Check the antilock wire beneath the master cylinder.
Also the RWAL (rear wheel anti-lock) computer will store a (1 code at a time) code due to a faulty system. This code can be read by counting the flashes starting with the long flash as one and following with the short flashes there after (1(long)2(short)3(short)...and so on). The long flash always starts the new set of flashes. If the brake light stays on then a code reader will need to be used ($20 on ebay), which is read the same way.
Look under the rear of the truck on the left side frame rail. The wire for the back up lights is light green. The brake/turn signal wire on the left side is yellow. The brake/turn signal wire on the right side is dark green. Your taillights and bumper lights are a brown colored wire. You also have a black ground wire. I ; those are the wire colors for the rear lamps on my truck anyways. I own a similar Chevy truck. Good luck. I ran into one that may shed some light. The brake light switch harness get damaged from the poor position it is in. It is a real mother to get at too. Post your results. I had the same thing on my '91.It was a headlight switch

As far as i know the only brake warning light is for the Parking brake. In my truck sometimes after i pull the brake release lever (lower left dash, next to the hood release) the light remains on... so you can try pulling it again...or pull it and pull the brake pedal back with your foot. If that dosent fix it im not too sure what else to tell ya...

Well, hello there, friend. A BC warning light on an Iveco Eurocargo is usually related to the vehicle's brake system. It's a gentle reminder from your truck that there may be an issue with the brakes that needs attention. Just take a deep breath, check your brake system, and if needed, seek the help of a professional to ensure your truck is safe and happy on the road.
