Vehicle towed in. Checked codes and found code '81 imobiliser on EWS2'. Fault stored and present.
No spark at plugs. Fuel pump not working. Carried out few checks. Fuel pump will work if earth added. Crank shaft sensor scoped from ECU and is working.
When vehicle is locked, imobiliser light flashes. When unlocked, light is out.
Have disconnected battery to try to reset alarm.
Can anybody give any tips on how to test alarm, or are these alarm systems problematic - would it be better to send to dealer?
