on my 57 plate 2.4 - switch off - switch on, start engine, immediately press the brake pedal 10 times and then the ABS & TC lights stay on - both systems are disabled until you switch off and re-start. not sure if this works on the 2.2, worth a try. Series IIa Lightweight - Long Gone

Hi Skyeplumb, just tried that, it didn't work, at least no lights stayed on.
I have since done a search on here and it seems you can remove a fuse or put a fused switch across the fuse to switch off ETC and ABS. However, I see there are two fuses for this, a 30 Amp on F8 in the main fuse box and a 10Amp on F6 in the Secondary Fuse box. I presume we connect the fused switch in place of the 30Amp one in the Main Fuse Box but if anyone knows any different please advise. Cheers all. John. 2.2 90 XS 88" Series One Old Norton

Don't think it's your traction control that's the problem. Revs still increase in mine even when I completely stuck, in fact you need to get a wheel or two to spin to make it work.
I might be wrong but think something else is upsetting yours. But pulling the fuse out would prove that I guess. |

Remind me of that, that you can still get your revs up, when you allmost get to the top of a loose surface ascent. I know mine's a Td5 but when gravity and the TC braking wheels trying to find grip, you won't have a lot of engine revs left. That is when you will find the brake pedal is solid and isn't prepared to accept any driver input. In my case I was back the way I came because as soon as I dipped the clutch gravity took over making me a passenger. When we had come to a halt at the bottom did everything go back to normal and I regained control of the brake pedal.

It's the 10A fuse
The 30A is always live (=power) to the modulator, the 10A is the "enable" signal from the ignition switch to the modulator  |

CFB, it's not only on failed hill climbs. seen dangerous things because of this and it's certainly something to keep in mind
Had it today again, we are clearing roads on long steep hills, so we need to stop on the slopes to cut down the trees the mulcher coming behind us won't eat. Each and every time TC is working at the moment you brake to stop... nothing and gaining speed fast going backwards. TC switched off, no problem. So the switch comes in handy. |

Fair point, guess it's to do with pressure in the ABS system caused by the TC? Andy

So are we saying that the only way to turn off the TC (td5 & Tdci) is by fitting a switch/pulling the fuse?
Or is it only the 2.2 Tdci that does not allow the 10 pedal presses? Andy |

I'd always thought a switch was the only option, never heard of the ten pedal presses before. Wonder if that just causes an error in the system??? Andy

I may need to fit me one of these switches. Havent tried the ten pedal press trick ill try it one day if inremember to. But a switch would be much simpler

i believe that the change in systems was with the intro of the Bosch TC system over the Siemens system (10MY) Jul 10, early system can be turned off with the 10 pedal pushes within 10s of ignition on, later system cant unless fuse is pulled. consider the implications of ABS off and an incident too if you did pull the fuse.

"Tut tut, braking on a failed hill climb. Reverse gear and let the engine do the work"
As has been pointed out that when the TC is in operation, the ABS is working overtime and the brake pressure is right up. As soon as you dip the clutch to go from a forward gear to reverse you would like to hope that you can press the brake pedal to hold you on the slope and then descend under control. In the situation when you get the failed hil climb, you hit the brake and clutch pedal at the same time, that split second it takes to get the gearlever out of the forward gear and into neutral, the brain registers that the brake pedal is solid and reverse is occouring making it impossible to get the reverse gear engaged. Another reason for making sure that you are ready for the unexpected, never block someones "escape route" and especially when on steep slopes don't crowd round the bottom and make sure it's clear before your go. |

JST, i'm not clear on this but is it possible there was a change on the TD5's system from ??? to wabco, which is present on 2007 till ???? 2.4's, later ones have a Bosch system if i am correct. (which also does not accept the 10 pulses.
I know of late td5's that do not accept the 10 pulses (and early TD5's that do) and i know my 2007 build 2.4 does not also. It has a Wabco system. |
