Diode for Installation of Brake Controller on 2018 Toyota Highlander


I have a 2018 Toyota Highlander. RV Dealer installed a TEKONSHA # 90160 Brake Controller. I see this problem seemed to be solved on Tekonsha #90195 using your diode assembly. Is this the same problem on 90160, seems likely that it is ? On my system I get the error message at all times when I connect the trailer cable. Appreciate your answer. Thanks

Yes, you will likely see the issue of the malfunctioning Pre-Collision System (PCS) on your 2018 Toyota Highlander with the Tekonsha Primus IQ Trailer Brake Controller # TK90160. So you can do is the Roadmaster Single Park Light Diode # RM-690, or you can use the Pigtail Wiring Harness with Diode for Tekonsha and Draw-Tite Brake Controllers # 7865.
