My 2002 Td5 won't accept the 10 pulses to disable the ABS and TC either. It has a Wabco system.

Pull the fuse. Wire in a fuse socket and a switch. Mount the switch on the fuse box lid. Now you can turn it on/off when you want.

Just for info, tried the 10 presses method, turns mine off, till speed increases above 5mph, then lights turn off, so assume that indicates that TC is reactivated.

Wow, only left this a day and we have two pages of replies.
The switch is the obvious choice, personally I think I'll have it dash mounted. Also interesting to hear of the effect ABS/ETC can have when steep hill descent goes wrong. many thanks guys. John. 2.2 90 XS 88" Series One Old Norton

The TC will reactivate because the ABS has been triggered as the speed has reached the default speed.

I was taught to only hit the brake pedal, stall engine, apply handbrake, press brake pedal, select reverse gear, release clutch fully, handbrake off, both feet off all pedals and then crank starter to start engine in reverse gear, and reverse down under power/engine braking |

TC is there for a reason, rather learn to use it properly.

Good point, that is the safest way to to cope in the situation of a failed hill start, but it's allways hard to do the right thing when you're in the front line. One thing for sure though is that the "right way" wouldn't have worked anyway, the brakes were being overidden by the traction control and the pedal was solid so no matter how much standing on the pedal was going to make an impression. What would happen when the tc eventually stalled the motor I don't know. perhaps the brakes would hold, I'm not a great fan of pulling the handbrake on when moving and trying to guage that moment between engine drive and when gravity takes over, it can be very quick!
It is one of those situations where you do what seems right at the time, I would like to try the situation again under much more controlled circumstances and definately not have such a long run back as when it happened to me, trouble is I haven't found the situation again the motor keeps getting over what I put at it! |

The disturbing thing about this thread is that it suggests that the driver has no ability to brake when TC is operating. Whilst clearly this should never be a problem (since the TC should instantly turn off when the right foot moves from the accelerator to the brake) the driver experiences in this thread suggest that that doesn't always happen. It also suggests that there may be failure modes in which the TC could lock the driver completely out of the braking system. I don't have TC on my Defender (and don't want it, nor ABS) but my Disco2 has both. I can't say that I have ever experienced any of these problems with the Disco, but if/when I get the chance I'll see if the system can be provoked into doing this. |

Yes - i don't doubt the real world experience of those that have had this happen to them and slightly alarming to think of the consequences.
I'll try and remember to try this out for myself when I use my next experience voucher. |

Having experienced the locking out if you continue to keep pressure on the brake pedal it will after a second or two lose the built up pressure and allow you to use braking again and to then select reverse in a controlled manner.
Touching the clutch is the worst thing to do and the traction control when used properly is a great tool and addition. When there is no wheel spin from acceleration the TC is no longer needed and can then allow the brakes to function again. This is by far the best way. It is difficult getting used to having technology on a Defender but when used properly it really can help rather than hinder Anyway thats my 2p's worth  |

When I experienced the problem it was with my Td5, the ascent was probably as steep as you would want to be in any motor and was a very long drag. It was after a dry spell and the surface was loose hence the loss of traction, the tc had kicked in way before reaching the point of failure and it had been working hard. I do remember reading, whether in the handbook or elsewhere, that tc should be used for short periods only, 30 seconds springs to mind. There were so many factors involved that I am of the feeling that it couldn't quite cope with the conditions of the time. I have tried to replicate the conditions but in a much safer environment at other organised pay and play sites and have only once experienced a hard brake pedal which soon became normal when the clutch was pressed. This problem only seems to happen when tc has been working very vigourously and it may be due to other factors such as the brake fluid heating up, so much over input from the wheel sensors etc etc.
All that I wish to say is just be aware that even though tc is quite a good gadget, it does have its limitations. [/list] |
