1 | Did you perform the Diagnostic System Check-Vehicle? | Go to Step 2 | |
2 | Verify the fault is present. Does the system operate normally? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 | Check the battery voltage. Refer to Measuring Voltage in Wiring Systems. Is the battery voltage more than 11.5 volts? | Go to Step 4 | Go to Battery Inspection/Test in Engine Electrical |
4 | Check the battery voltage supply circuit to the seat modules with a test lamp connected to a known good ground. Refer to Measuring Voltage in Wiring Systems. Does the test lamp illuminate? | Go to Step 5 | Go to Step 6 |
5 | Ensure all seat ground points are secure and have good contact with the vehicle structure. Are all the ground points secure to the vehicle with good contact? | Go to Step 7 | Go to Step 8 |
6 | Repair an open in the battery voltage supply circuit between the vehicle battery and the seat modules. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 9 | -- |
7 | Repair and open in the seat module ground circuit. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 9 | -- |
8 | Tighten all ground points. Did you complete the repair? | Go to Step 9 | -- |
9 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 3 |
