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.

Schematic of a DTC code:

DTC is made up of 5 digits.

The figure below demonstrates the composition of a DTC. With this information it is easier to troubleshoot a DTC without knowing the description of the code.

X X X X X

Digit 1: B-Body, C-Chassis, P-Powertrain, U-Network

Digit 2: 0-SAE, 1-MFG

Digit 3: 1-Fuel and Air Metering
2-Fuel and Air Metering (Injectory Circuit)
3-Ignition Systems or Misfire
4-Auxiliary Emission Controls
5-Vehicle Speed Control and Idle Control System (ETC)
6-Computer Output Circuit
7-Transmission
8-Transmission

Digit 4,5: Fault (00-99)
