NWDSdax 10 Posted January 20, 2019 My corrado 1994 vr6 ABS isn’t working! Scanning it brings up 4 codes 00259 Abs inlet valve front right (N99) 00276 Abs outlet valve left rear (N136) 00532 Supply voltage B+ static-no indication on display 00283 Front left Abs speed sensor (G47) static-no indication on display Any body shed any light on them? I’m assuming a speed sensor and pump probably? Do have a spare I can send off to be refurbished Thanks in advance Quote Share this post Link to post Share on other sites
seanl82 23 Posted January 20, 2019 Have you cleared the codes from within the specific abs test then tried again? I was chasing codes that weren't there as they don't clear when resetting DTCs. But if so, yeah with the inlet and outlet ports it definitely sounds like your pump. Quote Share this post Link to post Share on other sites
NWDSdax 10 Posted January 20, 2019 I did clear them with my code reader and they came back immediately. Quote Share this post Link to post Share on other sites
Dox 23 Posted January 20, 2019 The wiring should just be long enough to unplug and reconnect to your spare unit, then you can scan again Quote Share this post Link to post Share on other sites
NWDSdax 10 Posted January 20, 2019 The spare unit is faulty also! But I can send that one off to be repaired, then once it detours just a matter of swapping them over rather than leaving one of the car and waiting for it to return fixed before I can fit it.

dr_mat 0 Posted January 20, 2019 Don't know whether it was a coincidence but my abs unit went shortly after the car spent a day in the oven after some paintwork got done. But yes. You have a faulty abs pump unit...! Quote Share this post Link to post Share on other sites

As I understand it spares are unavailable for the pumps, BBA cannibalise old units and reflow the solder joints to produce a Frankenstein, so there's no guarantee they can repair either of your units.

dr_mat 0 Posted January 20, 2019 They are usually very reliable, I've no doubt the supply of working valves will not disappear for a while. Quote Share this post Link to post Share on other sites
Dox 23 Posted January 20, 2019 They are usually very reliable, I've no doubt the supply of working valves will not disappear for a while. There are people on this forum who've had there units returned to them after being charged the initial testing fee and the units deemed unrepairable. BBA are doing their best, ultimately it will depend on how many used spares they can get hold of and how profitable the repair is Quote Share this post Link to post Share on other sites

I suppose it depends what was wrong with it ultimately. As you say they can't get new parts. Quote Share this post Link to post Share on other sites
seanl82 23 Posted January 21, 2019 From what I've heard, the valves can be replaced but the send back unrepairable units if there is physical damage either internally or externally, as they can't guarantee it. Quote Share this post Link to post Share on other sites
