As a seasoned auto repair expert at cardiagnosticnearme.com, I understand the importance of quickly locating your vehicle’s diagnostic port. If you’re trying to find the OBD2 location on your 1995 Honda Accord, you’ve come to the right place. Let’s clarify something right away: your 1995 Honda Accord is actually equipped with an OBD1 system, not OBD2. This is a common point of confusion, as the OBD2 standard became mandatory in the USA for vehicles manufactured in 1996 and later.
Understanding OBD1 in Your 1995 Honda Accord
While OBD2 is the standard we see in most modern cars today, vehicles from the mid-1990s, like your ’95 Accord, often used the earlier OBD1 system. OBD1, or On-Board Diagnostics generation 1, is an earlier diagnostic system that, while serving a similar purpose to OBD2 (monitoring vehicle systems), is implemented differently.
The key difference for you as a car owner is the diagnostic port itself and the method for retrieving trouble codes. OBD2 ports are standardized 16-pin connectors, whereas OBD1 systems used various connectors specific to the manufacturer.
Locating the OBD1 Diagnostic Connector on a 1995 Honda Accord
So, if you’re looking for the diagnostic port on your 1995 Honda Accord, you won’t find the familiar OBD2 port. Instead, you need to locate the OBD1 connector. Here’s where to look:
The OBD1 port on a 1995 Honda Accord is typically located under the glove box on the passenger side.
To find it precisely:
- Go to the passenger side of your vehicle.
- Locate the glove box.
- Look underneath the glove box, towards the center console area. You’ll need to get down and look upwards.
- Search for a small, usually blue, 2-pin connector. This connector is often not connected to anything and hangs freely by wires. It’s typically positioned between the blower motor for the air conditioning and the back of the glove box compartment.

This 2-pin connector is your gateway to accessing the diagnostic information from your 1995 Honda Accord’s computer.
Retrieving Diagnostic Trouble Codes (DTCs) from a 1995 Honda Accord
Since your ’95 Accord is OBD1, you can’t use a standard OBD2 scanner directly. However, you can still retrieve diagnostic trouble codes (DTCs) using a simple “paper clip” method. This involves using a paper clip to jump the two pins in the connector, and then reading the codes through the Check Engine Light (CEL) flashes on your dashboard.
Here’s how to do it:
- Locate the 2-pin OBD1 connector as described above.
- Get a paper clip and bend it into a U-shape.
- Turn off the ignition.
- Insert the bent paper clip into the two terminals of the blue connector. This is essentially “jumping” the pins.
- Turn the ignition key to the “ON” position (position II), but do not start the engine.
- Observe the Check Engine Light (CEL) on your instrument cluster. The CEL will begin to flash in patterns.
Decoding the Flashes:
The flashes are used to communicate the trouble codes. A code is represented by a series of long and short flashes.
- Long flashes represent the digit ’10’.
- Short flashes represent the digit ‘1’.
For example, code 12 would be represented by one long flash followed by two short flashes. Codes are typically two digits. There will be a pause between codes, and a longer pause between the repetition of all stored codes. Record all the codes flashed by the CEL. You will need to look up these codes for a 1995 Honda Accord OBD1 system to understand the issue.
Addressing Maintenance and ABS Indicator Lights
The original forum post also mentions “Maintenance Required” and ABS lights. It’s important to differentiate between these:
-
“Maintenance Required” Indicator: This light, often found in older Honda models, is usually a reminder for routine servicing, like oil changes, based on mileage intervals. It’s not directly related to diagnostic trouble codes. Resetting this light usually involves a specific procedure, which may vary depending on the exact instrument cluster type. For some models, it involves pressing and holding a reset button on the instrument cluster while turning the ignition on. However, as the original poster noted, this may not always work, and could indicate a faulty reset switch or a different type of system.
-
ABS Light: If your ABS light is on, it indicates a problem with the Anti-lock Braking System. This is a more serious issue related to vehicle safety and will likely store a diagnostic trouble code. The buzzing noise mentioned in the original post, especially after brake pad replacement, could be related to the ABS actuator, a common issue in Accords of this era. Low ABS fluid or issues within the ABS hydraulic system could also be culprits.
Conclusion
While your 1995 Honda Accord doesn’t have an OBD2 port, accessing its diagnostic system is still possible using the OBD1 connector and the paper clip method to retrieve codes. Understanding the location of this connector and how to interpret the Check Engine Light flashes is the first step in diagnosing potential issues.
Remember, while you can retrieve the codes yourself, diagnosing the root cause and performing repairs often requires specialized knowledge and tools. If you are unsure about interpreting the codes or addressing any mechanical issues, it’s always recommended to consult a qualified mechanic. They can accurately diagnose the problem and ensure your 1995 Honda Accord remains safe and reliable on the road.
