ABS and TCS light on, I've tried pulling codes by jumping gnd and tbs, also gnd and ten but nether the ABS nor engine light flashes with ignition on?
I even tried removing battery wire for 10 mins?

Does anyone have any experience of this issue or a wiring diagram for both ABS and diagnostic port?
many thanks

 

Do we not have anyone with OBD1 experience or archived wiring diagrams on this forum??

 

I have experience with Fords Star tester ( aka T bone )

Have you tried hooking up a scan tool?

 

No, I don't have a scan tool.
Does anyone have wiring diagrams for 1999 mazda 626?​​​​​

 

Hi and thanks to those that did respond to my message, albeit with no actual useful information apart from connecting a scan tool.
As I mentioned in my original query, I jumped both gnd and tbs, also gnd and ten and couldn't pull any codes. So no amount of connecting different scan
tools was going to help.
I would have been very happy to pay for correct wiring diagrams, but after many many hours of searching I couldn't find anything suitable.

In the end, I testing every wheel speed sensor and identified one that had a very high resistance compared to the others, so I replaced this and the ABS light went out.

 

Hello, wish I was able to provide this sooner, but I'm almost not active in this forum at all.
Sadly mazda626.net is no longer operational, as it had a bunch of good stuff.
I will give you this however: https://www.cardiagnostics.be/-now/M...%20reading.htm
It's by no means perfect, but it's a great start for future debugging.
When decoding flashes, long blinks is double digits (10, 20, 30 etc), and short blinks is single digits (1, 2, 3 etc).
Hope this will be useful, albeit a little late for your abs sensor (they are kinda prone to dying when reaching this age)
