TD5 Fault Code Advice. (3,5) DRIVER DEMAND PROBLEM 1
Evening all. I think my Defender may have a problem... Just the one... Rolling Eyes

Anyway the fault code list goes like this;

NANOCOM - TD5ENG.APP - TD5 ENGINE fault file

(3,5) DRIVER DEMAND PROBLEM 1, (LOGGED HIGH).
---
(10,4) GEARBOX / ABS DRIVE OPEN LOAD, (LOGGED).
---
(14,4) GEARBOX / ABS DRIVE OPEN LOAD, (CURRENT).
---
(20,2) TURBOCHARGER OVERBOOSTING, (LOGGED).
---
(14,6) MIL LAMP DRIVE OPEN LOAD, (CURRENT).
---
(14,7) GLOWPLUG LAMP DRIVE OPEN LOAD, (CURRENT).
---
(10,3) TACHOMETER DRIVE OPEN LOAD, (CURRENT).
---

The last three I caused by testing the systems. The Over-boost is due to recently getting a remap and not having a boost box.

The two gearbox ones are odd and I do not have ABS on the 110.

It is the first one that I need advice on. Driver demand has got to be the accelerator pedal, right?! How do I go about testing the pedal?

Will TDCI pedals work on a TD5 as they are much cheaper. Look similar too from what I can see.

Yes I am fairly sure it's the pedal a friend had the same however from memory he changed the pedal and no change but can't remember what solved it.

Okay you could try clearing them (again) and then disconnect the battery and hold the pos and neg together (neither connected to the battery) for about a minute. Reconnect and try reading codes again. If the codes remain time for some further digging or a better diagnostic like a Nanocom or testbook. 2010 Range Rover MkIII Autobiography Super Charged (Idris)

Its not unheard of for them to fail although its quite unusual.

I had one fail on mine when it was a TD5 and still under warranty. They replaced it straight away and after that I always carried a spare new one just in case. 2001 90 HT 6.0LS/6spdAuto.

There are two types of pedals for TD5 - older with 2 ways and newer with 3 ways. Way means variable resistance sensor - so there are more than one in the pedal - for safety reason. Details are in RAVE.
With Nanocom you can change this setting - it is in the same place, like injectors settings.
I have experience, that with 2 way pedal and ECU switched to 3 way, I get similar fault in ECU and car will only idle. "Drobek" = The Small One - Discovery 2, "Blufínek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo Smile

Thanks for the tip, will give that a go. I actually have a Nanocom (quite frankly the best christmas present ever...) and that is where the fault codes came from. It has also highlighted that after nearly 170k miles the injectors are a little erratic, or at least the cylinder balance values are. But that is the topic for another thread I thnk.

So I see from a google search last night. Also from those searches it appears the more frequent cause of this error appears to be chaffing of the wiring loom.

Ok, so being a 2003 TD5 I am likely to have a 3 track pedal. So I need to test the resistance of the tracks. I notice on the nanocom feed that track 1 shows a reverse voltage, is this normal?

Look into the RAVE - there is detailed description of the pedal resistance. And yes, it is OK, 2 main ways works in opposite - safety reason for possible short in wires. ECU is sensing both ways and comparing them. In case of a short, the car will not increase the speed by it self. Third way is for better precision of control. "Drobek" = The Small One - Discovery 2, "Blufínek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo Smile

Yup, don't have RAVE... But thanks for the response. All good with the voltages then...

On the TD5 with a three track throttle position pot it is normal for one track to be reversed. The idea is that the sum of the reverse track and one non-reverse track should be a constant voltage, this is monitored in the ECU for fault detection purposes.

Super. So that must be where the "accelerator Supply (V)" data comes from then. In which case that data should show (providing all is A-OK) an almost constant 5(ish) volts... right?

I would check the wiring or just rewire the pedal to the ECU as the wiring can also give problems!

As above. Wiring issue between the ECU and pedal

As a temporary repair, it can be programmed to a 2 track pedal Thumbs Up
