It' impossible and the scantool not working in a other car.

What the system for erase the 3 DTC code?

on this botom, i'ts a print screen of my computer

You don't say what car you have but the usual procedure is to disconnect the battery for 1 minute.
If the codes come back , you have problems that need checking

 

The car is ok

It's the codes in the scantool.
The codes are impossible to erase.

 

This isn't really 3rd Gen Camaro/Firebird related, but a Ford DTC 122 (EEC-IV) means low voltage at the throttle position sensor.

Is your check engine light on?

Google "ford EEC-IV trouble code 122" should help.

 

The codes is for my mustang
and I want to scan a Pontiac

just, I want to erase the codes into the scantool

 

You have a scanner problem ; not a car problem which we solve here

So search online for a owners manual for your scanner.

 

Yes it's a scanner problem
In the owners manual I dont have a solution
