As far as i recall the main problem with it was it listed lots of fault codes but did not explain what they meant.
It was very clear actually, so must have had an update. It threw a rear right ABS sensor fault. Changed the sensor out and the fault cleared. So it doesn't get mixed up with the sides like some others seem to. No fault codes on Traction or on ABS but still have the lights. New thread time methinks.

then there should be a fault present. Also check the brake light switch.
That's going to be my next port of call. No faults present anymore as the tool found and cleared the faults. Would the brake light switch throw a fault? I'm going to maybe bleed the brakes tomorrow as per RAVE. There might be air in the system throwing a fault maybe?

The brake switch needs to be set correctly as it switches two ways, you have to push the peddle down pull out the plunger then let the peddle up and it will set, that is as long as the switch its self is not faulty. and yes the switch will bring up abs light mine did.
I will be checking that tomorrow and will update. I can only assume that a fault code would be thrown if this was the issue though? Hopefully not! I know I have 2 very very very very seized front calipers (slider pins are slidey and pinney, so no issues there) and so I will check the brake switch when trying to blled the system and change out those calipers.
Update lads. All ABS sensors changed out. Brake pedal switch checked and boojied. Two new front calipers. A RAVE bleed. An ABS top up. STILL historic ABS fault code. There is a caution to this tale though. The BECM was holding on to an ABS fault and so every time I cleared the code from the ABS ECU, it was just showing up again from the BECM. I cleared both at the same time and the fault disappeared! No lights on the dash!
Now on to the drivers door handle..... I'm picking one up from the breakers tonight that hopefully has that triangle clip still attached, so the handle pulls on the actuator rod. I'll let you all know. She should be in for her MOT by Thursday!

The BECM does not store fault codes only thing you can clear from BECM is outstation memories and RF memories.

Interesting, I wonder what he found and thought he cleared in the BECM?

He thinks he has but cannot see what it could be that effects ABS. You either have WABCO C or D. Faults can be read and cleared from those but the BECM holds no fault codes. Other than the data previously mentioned. He is using an Hawkeye though so it may be down to some anomaly in that.

Hawkeye does seem to be less than useful on the P38.

Well whatever it thinks it's doing it cannot be doing. I don't know how the Hawkeye works never used one. But from reports on here over time it is nothing like as good as Nanocom that's for sure. I recall people posting lots of numerical fault codes asking what they meant, as far as i am aware at that time there was no list of or explanation of the fault codes it produced. Maybe it has had an update.

Nanocom was not an option when I bought my Faultmate, but I'm more than happy, it's unlocked for all modules on post EGR P38's.
I can't say if it's an anomaly in the Hawkeye or not but I cleared the exact same 'historic' fault code in the ABS ECU many times and each time, the ABS and TC light stayed on. I gave up for a spell and started looking in to what the Hawkeye is able to read and the only fault code the BECM had stored was an ABS fault. I then cleared that but not the ABS ECU and the lights stayed on. So I cleared both the ABS ECU faults and BECM 'ABS fault' before starting the car again. All lights went off as they should after that. I can't fault the Hawkeye really. Any code it's shown me has a full explanation to it and not just a number.

As Wammers said, the BECM does not store any fault codes, so whatever Hawkeye is doing, it cannot either be reading or clearing fault codes in the BECM.
