Reading Diagnostic Trouble Codes

How to Check for DTCs








1. If the IMA system indicator (A) stays on, turn the ignition switch OFF. Connect the HDS to the data link connector (DLC) (B) located under the passenger's side (2001-2005 models: driver's side) of the dashboard.
2. Short the SCS circuit to body ground using the HDS.
3. Turn the ignition switch ON (II).
4. Check the diagnostic trouble code (DTC): The IMA system indicator indicates a DTC by the length and the number of blinks, The indicator can indicate multiple problems by blinking separate DTCs, one after another. DTCs 1 through 9 are indicated by individual short blinks. DTCs 10 and above are indicated by a series of long and short blinks. One long blink equals 10 short blinks.
5. Refer to the DTC Troubleshooting, and begin the appropriate troubleshooting procedure.
