ABS and Tyre Pressure Lights
This might be an old subject for many of you, but as I've only had the car a week, it's all relatively new to me - more used to my old and my son's current Austin/Rover Mini's.
When I got the car, the above mentioned lights were on. This didn't really phase me as I have plans to buy an ABS/Airbag/EML diagnosis device. I've currently got an EML one from Machine Mart (Clarke branded) and it showed no stored or pending fault codes.
Have inflated tyres to 30 all round (fronts were 21 and 25psi and rears 15 and 19psi) and reset system via button under handbrake lever.
Now I have noticed that when I start the car, both lights are on. After about 3 seconds the tyre pressure light goes off. I drive away and after about 5-10 meters, the ABS light goes off as well. My road is about 100 meters long where I turn right and then another 40 meters where I hit a T-junction and slow to stop. I nearly always turn right due to horrible speed bumps if I go left.
When I slow down there is a brief 'hissing' noise which seems to come from the rear. I generally start to turn the steering wheel to the right as I approach the junction itself and then the ABS light illuminates closely followed by the tyre pressure light. They will stay on until I get to my destination and switch off the engine.
When I get back in, the same happens when the lights go out, but usually they don't come back on again, although I hit a pot hole and that made them come on again once.
My thoughts are poor connection on abs sensors to wiring loom, possible rear wheel bearing affecting sensor's ability to read the rotation of the wheel, lowering springs on rear, fitted by one of car's previous owners, making the rear wheels lean inwards and wearing inside edges of tyres.
Also have noticed steering wheel is about 10-15 degrees out to the left when driving in a straight line. Maybe not helping and I mean to get it looked at when funds allow.
