Hi all,
Some time ago, I installed a redarc towpro into my car. Unfortunately, I haven't had the opportunity to hook the caravan up until recently so did not calibrate the unit.
Today I did hook it up and for some reason the unit will not calibrate. It just keeps flashing blue and green. It also seems it is sending 12v to the caravan, as it immediately locks the brakes when the car brakes are touched. I assume this is because it is yet to be calibrated. I switched the unit to manual mode, but even on 0 setting it was still locking the brakes. I am not sure if I am doing something wrong or if I was unlucky and got a dud unit. I will be ringing Redarc in the morning, but any ideas beforehand would be appreciated.
Scott

I have just sent Redarc an email (I believe they are off until the 12th, phone went to a message bank), so will wait on a reply. Thanks for your suggestions and I will let you know of the outcome.

It does sound a bit odd. I installed ours recently (Tvan/electric brakes) & whilst calibrating within moments of the wheel lock up the flashing light changed to a ‘solid’ light as per the manual. You didn’t touch the brake pedal during the process before the calibration had had a chance to complete did you? If practical, if I were you, I’d try a reset, & have another go at the calibration.

Being an automatic, I have have to touch the brake to get it into drive, I guess I could try putting the car into gear with the handbrake on then put the trailer plug in, anything is worth a go.
The rest doesn't seem to do anything, as it is still flashing blue and green saying it is out of calibration. I also tried to disconnect the power to the unit but made little difference.

I suspect that is your ‘problem’.

Try:
Drive to long straight quiet road in manual mode, trailer connected.

Stop, in drive, handbrake on.

Set Tow Pro into calibration mode (flashing lights) as per manual.

Take handbrake off & drive off.

Do not touch brakes again until flashing light becomes ‘solid’.

If that doesn’t work I think you have a problem.

Going by reports here and there Scott, you can expect to be well looked after by Redarc (another good South Aussie Company :-)....never heard a negative word about their Tech follow up....quite the opposite.....I queried the tech aspects of one of their products at their front counter a few years ago... the engineer that designed it came out for a chat !
