Question

2010 tundra with g key 

I’m trying to program key override all 
The unit is not programming the red light comes on solid with connections, truck starts for a second and shuts off, light stays solid even after 5 minuets. 

all the wires seem to be connected properly 

Using connection 20 page 14 and programming 3 page 17 of installation guide-6 wire connection 4 wire connection then power 4 wire plug. Not using the data wires just power/ground 

need a little help 

thanks

 

 

Answer 1

The vehicle should stay running when programming, if you disconnect all connectors except the 4 pin white connector from the key override all and start with key, does the truck stay running ?

Answer 2

as you mentionned, when programming, insert 4-pin white, 6-pin white and power last

if you still getting issues here, there is an issue with the connections. Since the car is shutting, check the IMI.
