finnarne Posted September 7, 2018 Share Posted September 7, 2018 My co-driver has just rebuilt his 6x6, and replaced the old V8 with a TD5. (yes it' sbeen argued that he should have kept the V8, but he wanted a TD5...) The engine, wireloom and the ECU comes of a MY2003 Defender, which also had ABS/TC. As said, this was a MY86 V8, with drum break in the rear, and a reinforced front axle. And there would have been som complications replacing the second axle with a newer one. And there would of course have been some issues getting ABS working on 3 axles. The engine swap has gone well, it drives and brakes nicely. But there is an issue with the ABS warning light in the dash. We've tried to disconnect the WABCO-unit, which I believe is the ABS control unit, and that did not work. Also the brake warning light is on all the time, although there should not be any issue with the braking (except the missing ABS sensors, and input to the WABCO-unit). Does anyone have a suggestion ?

ianmayco68 Posted September 7, 2018 Share Posted September 7, 2018 There’s a work around used when you fit td5 gauges and warning panel to an older defender to turn the warning light off don’t know if that would work . Look in the wobbly wobbly speedo thread in the technical section. Quote Link to comment Share on other sites More sharing options...
Ex Member Posted September 7, 2018 Share Posted September 7, 2018 (edited) Remove the bulb for the ABS light and rewire the brake warning light directly as per an 86.... Edited September 7, 2018 by Red90 Quote Link to comment Share on other sites More sharing options...
western Posted September 7, 2018 Share Posted September 7, 2018 can't remove the bulb if it has a td5 warning light panel as its all led. the ABS led wires are [td5] red/slate grey trace wires. on the 16 way plug of warning light panel - try joining 16-10 to 16-6 that should put the ABS light off. the TC [traction control] light is on the same colour code wires as well.

Scotts90 Posted September 7, 2018 Share Posted September 7, 2018 Non ABS/TC td5s had the wiring bridged out as part of the loom, that's what mine has. 1 Quote Link to comment Share on other sites More sharing options...
finnarne Posted September 10, 2018 Author Share Posted September 10, 2018 That seemed to do the trick. Shorting out those 2 pairs of pins on the 16 pin connector to the instrument panel worked (I was told). 2 Quote Link to comment Share on other sites More sharing options...
