Does anyone have a full list of fault codes for the Teckonsha Prodigy brake controller?

Yesterday ours started showing an intermittent fault code "oL" that comes on while braking. The number display and then oL then back to numbers and when braking completed it goes back to "c" again.

While checking everything last night I found a wire broken close to the rear right brake drum and then also found that the wire was broken where it is clamped as it enters the rear of the brake drum. This meant that the brake drum had to come off and run a new wire out and joining inside the drum then to the controller wires.

Everything appears to be working properly now but the fault code "oL" appears sometimes.

Hi Brian,

We have the manual in PDF if that helps at all. Please send us your email address and we will send it to you.

In the meantime the manual states
o.L - Prodigy 'sees' an overload condition during operation
Also notes that the 0.L flashes 2 times per second.

That is all that is said.

Cheers

Allan and Sharon

Thanks Allan,

I have sent you a member message with email address.

The only thing that we could think of was overload but then how do you overload the system unless it is one wheel is adjusted too much and causing a problem.

Hopefully they put some explanations next to the meaning of the codes.

Any other brake controller we wouldn't know that there was a problem.

Brian,
o.L flashing 2 times a second means the Prodigy "sees" an overload condition during operation.

other fault codes are:-
o.9 flash 2 times a second, "trailer is connected & Prodigy loses connection to battery ground.

S.H flash 2 x a second = 1. brake wire sees a short circuit during idle condition.
2.use of some test lights or non Tenonsha testers can cause this problem.

-.- the 2 lower bars flash = Prodigy is mounted at too low an angle.

-.- (cannot type it as indicated, but with the two bars at top of display) = Prodigy mounted too high.

n.c. flash for 15 seconds = 1 trailer not connected to tow vehicle. 2 Trailer connected with open circuit on brake line. 3 Trailer connector disconnected or corroded. 4 loss of trailer brake ground.

"blank display" no display with pedal or manual activation = 1 loss of power to prodigy 2 loss of ground to prodigy.
"blank display" until activation = Prodigy is in power saving mode due to no motion for 15 minutes.

0.0 no braking = power control set to 0

P.L Power interruption while brake pedal is depressed.

Hope this assists.
Cheers
Ian

Thanks Ian,

Any ideas of what could be the cause of an OVERLOAD. We have just had a whole suspension arm and brake assembly fitted in Birdsville so it could be something with that.

Brian

We needed a manual and just contacted Tekonsha via email from their website

( www.tekonsha.com). Had the maunal within 24 hours and they were very helpful - encouraged us to email back if we could not understand anything in the manual.

Hi Brian,
I had a problem today - I had not towed the van since Easter and there was not a problem then. The Progigy was flashing SH (a short) while driving and oL when I put my foot on the brake.

Turned out to be a short in wires on the plug lead. Obviously an old problem that shorted today. Wires taped up and all worked fine again.

Thanks Noel,

I got this reply from Tekonsha with the PDF attached. Looks like I have to do some more searching. After getting lots of stone hits it is not an easy task.

Brian,

Thank you for contacting Technical Support. In response to your email, the OL code is present mainly because there is a problem somewhere along the electric brake wire. I would inspect the trailer wiring looking for broken wires, or spots where wires could have wore through as well as inspecting brake magnets for possible failure. I have attached to the email a technical bulletin for testing brake circuit resistance to help you verify your wiring issue. If this only happens as you are driving or as the numbers are higher you can disconnect one wheel at a time to see if you have a magnet that has a short in it after voltage is generated through it. I have attached the instruction manual for this control unit as well which outlines the trouble codes you may experience. If you have any questions or need further assistance feel free to write back or contact us at (888) 785-5832.

At last I have found the problem causing the fault codes.

Last time I had a fault I started with the wheels and eventually found it in the connector plug.

This time after checking the wheel wires were in tacrt I started at the plugs on both car and van, and eventually after jacking the wheels and removing the hubs found that one in one wheel the magnet had come off the support and the wires that broke off were causing the short and Overload faults.

Van stops much better now with that wheel isolated.
