How to display DTC "Diagnostic Trouble Codes" on Dodge Challenger.

Get in the car, close the door. Perform the following steps fairly quickly (in less than 3 seconds) :

Turn key to ON
then back to ACC
then to ON
then back to ACC
then to ON

If there are any stored codes, they will appear immediately, in place of the odometer. For instance an "INTAKE AIR TEMPERATURE SENSOR CIRCUIT HIGH" error will set a code of P0113.
