Testing / Fault Finding
If central locking fails to operate:
1. Check remote control ‘LED’ does come on, does the alarm arm / disarm? (Indicators flashing signify alarm setting) If answer Yes - Try test No. 2 If answer No - Check internal battery, replace if necessary. If still not arming / disarming, Call PHH to organise alarm engineer. 2. Does the vehicle centrally lock using the key in the drivers door? If answer is Yes - Problem is likely to be an alarm fault. If answer is No - Problem is likely to be a vehicle fault. 3. Technicians only:
As a final test, if the 2 x interface wires are removed from the vehicle wiring loom i.e. Grey / Black, Brown / Black removed from Brown / White. This will prove if fault is alarm or vehicle related.
