ABS issues
DAIHATSU SIRION (M3_)

 have a Daihatsu Sirion 11 M300 1.3 petrol automatic,
registered in 2008, the ABS warning light and the handbrake warning light on
the dashboard will not go out. So far I have had the car to the mechanic who
looks after it and a local, well established auto electrician, near to where I
live, they could not diagnose the fault because they did not have the correct
diagnostic tool, I then took it to a Daihatsu dealer who told me that, after
reading the error codes, it needed a new ABS pump, which I duly bought (880 GP
pounds) they fitted the pump and they told me that 2 error codes had
disappeared but the error codes for the rear wheels were still there, codes
CO215 CO210 are still showing. I have bought from Autodoc two rear axle
bearings with sensor as per the website relevant search, these have now been
fitted and the fault is still there, my mechanic and the auto electrician are
at a loss, as am I, there is continuity from all the wirings from wheels to ABS
ECU, we have a reading from both front wheel of 1.10 and a lesser reading of 0.895
from both rear wheel, when rotated, there has been a ”blink” test performed and
the car was run at the required speed and the lights are still on. Can anybody
help me resolve this problem, incidentally the interior courtesy lights have
stopped working as well at the same time, and all fuses have been checked.

Below is part of the report from the Daihastu dealer and
their suggestions,

New ABS pump fitted. After setting new ABS pump to normal
operating mode and clearing codes again,

C0215 and C0210 error codes come back on. Possibility of
readings not high enough for normal operation.

Suspect needs new ABS wires fitted to eliminate possible
wire fault, NOT FITTED, if no better

need rear hub and bearings fitting.   NOW FITTED
