Experiencing a persistent TPMS (Tire Pressure Monitoring System) warning light after changing your wheels on your 2007 or 2008 Infiniti G35x can be frustrating. Perhaps you’ve upgraded your rims or, like many, installed wheels from a newer Infiniti model, such as G37 wheels. While these modifications can enhance your vehicle’s appearance and performance, they sometimes lead to TPMS sensor incompatibility. If you’ve found yourself in this situation, especially after installing 2010 G37 wheels with their OEM TPMS sensors on your 2007 G35x, you might be wondering how to resolve the dreaded TPMS light. Dealerships may express uncertainty about compatibility, and professional resets can be costly. Fortunately, there’s a DIY method that leverages your Infiniti’s OBD2 system and the 2007 Pid Tpms G35x Infiniti Obd2 interface to relearn new TPMS sensors. This guide provides a comprehensive, step-by-step approach to resetting your TPMS at home, saving you time and money.
Understanding TPMS and Why Resetting is Needed
The Tire Pressure Monitoring System in your Infiniti G35x is designed to alert you when tire pressure drops significantly, enhancing safety and fuel efficiency. Each TPMS sensor, typically located within the wheel, transmits pressure readings to your vehicle’s computer. When you change wheels, especially if the new wheels have different TPMS sensors or sensors that haven’t been recognized by your car’s system, the TPMS warning light can illuminate.
In the case of installing 2010 G37 wheels on a 2007 G35x, the issue arises because, while both models use Schrader TPMS sensors (common in Nissan/Infiniti vehicles), the specific sensor IDs might not be automatically recognized. The car’s computer needs to “learn” the new sensor IDs to correctly monitor tire pressure. This is where the TPMS reset procedure comes in, allowing you to manually initiate the learning process through the OBD2 interface, specifically using the 2007 pid tpms g35x infiniti obd2 communication protocol.
Step-by-Step Guide to Resetting Your Infiniti G35x TPMS
This DIY method involves using a paper clip or wire to ground a specific pin in the TPMS interface plug, which is located near the OBD2 port. It’s crucial to follow these steps precisely for a successful TPMS reset.
Preparing Your Vehicle and Tools
Before starting, ensure you have the following:
-
Correct Tire Pressures: You’ll need to adjust your tire pressures to specific values as part of the reset process. Have a tire pressure gauge and an air compressor handy. The required pressures are:
- Front Left (LH): 34 psi (240 kPa)
- Front Right (RH): 31 psi (220 kPa)
- Rear Right (RH): 29 psi (200 kPa)
- Rear Left (LH): 26 psi (180 kPa)
- Note: These pressures are temporary and for the reset procedure only. You will reinflate to your vehicle’s recommended pressures afterward.
-
Paper Clip or Wire: A small paper clip or a short length of wire will be used to ground the TPMS interface plug.
-
Grounding Point: Identify a metal part under your dashboard that can serve as a ground. The steering column is often a convenient and reliable grounding point.
-
OBD2 Port and TPMS Interface Plug Location: The TPMS interface plug is a white, 2-pin female connector attached to the OBD2 wire loom. It’s typically located under the dashboard on the driver’s side, near where your left knee would be. It might be taped to the OBD2 wiring. Locate this white connector; it will have a single wire (usually white or yellow) going into it. This is the connector you’ll be working with to access the 2007 pid tpms g35x infiniti obd2 system for reset.
The TPMS Reset Procedure
There are slightly different variations of this procedure. We will outline two methods, and you can try the first one. If it doesn’t work, proceed to the second method.
Method 1: Key ON, Engine OFF Method
-
Set Tire Pressures: Adjust your tire pressures to the exact values specified in the “Preparing Your Vehicle and Tools” section.
-
Locate TPMS Interface Plug: Find the white 2-pin TPMS interface plug near your OBD2 port.
-
Prepare Paper Clip/Wire: Insert one end of your paper clip or wire into the single wire slot of the TPMS interface plug.
-
Key ON, Engine OFF: Insert your key into the ignition and turn it to the “ON” position (just before starting the engine). If you have a push-button start, press the start button twice without pressing the brake pedal.
-
Grounding Sequence: Within 10 seconds of turning the ignition to “ON,” tap the other end of your paper clip/wire against a ground (like the steering column) 6 times within 10 seconds. Ensure you are making a good ground connection.
-
TPMS Light Confirmation: If successful, the TPMS warning light on your dashboard will begin to flash slowly. This indicates you have entered TPMS relearn mode. If it flashes rapidly or stays solid, turn the ignition OFF and repeat from step 4, ensuring good ground connections and correct timing.
-
Start Engine and Drive: Once the TPMS light is flashing slowly, step on the brake and start the engine. Do not turn the ignition OFF.
-
Drive to Relearn: Drive your Infiniti G35x at speeds above 25 mph (40 km/h). Continue driving until the TPMS warning light turns off. This may take up to 10 minutes or more.
-
Reinflate Tires: Once the TPMS light goes out, it may reappear shortly due to the intentionally low tire pressures. Reinflate all tires to your vehicle’s recommended pressures (found on the sticker inside your driver’s side doorjamb). The TPMS light should remain off after reinflating.
Method 2: Engine Running Method
If Method 1 doesn’t work, try this variation:
-
Set Tire Pressures: Adjust your tire pressures as specified earlier.
-
Locate TPMS Interface Plug and Prepare Wire: Same as Method 1.
-
Start Engine: Start your Infiniti G35x engine and let it idle.
-
Grounding Sequence: Tap the end of your paper clip/wire against a ground 5 times within 10 seconds.
-
TPMS Light Confirmation: The TPMS warning light should start flashing slowly, indicating relearn mode.
-
Drive to Relearn: Drive your vehicle above 25 mph (40 km/h) for about 15 minutes until the TPMS light turns off.
-
Reinflate Tires: Reinflate your tires to the correct pressures.
Troubleshooting Tips
- Fast Flashing TPMS Light: If the TPMS light flashes rapidly after the grounding sequence, it indicates an error. Check your connections, ensure you are using a proper ground, and repeat the procedure.
- No Flashing Light: If the TPMS light doesn’t flash at all after grounding, double-check your ground connection, the connection to the TPMS interface plug, and the timing of your grounding taps. Ensure you are tapping within 10 seconds of turning the ignition ON (for Method 1) or starting the engine (for Method 2).
- Persistent TPMS Light: If the light remains on even after driving and reinflating tires, re-check your tire pressures and repeat the entire reset procedure. If the issue persists, the TPMS sensors themselves might be incompatible or faulty, and you may need to consult a tire shop or dealership.
Important Considerations and Notes
- Schrader Sensors: This DIY reset method is generally effective for Schrader brand TPMS sensors, which are commonly used in Nissan and Infiniti vehicles. If your aftermarket wheels use different sensors, compatibility might vary.
- Dealer vs. DIY: While dealerships have diagnostic tools to reset TPMS systems, this DIY method offers a free and convenient alternative.
- Safety First: Always perform vehicle maintenance in a safe environment. Be cautious when working under the dashboard and around electrical components.
- Tire Pressure Accuracy: Precise tire pressures are crucial for initiating the relearn process. Use an accurate tire pressure gauge.
By following these steps carefully, you should be able to reset the TPMS system on your 2007-2008 Infiniti G35x after installing new wheels, potentially even those from a 2010 G37. This DIY approach leverages the 2007 pid tpms g35x infiniti obd2 interface to communicate with your vehicle’s computer and relearn the new TPMS sensor IDs, resolving the annoying TPMS warning light and ensuring your tire pressure monitoring system functions correctly.
