we got it out after taking out the glove compartment. what is at the other end of the wiring feed? there is no signal, does it mean the computer chip is broken too?
Customer reply replied 11 months ago
is the ECU a lexus part or is there a after market part?
Lexus Mechanic: David Craig, Auto Mechanic replied 11 months ago
