Solid blue LED turns off instead of blinking when push-to-start button pressed twice on 2008 Highlander Hybrid

Question

I connected everything last night. I began the programming sequence but when I push the push-to-start button twice, my solid blue LED turns off instead of blinking. When I unplug the "A" harness from the unit, my blud LED comes back on. I did not connect the hood pin, valet switch or parking light out but made the other 7 connections. I would like to connect the parking light but wasn't immediately able to locate the proper harness to tap on to.

I did notice that the colour identified in the manual of "blue" for the C3 connection should actually be black on the highlander as 1. there is no blue wire on the OBD-II connector for my vehicle and 2. the #6 pin is black...

Hi Sean,

I did notice that the colour identified in the manual of "blue" for the C3 connection should actually be black on the highlander as 1. there is no blue wire on the OBD-II connector for my vehicle and 2. the #6 pin is black..

Yes, the CAN-Hi on the Hybrid may be Black and not Blue. The important thing here is the pin-out. Can-Hi and Can-Lo will always be Pins 6 and 14.

I connected everything last night. I began the programming sequence but when I push the push-to-start button twice, my solid blue LED turns off instead of blinking.

This has to do with the Can connections. The EVO would act like this if either the wires are reversed or a faulty connection.

Just fixed the problem. Because the wire was black instead of blue, I must have looked away between making this realization and making the connection. It turns out there are 2 black wires on my OBD harness and I simply used the wrong one. Quick fix and everything got programmed fine. Now into another ``issue``.
