Step | Action | Value(s) | Yes | No |
|---|---|---|---|---|
Schematic Reference: Power Seats Schematics | ||||
1 | Did you review the power seat system operation and perform the necessary inspection? | -- | Go to Step 2 | Go to Symptoms - Seats |
2 | Verify that the Power Seat Inoperative complaint is present. Does the power seat system operate as described in the system description and operation? | -- | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 | Measure the voltage from the battery positive voltage (B+) circuit of the seat adjuster switch to a good ground. Does the voltage measure within the specified range? | 9-16 V | Go to Step 4 | Go to Step 6 |
4 | Measure the voltage from the battery positive voltage (B+) circuit of the seat adjuster switch to the ground circuit of the switch. Does the voltage measure within the specified range? | 9-16 V | Go to Step 5 | Go to Step 7 |
5 | Inspect for poor connections at the harness connector of the seat adjustor 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 9 | Go to Step 8 |
6 | Repair the short to ground or open in the battery positive voltage circuit of the seat adjuster switch. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | -- | Go to Step 9 | -- |
7 | Repair the open in the ground circuit of the seat adjuster switch. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | -- | Go to Step 9 | -- |
8 | Replace the seat adjuster switch. Refer to Power Seat Switch Replacement . Did you complete the replacement? | -- | Go to Step 9 | -- |
9 | Operate the system in order to verify the repair. Did you correct the condition? | -- | System OK | Go to Step 2 |
