Question about 1999 Daewoo Lanos
Can u help me to find what is the meaning of code NO.12 for daewoo racer using a jumper wire i found this code
Code 12 in fact is NOTHING... Is the START OF THE DIAGNOSTIC.
You can see the code 12 as normal, because when code 12 is showed, is MODE DIAGNOSTIC ON.
If you have another code after 12, THIS IS a real fault code.
But if only code 12 is showed, no faults codes exists!.
The procedure is:
- Shortcircuit A + B in ECU
- Turn ON key (but not start engine)
- Check Engine light is showing code 12... ENGINE LAMP TURN ON SHORT TIME ONCE... PAUSE... ENGINE LAMP TURNO ON SHORT TIME TWICE... PAUSE...
- If there is a fault, the fault code is showed AFTER the code 12... and then repeat in a loop.
Example: If code 34 (Low voltage MAP) exists, the secuence will be:
1,2,PAUSE, 3,4, PAUSE... 1,2,PAUSE,3,4,PAUSE... in a eternal loop.
