Hello Scotty,
First I would like to start with a thank you for blessing us with years of great automotive content. As a former tech you bring a lot of real life information and emotions to the automotive industry. I feel like the automotive community can really relate with you and your Videos.
I purchased an 2008 Toyota Avalon limited with 195k miles from my neighbor for my son as his 1st car. along with TLC it needed an evaporator which i just changed out before summer hit. After reassembly of the dash and other components the car has given me a no start/ no crank which I believe is from the immobilizer.
-has a smart key (fob) with push start
-car seems to be in on position as soon as the battery is connected and brake lights on
-( brake pedal switch physically working)
-car functions not responding to fob commands (fob red light does blink when buttons pushed)
-car acknowledges fob not in vehicle when closes door
-push start not responsive
-no OBD codes
-security reset using OBDII plug 4 and 13 with paperclip did not work
My fear is that I would have to tow the car to the Toyota dealer to reset all
What are my next steps? is there things that i can do before giving in and taking it to the dealer ?
Thank you,
Hansel
Well it obviously started before you took the dash apart so somehow you messed something up. Look inside. See if wires were crossed or cut or broken or perhaps a connector isn't on tight.
Yes , Their was a RES diagnosis connector (passenger side) that I did connect when reassembled the dash. I disconnected the RES diagnosis connector and adjected the brake switch. the start button cycles properly now,
the Immobilizer still does not allow crank.
I have reset the vichle using both OBDII 4 and 13 and battery terminal shorting methods still no crank . the immobilizer light is flashing
