Understanding your vehicle’s On-Board Diagnostics system is crucial, especially when it comes to emissions testing or smog checks. For owners of classic cars like the 1996 Chrysler Intrepid, a common question arises: is the 1996 Chrysler Intrepid OBD2 compliant? This question is important because OBD2 compliance dictates how your car communicates diagnostic information and whether it can pass modern emissions tests.
This article will delve into the OBD2 compliance of the 1996 Chrysler Intrepid, providing clear information for owners, car enthusiasts, and anyone needing to understand this vehicle’s diagnostic system. We’ll explore what OBD2 compliance means for this model year, potential issues you might encounter during smog checks, and how to ensure your Intrepid meets necessary standards.
OBD2 Compliance for 1996 Vehicles: The Basics
1996 was a pivotal year for vehicle diagnostics. In the United States, 1996 marked the year that OBD2 (On-Board Diagnostics II) became mandatory for all new cars and light trucks. This standardization was implemented to improve vehicle emissions monitoring and provide technicians with better diagnostic capabilities. OBD2 systems use a standardized connector (SAE J1962) and a standardized set of diagnostic trouble codes (DTCs).
Generally, vehicles manufactured for the US market in 1996 should be OBD2 compliant. However, with early implementations of new standards, there can sometimes be nuances and exceptions. Therefore, specifically addressing the 1996 Chrysler Intrepid is essential.
The 1996 Chrysler Intrepid and OBD2: Is It Compliant?
According to information related to smog check procedures and vehicle diagnostic issues, the 1996 Chrysler Intrepid is indeed considered OBD2 compliant. However, it’s also listed as a vehicle with potential OBD system quirks that could affect smog testing, particularly BAR-97 EIS (Emission Inspection System) inspections used in some regions.
The original source material indicates that the 1996 Dodge Intrepid (related to Chrysler Intrepid) has a specific issue: “All monitors reset to incomplete upon every ignition key-off.” This means that the readiness monitors, which are self-tests the OBD2 system performs to verify emission control functionality, might reset each time the car is turned off.
This issue is significant for smog checks because readiness monitors need to be in a “ready” or “complete” state for the vehicle to pass the OBD portion of the test. If the monitors are constantly resetting, it can be challenging to get them into a ready state for inspection.
Understanding Readiness Monitors and Smog Checks
Readiness monitors are a core part of the OBD2 system’s function in emissions testing. They confirm that various emission control systems, such as the oxygen sensors, catalytic converter, and evaporative system, have been tested and are functioning correctly. For a 1996 gasoline vehicle, regulations typically allow for “Any one” incomplete monitor to still pass the OBD test. However, the constant resetting issue of the 1996 Intrepid can still present a hurdle.
During a smog check, the inspector will connect a diagnostic tool to the vehicle’s OBD2 port. The test includes several checks:
- Readiness Monitors: Checking the status of the readiness monitors.
- Malfunction Indicator Lamp (MIL): Ensuring the Check Engine light is functioning correctly (illuminates at key-on, engine-off (KOEO) and turns off when engine running (KOER) if no faults are present).
- Communication: Verifying that the diagnostic tool can communicate with the vehicle’s computer.
- Diagnostic Trouble Codes (DTCs): Checking for stored DTCs, which indicate system malfunctions. For 1996-1999 vehicles, Permanent Diagnostic Trouble Code (PDTC) checks are not applicable in BAR-97 tests.
For the 1996 Chrysler Intrepid, the key challenge lies in the readiness monitors resetting.
Addressing the 1996 Chrysler Intrepid’s Monitor Reset Issue
The provided documentation mentions a recall campaign #678 and TSB #18-005-01 to address the monitor reset issue in 1996 Chrysler and Dodge vehicles, including the Intrepid. These service actions are crucial for ensuring OBD system functionality for smog checks.
- Recall Campaign #678: This likely applied to California-certified vehicles originally sold in California.
- TSB #18-005-01: This Technical Service Bulletin may apply to both federally certified and California-certified vehicles, especially those initially sold in northeast states, and might come with a lifetime warranty.
For 1996 Chrysler Intrepid owners, especially if facing smog check difficulties, it’s highly recommended to:
- Check for Recall Completion: Verify if Recall Campaign #678 has been performed on your vehicle. You can usually do this by contacting a Chrysler dealership with your VIN (Vehicle Identification Number).
- Inquire about TSB #18-005-01: Ask a Chrysler service department about TSB #18-005-01 and whether it applies to your vehicle, especially if you are in or from the Northeast region of the US.
- Consult a Mechanic: If you are unsure or experiencing issues, consult a trusted mechanic familiar with classic cars and OBD2 systems. They can diagnose if the monitor reset issue is present and advise on necessary repairs or software updates, if available.
Tips for a Successful Smog Check with a 1996 Chrysler Intrepid
Even with potential OBD quirks, you can take steps to improve your chances of passing a smog check:
- Drive the Vehicle Before Testing: Drive your Intrepid for a reasonable distance and under various driving conditions (highway and city) before the smog check. This helps the readiness monitors to run and complete their tests.
- Avoid Clearing Codes: Do not clear any diagnostic trouble codes just before the test unless specifically advised by a mechanic after repairs. Clearing codes also resets readiness monitors, which can lead to a test failure if they are not completed in time for the inspection.
- Maintain Your Vehicle: Ensure your vehicle is well-maintained. Address any known engine or emission system issues before the smog check. A well-running engine is more likely to have all systems functioning correctly and monitors ready.
- Check for “Check Engine Light”: Ensure the Check Engine light is not illuminated before the test. If it is, have the codes read and addressed by a mechanic.
Conclusion: 1996 Chrysler Intrepid OBD2 and Smog Checks
In conclusion, yes, the 1996 Chrysler Intrepid is OBD2 compliant. However, owners should be aware of the potential issue where readiness monitors may reset upon each ignition key-off. Addressing this, possibly through historical recall campaigns or TSBs, is important for ensuring OBD system functionality and passing smog checks.
By understanding the specific nature of your 1996 Chrysler Intrepid’s OBD system and taking proactive steps, you can navigate smog checks successfully and keep this classic car running smoothly and legally. Remember to consult service professionals and utilize resources like manufacturer service bulletins to maintain your vehicle’s diagnostic and emission systems effectively.
