* Check Engine Light (CEL): If the check engine light is on, you'll need a code reader to retrieve the diagnostic trouble codes stored by the onboard computer. These code readers connect to a diagnostic port (usually under the dash) and display the codes. You can't simply reset the CEL; you must address the underlying issue causing the code to be set. Once the problem is fixed, the light may turn off after a few driving cycles, or you might need to use a code reader to clear the code.
* Other Issues: If you're having problems unrelated to the CEL, like a malfunctioning power window or radio, resetting any related computer modules would involve disconnecting the battery for a short period (around 30 minutes). This might reset some learned parameters, but it won't necessarily "reset codes" in the same way a modern OBD-II system does.
Important Considerations:
* Professional Diagnosis: For persistent or serious problems, taking your LeBaron to a mechanic familiar with older Chrysler vehicles is recommended. They'll have the proper tools and expertise to diagnose the problem accurately.
* OBD-I System: The 1994 LeBaron uses an OBD-I system, which is significantly less sophisticated than the OBD-II systems found in later vehicles. This means getting and interpreting codes can be more challenging.
* Battery Disconnect: Remember to disconnect the negative terminal of your battery first when disconnecting it to avoid accidental short circuits. Consult your owner's manual for more detailed instructions.
In short, there's no simple "reset codes" button. If a light is on or something isn't working, you need to investigate the cause, fix the problem, and potentially clear the code using a suitable code reader if necessary.
