Diagnostic Procedure
VTSS INDICATOR INOPERATIVE SYMPTOM CHART
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Disconnect the Instrument Panel Switch Pod connector. Measure the voltage of the Fused B+ circuit. Is the voltage above 10.0 volts? Yes --> Go To 2 No --> Repair the Fused B+ circuit for an open. Perform VTSS VERIFICATION TEST - 1A . |
All |
| 2 | Disconnect the Instrument Panel Switch Pod connector. Connect a voltmeter positive probe to a 12.0 volt supply and connect the ground probe to the VTSS Indicator Driver circuit at the I/P Switch Pod connector. Turn the ignition on. With the DRBIII® under BCM, actuate the VTSS Indicator lamp. Is the voltage above 10.0 volts when the VTSS Indicator lamp is actuated? Yes --> Replace the Instrument Panel Switch Pod assembly. Perform VTSS VERIFICATION TEST - 1A . No --> Go To 3 |
All |
| 3 | Disconnect the Instrument Panel Switch Pod connector. Disconnect the BCM C4 harness connector. Measure the resistance of the VTSS Indicator Driver circuit between the I/P Pod connector and the BCM C4 connector. Is the resistance below 5.0 ohms? Yes --> Replace and program the Body Control Module. Perform VTSS VERIFICATION TEST - 1A . No --> Repair the VTSS Indicator Driver circuit for an open. Perform VTSS VERIFICATION TEST - 1A . |
