Malfunction codes can be retrieved from the engine, ABS, automatic transmission, Cruise Control, 4WS and air-bag computers by reading the codes flashed by the LED.
Engine Malfunction Codes
Engine
codes can be read by connecting the TEN and GND pins,
using the jumper wire. (See above for the location of this pin) and The LED
connected to B+ and FEN pins. The codes are read by counting the number of flashes
given out from the LED. The RED lead goes to
the B+ pin
BE CAREFUL CONNECTING THE B+ PIN... this is a live 30A feed
The
first series of long flashes (1.2 Secs) are the tens position. There is a short
pause (1.6 Secs) and then the second series of quick flashes (0.4 Secs) begins
which are the digits. The codes are repeated indefinitely.
Example: ------ ------ (2) -- -- -- (3) is 23 – RH 02 Sensor
