Clearing the fault code

Clearing the fault code

Once a fault has been rectified, the ECU memory must be cleared in the following way;

1. Remove the Y/G to B bridging wire and refit

bridging connector.

2. Turn starter switch ON
3. Wait for warning light in the instrument pack to

extinguish

4. Turn starter switch OFF
5. Repeat procedure 20 times.

NOTE: If the memory has been cleared successfully the start identification code ’1-2’ will continually flash until the Y/G to B wires are bridged again.

Ensure the bridging connector is refitted when the system check has been completed.

Before replacing components

Before replacing major components like the ECU or modulators ensure that a thorough diagnosis of the fault has been carried out. Failure of these components is rare. Usually a fault lies within the associated wiring or connections to the component and not the component itself. Ensure that the fault code memory is cleared so that if any further problems occur, the fault codes stored in the memory relate to the current problem and not a previously repaired fault.

NOTE: Fault could be in the specific component or in the associated wiring.
