BX ABS units
Posted: Tue Nov 03, 2009 7:21 pm
Hi,
Can anyone tell me exactly what the difference is between ABS units with green and purple stickers. I am aware that one is pre 09/89? (green) and purple stickered units are after this date and that units must match green/purpled stickered devices in the system.
My car had a purple stickered unit in it and the ABS light was suddenly comming on when self checking before startup some time ago. I checked everything and couldnt find a problem, on replacing the ABS unit with another purpled stickered unit the fault was still flagged. I tried another one and I got the same problem, I replaced the unit with a green stickered unit and the light flashes as normal in the self check and goes off after self check as it did before normally when it was working.
After a year or so I am not convinced that the ABS is working properly as I have never felt the distinctive vibrations through the pedal which was occasionally felt when braking in the wet etc. I know the ABS system appears to working in some way as I have still get the usual ABS light comming on when there has been a problem with the sensors, connectors etc and when driving at high speed with excessive road vibration (dodgy cable repair to a sensor).
Any idea of what the difference may be?. I am starting to suspect I have some earth problems with the car as I am seeing voltage drops/lights dim when operating certain electrics and my FM radio reception is not too hot now. I was thinking of getting hold of another purple stickered ABS unit and trying to diagnose the fault further.
regards
John
