacement . Did you complete the replacement? | Go to Step 19 | -- |
17 | Replace the telescoping drive motor. Refer to Telescope Actuator Assembly Replacement . Did you complete the replacement? | Go to Step 19 | -- |
18 |
Important: Perform the set up procedure for the seat control module. Replace the driver seat control module (SCM). Refer to Memory Seat Control Module Replacement in Seats. Did you complete the replacement? | Go to Step 19 | -- |
19 | Calibrate the steering column. Refer to Telescoping Steering Column Calibration . Did you complete the action? | Go to Step 20 | -- |
20 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 2 |
