The 4WS warning light indicates a problem with the 4 wheel steering system. Long blinks = 10, short blinks = 1. In other words, two long and two short blinks is a code 22. One long and one short is code 11.

The following self diagnosis will show any fault codes for the 4 wheel steering system:

  1. Remove the kick panel just beside accelerator pedal.
  2. Locate blue wires.
  3. Locate black connector. Hold it so that the notch is up.
  4. With ignition off, insert one (either one) of the blue wires into top row, 4th pin from left. (The black connector has 4 pins in the top row and six in the bottom row)
  5. Turn key to on position, but do not start the car.
  6. Watch flashing 4WS light on dashboard. Count blinks. Long blinks = 10, Short blinks = 1.

To clear existing codes:

  1. Ignition 'OFF'
  2. Remove Fuse SBF7 (4WS) from Fuse Box in Engine Bay. Wait 5 minutes.
  3. Reinsert fuse.
  4. Recheck as above to ensure all codes have been cleared. No codes = steady blinks at 1/4 second intervals.
