Theory of Operation
When the handle switch is inactive, the voltage from the module to the switch will be 5.0 volts. When the switch is pressed, the voltage will be approximately 2.2 volts. This can be verified by using the scan tool and monitoring the handle switch states or voltage and pressing and releasing the liftgate handle.
Test Step 1 - DTC Present
- With the scan tool, record DTCs.
- Erase DTCs.
