How many KM have I got once I get "CHECK BRAKE PADS" warning

I think, from my ailing memory, that the ABS computer doesn't go through all (or at least finish) it's routines until the car is travelling faster than 40kph. It might be less than that but faster than a crawl anyway. I know these ECUs supply data to each other for error reporting so maybe that's where it all ties in. You know, driving normally, pull up at stop sign/intersection. Computers see brake activation and speed change and now there's a circuit on the pad sensor.

Which possibly explains why the short test drive is usually what makes the message go away typically.

Sounds to me like you coerced the ECUs into checking the status of the sensor at some point.

I Know Faultmates can read the status of the brake pad sensor in live data going to the instrument pack. I think probably it would show up on a Hawkeye as well. Don't know enough about the IIDTool but I'd suspect that it can probably see the data as well. I guess it's a matter of familiarity and knowing where to look.

Anyway, glad it's all working well (without the sound and light show) now.

Cheers,
Iain

However, my Check Brake Pads warning is still coming on the console when I start or stop the car (boings a lot - which is annoying), and the red "Brake" light is still on.

I've tried resetting with my IIDTool diagnostic box (cleared all faults) but it's still warning me.

BTW - I replaced the sensor (which had worn through) when I replaced the pads.

What have I missed?

This confirms that there is no ECU setting that needs to be reset for the brake pad wear sensor. Just replace and drive away! The truck will look after the rest.

I've already posted this on a related thread, but thought it might be useful for anyone reading this thread too.

If is an excerpt from the LR manual on how the message and light on the dash operates.

Brake Pad Wear
The front brake pads are fitted with a wear indicator system. The Front and Rear pads are wired in series to the
instrument pack which continuously monitors the circuit. When one or both pads wear to their allowed limit, the
indicator circuit is broken and detected by the instrument pack software.
The instrument pack illuminates the general brake warning lamp in a red colour. The instrument pack
simultaneously, transmits a message to the LCM which displays 'CHECK BRAKE PADS' in the message centre.
When the brake pads are replaced, the instrument pack withdraws the message and the warning lamp
illumination when the ignition is in position II, the engine is not running and the vehicle is not moving for 30
seconds.

Don't know which LR manual and for which model but my 2005 L322 RR td6 does not display anything on the instrument panel when the pad wear warning lamp is lit.

Also only the lhs pads are fitted with the wear sensors.

I agree that it is an automatic reset after a damaged sensor is replaced.

Was sent to me by Gap-Diagnostic in Canada, as I was trying to use their IIDTool to reset the warning (which of course was not going to get me very far - but I didn't know at the time....)

OK understood - I operate HawkEye diagnostics which are comrehensive and are not VIN or even model limited. My HawkEye is capable of diagnosing and model or variant L322 from 2002 to 2012. I also have RR classic and D2 enabled.

I used to run (and distribute) blackbox products but their customer service was hopeless to say the least. Blackbox have a world wide poor reputation in many respects. I still have some of their products and have not bothered to enable gear that I paid for as it is just not worth the hassle. They use customers as guinea pigs with beta versions of both software and hardware.

I did some research recently on IID tool and was surprised at how undeveloped that product was - it seemed that every function is under development and to be released in the future. I also suspect that north american LRs are built to a slightly different specs that Aus which follow UK specs closely. That was observed when the IID had nothing for tdv8 diagnosis. HawkEye has had that capability for years.

What your LR manual advice maybe based on is the 2006-2009 L322 or as they refer in north america as the "Jag engined" L322.

I was (am) on the IID Tool Beta Testers program, so I wasn't expecting it to be 100% up front, but it got me through my dramas with replacing my front air struts, and it did that very nicely. All the EAS functions seem to work, which was what I needed.

For the home-repairer, it is a good solution. If you are a full time mechanic or a workshop then there will be better tools, but for $300-odd it was a good option for me.

BTW - Thanks for all your input on this - much appreciated.

Also - they have a good system of updating the software. Just plug in with a USB cable to your PC and it re-flashes in about 2 or 3 minutes. Very easy.

It's always interesting to learn from other's experiences.

$300 sounds Ok but that is VIN locked isn't it?

As I run 2 x RRC, a D2 and 2 x L322 my HawkEye has worked out cheaper per truck.

I currently attempting to make contact with the producer of HawkEye as it is due for a full software upgrade with a module to allow re-programming functions.

It seems that the quoted information is relevant to all L322 models (UK, NA and ROW) from 2002-2009 at least.

It is a direct quote from the System Description and Operation section of the workshop manual. It is in there for the early versions (02-05) and then the face lift (06-09) but I don't know for the 2010+ models because I don't have that information.

So, definitely not based on the NA spec beasts only.

It's all in RAVE somewhere but there is a lot of information to wade through to find it. I only found it because it was near some other info I was tracking down.

Cheers,
Iain

You can have 3 or 4 VINs on the one unit, and it is not much for extra VINs. I've only got 1 L322 so the VIN lock wasn't an issue.

Pity I also need a NanoCom for my TD5 as well :(
