After starting the engine, the warning lamp "check engine" should go out. If the light stays on after starting the engine, there is a problem with the electronic system.
1. To determine fault codes, check that the battery is fully charged, the throttle is fully closed, the transmission is in neutral, all electrical consumers are off and the engine is warm to operating temperature.
2. Turn on the ignition, but do not start the engine.
3. Using an additional wire, connect the contacts TE1 and E1 of the control connector.
4. The fault code is determined by the number of flashes of the light bulb. The first digit of the code is determined by the number of flashes of the light, then after a pause, the second digit of the code is determined by the number of flashes of the light. For example, code 24. The lamp will blink 2 times, then after a pause 4 more times.
5. If several malfunctions are recorded in the memory of the electronic unit, they will be displayed in turn.
6. To erase a stored fault code from memory, remove the 15A EFI fuse for at least 10 seconds with the ignition off.
7. The fault code can also be erased by removing the ground wire from the battery.
