red light stays on

Question

I have a 2010 toyota tundra. As i proceed thur the steps all is fine until I get to the,  turn the key to the on/run postion.

At which point the light blinks red.

Answer 1

It's not seeing key data. EIther you are using the grey valet key (which not allow programming, use the black key) or there's a problem with the IMMO DAta connections double check you IMMO Data connection.

 

You can try programming only the CAN-BUS if you like. This would confirm Can-Hi, Can-Low and igntion is properly detected. To program only the Can-Bus,

1. Release on BLUE
2. Plug in remain connectors
3. Turn ignition On
4. BLUE LED should flash here.
5. Turn ignition off

I'm having the same problem. I have a 07 tundra. I will say I don't have the DATA 1 and DATA 2 wires connected because I can't find the Ignition connectorwith the 7 pin white ignitino connector. I did find two connectors togther, 4 on one and 3 on the other but the empty hole was at the end. I also don't have to the PARKING wire connected because I can't find the 20 pin light switch harness. I think mine is a 22 pin.
