On all 1996-97 minivans, you can access the DTC's in the following two ways:
On all 1998-99 minivans, the only way to retrieve DTC's is by using a DRB® or equivalent scan tool.
Keep in mind that DTC's are the result of a system or circuit failure, but may not directly identify the failed component(s).
READING DTC'S USING A SCAN TOOL
- Connect Chrysler's Diagnostic Readout Box (DRB) or equivalent scan tool to the data link (diagnostic) connector. This connector is located at the lower edge of the instrument panel, near the steering column.
Always make sure to follow the manufacturer's instructions when using a scan tool.
- Turn the ignition switch ON , and access the Read Fault screen with the scan tool.
- Record all of the DTC's and freeze frame information shown on the scan tool.
- Once the repairs have been completed, erase the trouble codes. Once the codes have been erased, check that the scan tool displays normal.
READING CODES USING MIL (CHECK ENGINE) LAMP
See Figures 1 and 2
Be advised that the MIL, CHECK ENGINE, or SERVICE ENGINE SOON light can only perform a limited number of functions, and it is a good idea to have the system checked with a scan tool to double check the circuit function.
- Within a period of 5 seconds, cycle the ignition key ON - OFF - ON - OFF - ON .
- Count the number of times the MIL (check engine or service engine soon lamp) on the instrument panel flashes on and off. If it is not located at the bottom of the instrument cluster, then it is located in the information center on the dashboard above the instrument cluster.
The number of flashes represents the trouble code. There is a short pause between the flashes representing the 1st and 2nd digits of the code. Longer pauses are used to separate individual 2-digit trouble codes.
An example of a flashed DTC is as follows:
