The codes are indicated by the number of both red and green lamps. First the red lamp flashes and then the green one. The red lamp correspond to units of ten and the green lamp to units of one. For example, when the red lamp flashes once and the green lamp flashs twice, this signifies the number "12".

The codes are:
11 Crank angle sensor circuit
12 Air flow meter circuit
13 Engine temperature sensor circuit
14 Vehicle speed sensor circuit
21 Ignition signal missing in primary coil
31 E.C.U. (E.C.C.S. control unit)
32* EGR function
33 Exhaust gas O2 sensor circuit
35* Exhaust gas temperature circuit
43 Throttle position sensor circuit
45* Injector leak
55 No malfunction
