Location of immobiliser ECU control box.
Look above the pedals.
Rovers built before September 1995 on “L”, “M” and early “N” suffered from key fobs losing the code, this can be rectified with a software update on the vehicle. The Rover 200 Immobiliser system is very reliable, the ECU control rarely fails, if your vehicle will not start it is probably due to the remote key fob. You may have to perform the above sequence if your vehicles battery has gone flat or it is disconnected.
The Rover remote key fob uses a rolling code system. When you press the key fob, the code changes every time, and the alarm box in your vehicle also changes its code to match with the key fob. This is a great antitheft system but sometimes the key fob and alarm box codes do not match and the system will not operate.
The most common cause for this is pressing the buttons on the key fob away from the vehicle, the key fob code moves on but the alarm box on the vehicle does not, so the two codes do not match. The key fobs and the ECU control box receiver on your vehicle have a clock, this clock also moves the code even if the key fob is not used.
- ECU – Electronic control unit, the box which controls the alarm, immobiliser and usually the central locking fitted to your vehicle, the immobiliser ECU is a separate unit under the dashboard.
- EKA – Emergency key access, this number has no connection to the remote key fob.
- MHZ – megahertz (frequency number).
- ARMED – this is when you have locked your vehicle with the key fob, the alarm system is active and the immobiliser is on.
- DISARMED – this is when you have unlocked your vehicle with the key fob, the alarm system is not active and the immobiliser is off.
The image on the right is the inside of the key fob, the most common problem when the key fob fails is the component circled. Very carefully check to see if the 2 wire legs are attached to the component and the circuit board.
