I had found that page you posted last night, and after some real head scratching and then I started to realise the only thing I had done different to the standard Jimny was fit LED bulbs. I had done this because the rear tail lights are sealed behind a perspex cover and very tricky to access. The idea being LED's have a less likely chance of failing etc! Little did I know it was going to cause weeks of sleepless nights!

A little googling late last night, found several posts about LED lights and ABS's warning lights on Asian cars. It seems that's the ECU carries out a check on the brake light circuit to ensure its working and looks for a slight load from the traditional incandescent bulbs but with LED's its cant pick up any resistance/load and goes into a fault mood switching the ABS light on!!!

Fitted a 50w resistor on the brake light circuit and ABS warning light now switches off!

With out my mates professional code reader, I would never have looked at the LED's and brake light circuit.

Sounds like you have come across this problem before?

Not come across it before but read the description in that manual extract and realised that whilst it's talking about "voltage on a pin" that it's actually measuring resistance and LEDs give resistance issues
