20 Most Recent Infinity 50.5CS Car Speaker Questions & Answers

Its possible that your ptoblem isn't in the ECU/PCM, so, the Inmobilizer Module go to bad...

This includes all Rover or Honda petrol engines, Peugeot or Rover Diesel engines, the older square shaped and the newer bubble shape.

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 down, 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.


Programming Lucas Key Fobs
When programming new key fobs, all key fobs are automatically erased from the ECU control box fitted to the vehicle. This is done because if you have lost a key fob or had a key fob stolen, the lost or stolen key fob will no longer work on your vehicle. At the time of programming all key fobs you need to work with the vehicle must be programmed.

The Rover 200 immobiliser system can have up to 4 key fobs programmed. At Remote key Ltd if a new alarm ECU control box or a new engine management ECU control box is required, they will need programming together before your vehicle will start. At Remote key Ltd we can carry out all the programming required, all this can be done on or off the vehicle.

Range/Distance Problems
Does you key fob not operate very far from your vehicle?
This can be caused by many factors. As we use more wireless electronic products, the radio waves interfere with each other and this is the most common problem when your remote key fob loses its range from your vehicle.

Your Rover 200 relies on the remote key fob to start, get a spare. The remote key fobs get a hard life, they get dropped, damp, wet, hot, cold, we sit on them, when the remote will not operate, the problem will probably be the remote key fob.

If you disconnected the battery, its big possible that the "inmobilizer" system is armed; if this system is bad, you need to take the car to a Rover Dealer for it be done (to re-match ECU/PCM to 5AS Inmobilizer Module), there is no other way

The most common cause of this is the capacitors in the crossover network fail and cause all the wattage to go to that speaker.
