kslb Posted April 19, 2010 Share Posted April 19, 2010 The ABS warning light does not come on with the other warning lights on my dads NA. I have tested the bulb and that is fine and am now a bit stumped! Any ideas? The ABS is working fine it is just the warning light on start up that does not come on. Any help much appreciated.

w41k3r Posted April 19, 2010 Share Posted April 19, 2010 It will no doubt be dry solder mine does the same sometimes the lights light up other times they dont wiggle the wires at the back and see if its that then re solder Quote Link to comment Share on other sites More sharing options...
Homer Posted April 19, 2010 Share Posted April 19, 2010 Dry solder joins on the illumination unit Keith, very, very common. Remove the unit and split it open to reveal the two curcuit boards, then retouch the joints between the two with a very hot soldering iron. Done it a dozen times now with older supra's Quote Link to comment Share on other sites More sharing options...

kslb Posted April 20, 2010 Author Share Posted April 20, 2010 No luck! Tried redoing the solders and even traced contnuity back to the ABS ecu. Any more ideas? Quote Link to comment Share on other sites More sharing options...
kslb Posted April 22, 2010 Author Share Posted April 22, 2010 Had to bridge the gap between the engine management light and the ABS light on the circuit board with a bit of solder,should get it through the MOT and then back to tracing the problem!

Tim_v_M Posted May 8, 2010 Share Posted May 8, 2010 Same problem here! My car even failed the Dutch MOT (APK) because the ABS light doesn't work [ANGRY][/ANGRY] Only thing, I have no idea where the light should be, and how I get to the bulb. Does it have to be the most left light in the row with the lights when you're doors are open etc? Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted July 28, 2013 Share Posted July 28, 2013 Sorry for bumping this old thread.. Was this problem ever solved? I am trying to troubleshoot a car with the same issue (In addition the cruise control light is not coming on also). ABS works, the warning light cluster works (swapped into my car), tried a working cluster in the problem car, not working also.. Looking for some advice on what to check...

Iky Posted July 29, 2013 Share Posted July 29, 2013 Common problem it seems. http://mkiv.com/techarticles/trac_off_mil_odo/index.html There MUST be a dodgy connector pin / wire or broken track / faulty component on the board. Check it fully with a multimeter. Quote Link to comment Share on other sites More sharing options...

Iky Posted July 29, 2013 Share Posted July 29, 2013 Suppose, only option is to trace all the wires back. Is there some sort of ABS diagnostics in the shop manual? Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted July 30, 2013 Share Posted July 30, 2013 There is a circuit diagram for the warning lamp, need to sit with a meter and test each part of the circuit I suppose.. Quote Link to comment Share on other sites More sharing options...
