The 1995 Honda Accord, a popular choice for its reliability, often raises questions regarding its OBD system. A common query is the location of the OBD2 port. This guide clarifies the diagnostic system in the 1995 Honda Accord and provides instructions for locating the connector.
Understanding the 1995 Honda Accord’s Diagnostic System
It’s crucial to understand that the 1995 Honda Accord uses OBD1, not OBD2. OBD2 became standard in most vehicles starting in 1996. Therefore, you won’t find a standard 16-pin OBD2 connector in a 1995 Accord. Instead, it utilizes a 2-pin connector for diagnostic trouble codes (DTCs).
Locating the 2-Pin Connector
The 2-pin diagnostic connector in a 1995 Honda Accord is typically located under the glove box. More specifically, it’s usually found between the blower motor and the back of the glove box itself. Look for a blue, two-wire connector that isn’t connected to anything. This is your diagnostic port.
Retrieving Diagnostic Trouble Codes (DTCs)
While not as sophisticated as OBD2, the OBD1 system in the 1995 Accord allows you to retrieve engine trouble codes. This is done by “jumping” the two pins in the connector with a paperclip or a specialized jumper wire. Here’s how:
-
Locate the 2-pin connector: As described above, it’s under the glove box between the blower motor and the back of the glove box.
-
Turn the ignition to the “II” position: This is also known as the “ON” position, but without starting the engine.
-
Jump the connector: Use a paperclip or jumper wire to connect the two pins in the connector.
-
Observe the Check Engine Light (CEL): The CEL will begin to flash. Count the flashes and pauses to determine the DTCs. Long flashes represent tens, and short flashes represent ones. For example, two long flashes followed by three short flashes would indicate code 23.
Understanding the Maintenance Required Indicator
The 1995 Honda Accord also has a “Maintenance Required” indicator. This indicator is separate from the Check Engine Light and serves a different purpose. It’s designed to remind you of routine maintenance, such as oil changes. If this indicator turns red, it typically means service is overdue. Consult your owner’s manual for the recommended maintenance schedule. The reset procedure for this indicator varies depending on whether your Accord has a digital or analog odometer.
Addressing ABS Issues
Some 1995 Honda Accord owners experience issues with the Anti-lock Braking System (ABS), often indicated by a constantly illuminated ABS light. A common problem is the ABS actuator. If you hear a buzzing sound from under the hood, especially after starting the engine, it could indicate a problem with the ABS system. Check the ABS fluid level in the reservoir and consult a qualified mechanic for diagnosis and repair if needed.
Conclusion
While the 1995 Honda Accord doesn’t use OBD2, it still offers a diagnostic system through its 2-pin connector. Understanding the location of this connector and how to retrieve codes can be helpful for troubleshooting. Remember to consult a repair manual for specific DTC interpretations and recommended maintenance procedures for your 1995 Honda Accord.
