- Engine Temperature: The engine should be at normal operating temperature (160-203°F or 70-95°C). Drive your car for at least 30 minutes to achieve this. Warming up the car in the garage is generally insufficient.
- Electrical Load: Turn off all accessories, including the air conditioning, rear window defogger, radio, and heater blower. These can put a load on the engine and affect the throttle plate positioning.
- Vehicle Position: Ensure the front wheels are in the neutral position, pointing straight ahead.
- No Error Codes: Ensure there are no active error codes related to the mass airflow sensor, manifold absolute pressure, or incorrect idle speed. Clear any existing codes before proceeding.
3.2. Battery Reset (Optional but Recommended)
Disconnecting the negative battery terminal for 30 seconds can reset the ECU and clear any learned settings. This step is optional but can help ensure a clean start for the IAVL process.
3.3. Safety Precautions
- Ensure the vehicle is parked on a level surface and the parking brake is engaged.
- Wear appropriate safety gear, such as gloves and eye protection.
- Work in a well-ventilated area, especially when using throttle body cleaner.
- Keep a fire extinguisher nearby in case of emergencies.
4. Step-by-Step Guide to Autel Electronic Throttle Pairing on a 2007 Maxima
Follow these steps meticulously to perform the autel electronic throttle pairing correctly:
4.1. Accelerator Pedal Released Position Learning
This step teaches the ECU the position of the accelerator pedal when it’s fully released.
- Release Pedal: Make sure the accelerator pedal is fully released.
- Ignition ON: Turn the ignition switch to the “ON” position and wait at least 2 seconds.
- Ignition OFF: Turn the ignition switch to the “OFF” position and wait at least 10 seconds.
- Ignition ON Again: Turn the ignition switch to the “ON” position again and wait at least 2 seconds.
- Ignition OFF Again: Turn the ignition switch to the “OFF” position again and wait at least 10 seconds.
4.2. Throttle Valve Closed Position Learning
