ECU diagnostic
Switch on the ignition, but don't start. The LED on the ECU will be glowing.
Turn the selector screw clockwise all the way (gently!) If your ECU doesn't have a diagnostic mode screw, use the diagnostic connector to enter the diagnostics mode.
For one LED ECU's: wait a couple of seconds, and turn the screw back counter-clockwise, the ECU is now in mode 2.
Note - the engine check light on the dash will mirror the LED on the computer.
The ECU's on most R32's have one LED, long flash = first digit, short flash = second digit, eg long, long, short = code 21.
Codes:
11 Crankshaft position sensor
12 MAF sensor circuit
13 Coolent temperature circuit
14 Vehicle speed sensor circuit
21 Ignition circuit
31 ECU
34 Knock sensor
43 Throttle position circuit
45 Injector leak
51 Ignition circuit
54 Auto signal to ECU
55 All OK
Turn the ignition off to put the ECU back to normal.
Is this correct? I have never done this before.
Thanks,
Scott
