I have just made myself a code reader to trouble shoot an ASD light on problem on a 300CE 24v. I got code 4 (4 flashes )from pin 5 and I have now reset the fault and the light has stayed off. Can some one pleae tell me what fault ASD code 4 is and also now that I have the reader, a chart of all the codes for all the systems would be appreciated.

Code 4 is the LF ABS speed sensor.

Hi,
I have some ASD-codes here for years 91-93:

1: No fault in system
2: ASD control module (N30/2)
3: Stop Lamp Switch (S9/1)
4: Left Front Axial Vehicle speed sensor (L6/1)
5: Right Front Axial Vehicle speed sensor (L6/2)
6: Rear Axial speed sensor (L6)
7: No speed signal from Any sensor (L6,L6/1,L6/2), missing ground
8: ASD valve(Y38) or Stop Lamp Switch (S9/1)

Regards.

Thomas
