Instead of jumper wires, you'll likely need a method that involves a code reader designed for that specific vehicle year's system or a scan tool capable of reading pre-OBDII codes. Attempting to use jumper wires to check for codes could damage the vehicle's computer.
Here's why a simple jumper method is unlikely to work and what you should do instead:
* Pre-OBDII Systems: 1993 vehicles often used a less standardized system for diagnostic trouble codes (DTCs). The method for retrieving these codes varied significantly by manufacturer and even model. A simple jumper wire technique for a later OBDII car won't apply.
* No Standardized Connector: Unlike the standardized OBDII connector, the diagnostic connector on your 1993 Dodge Shadow likely had a different configuration.
* Potential for Damage: Connecting jumper wires to incorrect pins can cause damage to the vehicle's computer or other electrical components.
Recommendation:
1. Obtain a scan tool: This is the most reliable approach. Look for a scan tool specifically designed for pre-OBDII vehicles, or one that is explicitly compatible with your 1993 Dodge Shadow's system. Many auto parts stores offer diagnostic services, too.
2. Consult a repair manual: A repair manual specific to your 1993 Dodge Shadow 2.2L will provide detailed instructions on how to properly diagnose trouble codes, including the location of the diagnostic connector and any specialized procedures. This is your best bet to avoid damage.
Attempting to find the correct pins without a proper repair manual is risky. The cost of a scan tool or the service at an auto parts store is much less than potential repair bills from damaging your car's computer.
