![]() Most Nissans require the use of an enhanced/factory scan tool or dedicated TPMS tool, unlike some domestic systems where a relearn procedure can be performed by just pressing a few buttons on a key fob. Always make sure the sensor’s body is parallel to the wheel. Changes in the mounting position of the sensor can interfere with the activation tool as well as the sensor’s transmission. Sensors are sensitive to how they are installed on the wheel. Never assume that the failure of a sensor to register means that the sensor has failed. The sensor may also transmit battery information if the voltage is below a specified level. ![]() The receiver knows where the sensor is located by the transmitted ID number and matches it to the number stored in the receiver module. The sensors have small accelerometers that trigger operation when the vehicle is moving. The sensor transmits the ID and pressure information at specified intervals or if a rapid deflation event is detected. Most Nissan TPMS systems use a single receiver that detects signals from the four sensors (five if the spare tire has a sensor). Nissan uses TPMS sensors from TRW, Continental, Schrader and Pacific. Retrieving this data requires a scan tool that can communicate with the Body Control Module (BCM). However, this will not indicate sensor malfunctions like low battery voltage, transmitter loss of signal or another system malfunction. The pattern of the flashing can indicate if a specific sensor is not activated (ID not present in the module). If the system is malfunctioning, the light will flash for one minute and then stay on. The first procedure should be to inflate the tires to the specified pressure and drive at speeds above 16 mph for at least three minutes to turn the light off. If you get a Nissan in your shop where the light stays illuminated, it is an indication that the system is operating normally and has detected a low tire. I know the more expensive tools will do this like the VT56 but I need something a lot cheaper as I will not use it very often.The most common complaint you will get in your shop is low inflation. Will I also need an activation tool to wake the sensors up, or because they are both identical OEM units off working cars are they already activated? What tool is available to write those ID codes back into the ECU? (Remember I am just swapping the TP sensors from one vehicle to the other) What tool is available to read the TP Sensor ID codes from the ECU? ![]() I have read every thread I can find but can't get an answer to these questions: Now from researching, I have found that the 2013 Altima stores the TP sensor ID codes in the ECU. This of course triggered the TPMS light to come on in both cars. So I decided to swap the rims between the cars with the added benefit that my SV rims were actually in better shape. The tires on the SL were also Michelin, but were the cheaper ones, and they are just about worn out. ![]() I had put a set of Michelin tires on the SV last year that had about 20,000 miles on them. I immediately went out and I found a 2013 Altima SL with 92,000 miles on it, full service history (women owned) and bought it. My SV got rear ended a couple of weeks ago and was totaled by the person who hit me's insurance company. ![]() I, for a short time, have two 2013 Altimas a SV and an SL. Dredging up this old thread to ask a question related to it. ![]()
