How To Fix ABS Error On 2016 Toyota 4Runner with Tekonsha Trailer Brake Controller

Question:

I have a 2016 Toyota 4Runner using a Tekonsha 90160 Primus IQ Brake Controller and get the ABS Error. I see two different threads on this this and with two different answers and wonder which would work best for me. One references using a Pulse Preventer 5501 and the other a wiring harness 7865 which is not confirmed for my year vehicle. Could I just use the 3041-P and be set?

The solution to fixing the ABS Error on a 2016 Toyota 4Runner with trailer brake controller like the Tekonsha Primus IQ Trailer Brake Controller part # TK90160 is to combine the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers part # 3041-P and Pigtail Wiring Harness with Diode part # 7865. Just cut the brake controller end off the first harness and splice on the one from the second. You need a diode on the red wire to stop back feeding which is what is causing the error message and this harness has that. This will work for any Tekonsha brake controller on a 4Runner. You'll also need four butt connectors part # DW05714. I also recommend creating a ground of your own like on the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers part # 3041-P.

Please note, not all 4Runners have this issue so some get away with just the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers part # 3041-P.
