after doing a scan said the ABS module is bad and to replace it will cost about N115k, though he said I should still be using the car. readings I have done online suggest that I shouldn't take the warnings lightly.

Generally emission-related issues, like bad O2 sensors, air fuel ratio sensors, EGR and MAF will not only trigger a CEL, they will also disable ABS, Traction Control and VSR (if fitted). So ABS and VSC warning lights will be illuminated, in addition to the regular CEL. A fuel injector out of spec in D4-D models will also trigger the same warnings.

I am willing to bet your "mechanic" is either lying to you, or wrongly assumes you have an ABS fault. Replacing your ABS module will NOT resolve your issues. Since you had your car scanned, I would post the results here. You'll be surprised how much less you have to spend to get things straightened out.

In the meantime, ditch that sap of a mechanic of yours, he's an idíot.

siena u have done very well. I love the words of encouragement. I have also learnt from ur post. Does it mean abs module rarely fails? What does one expect with a failed abs.

GAZZUZZ:
sorry bro, you just got bleeped, always get a pro to look over a vehicle before paying. The abs is a known issue with corrola 2007-12 abs unit will set you back by 450k (brand new unit) I [b]will personally prefer converting the a.c to the clutch type [/b][b][/b], it's more tolerant to abuse and rearly fails.

Inception:



i think say you go preach against this bawse



Any way that would still be my logical choice too. the compressor ( also found in the 2AZ-FE engine variants of the 2007-11 Camry) does not come with a magnetic clutch, but rather a solenoid which regulates refrigerant flow at the suction end of the compressor, therefore practically reducing 'engagement shocks' that a conventional (magnetic clutch) one would do and in effect reduce load on the engine which in turn should improve drivability and fuel economy.

The problem with this kind of compressor is that it works continuously, (whether the ac is on or not) and once there is a leakage of refrigerant ,
it will surely fail. Also to note is the solenoid in which when it goes bad , na the same story of kaput be that.


Replacing the bad one with a conventional one would be ok, as a relay would be incorporated to switch on and switch off the compressor in response to the duty cycle. But i would advise that the cooling fan system be left as it is(i.e factory setting), and the thermostat be replaced if it has been removed already.

GAZZUZZ:


I learned the hard way, after 2 compressors 1 condenser I went all kazeemy on the car. Sometimes you incur loss to save face.

Siena:


With a failed ABS module, the brakes will revert to conventional brakes, and the ABS (and VSC / TCS if fitted) warning lamps will be illuminated. An ABS fault however will NOT trigger a CEL
