Pinpoint Test E: Vehicle Electrical System Test
- Test 5 Lock Command
Disconnect electrical connector from latch
Close all vehicle doors apart from door being investigated, please note which door, left side or right side is under investigation
Monitor the circuit for momentary power when locking the vehicle via the key-fob or smart key between terminals 1 and 10 left side or 8 and 10 right side
Is there momentary power (for approx 8 seconds) between terminals 1 and 10 left side or 8 and 10 right side when locking the vehicle via the key-fob or smart key
YES: The vehicle electrical system is locking correctly, providing the signal to the latch. Go to step 2.
NO: Refer to the electrical circuit diagrams and investigate why vehicle electrical system is not providing signals to the latch. Using the manufacturer approved diagnostic system check for logged DTCs to localize the fault
- Test 6 Unlock Command
Monitor the circuit for momentary power when unlocking the vehicle via the key-fob between terminals 1 and 9 left side or 8 and 9 right side
Is there momentary power (for approx 8 seconds) between terminals 1 and 9 left side and 8 and 9 right side when unlocking the vehicle via the key-fob
YES: The vehicle electrical system is unlocking correctly, providing the signal to the latch. Plug electrical connector back in to latch. Rebuild vehicle and check for correct operation
NO: Refer to the electrical circuit diagrams and investigate why vehicle electrical system is not providing signals to the latch. Using the manufacturer approved diagnostic system check for logged DTCs to localize the fault
