I drove our Saab 9-3 sports estate (2006) this week only to get an ABS error not long after leaving home, and a grinding noise when applying the brakes, (ABS kicking in) it was very intermittent and the speedo I could tell was registering an incorrect speed, after a few miles it pinged a bigger warning and the mainABS malfunction message appeared, now the brakes fine because ABS switched itself off. I've replaced all four wheel bearing earlier this year including finding a break in an ABS wire in a rear wheel so am somewhat disappointed
I plugged in an opcom reader today and got these errors:
co274 Isolation Time Range/performance
(59) - Not present
C0035 - Front Left Wheel Speed sensor range/performance
(2A) - Not present
So I removed the front wheel and had look at the wires , the seem fine, in fact it's only a few inches of covered wires so much less for the elements to attack, the connector looked fine, so I tried to measure the speed sensor, if I put the multi meter on it set to ac voltage I get nothin when I spin the wheel disk, but it's so hard to spin I'm wondering maybe I'm not turning it fast enough?
I set it to ohms and get a reading of .416, I couldn't find if this is right or not.
I've attached some pics, please can anyone help advise on what to do next?
Am really short of cash & can't take it to the garage, I thought I'd sorted it, my biggest fear is the new wheel hub bearing has failed , it was a night mare changing these things, I got the parts from Eurocar parts, so I suppose they will cover the part but I'll still have to do all the work.
Appreciate any help..
For now I've pulled fuse 33, the main ABS error is now gone but I can see the icon light up on the dash and a triangle warning light. But now the speedo isn't working at all, so I'm wondering if the connection has gone completely, pulling the fuse doesn't stop the speedo does it? With the rear wire connection I fixed I could disconnect the wheel end and a little connection box under the car and test continuity, the front wheel wire goes up into the engine compartment then into the loom, so not sure how to test that.
