SUBJECT VEHICLE: 2005-10 Nissan Frontier.
SENSOR IN TIRE? No (sensors/transmitters are installed in wheels).
RESET PROCEDURE? Yes (whenever an old sensor has been replaced).
SPECIAL TOOLS NEEDED? Yes (CONSULT-II and CONSULT-II CONVERTER, plus a Transmitter Activation Tool J-45295).
When the Nissan Frontier is moving at speeds of above 20 mph, its tire pressure monitoring system (TPMS) receives signals sent from the transmitter installed in each wheel and gives alarms when tire pressure levels drop.
When the system detects low inflation pressure or another unusual symptom, the warning light in the instrument cluster comes on.
If the system detects that air pressure has dropped to 28 psi, it will sound a buzzer for 10 seconds and a “FLAT TIRE” warning message will appear.
To remove an old sensor, follow these steps:
1. Deflate the tire. Unscrew the transmitter retaining nut and allow the transmitter to fall into the tire.
2. Place the tire and wheel assembly on the tire changer and break both beads. Ensure that the transmitter remains at the bottom of the tire while breaking the bead.
3. Turn the tire so the valve hole is at the bottom. Lift the tire onto the turntable and position the valve hole 270 degrees from the mounting/demounting head.
4. Lubricate the tire well, and remove the top side of the tire. Reach inside the tire and remove the transmitter.
5. Remove the second side of the tire.
Now you’re ready to install the replacement sensor by following these steps:
1. Place the first side of the tire onto the rim.
2. Apply suitable silicone lubricant to the new seal. Install the seal on the sensor.
3. Mount the transmitter on the rim and tighten the nut to 49 in.-lbs.
4. Place the wheel on the tire machine’s turntable. Make sure that the transmitter is 270 degrees from the mounting/demounting head.
5. Lubricate the tire. Install the second side of the tire.
6. Inflate the tire and balance the tire/wheel assembly.
At this point, you may proceed with registering the new tire pressure sensor.
Whenever a spare tire is mounted or a tire pressure sensor has been replaced, the new sensor must be registered. A Nissan CONSULT-II and CONSULT-II CONVERTER must be used to register the new sensor.
It is important to note that if a new sensor has been installed, it will be in “sleep mode.”
To wake up the sensor, you must follow these steps:
1. With the Transmitter Activation Tool (J-45295) pushed against the front left transmitter, press the button for five seconds. With the ignition switch in the ON position, the transmitter must be woken up.
2. When the vehicle’s Body Control Module (BCM) has finished assigning each tire ID, the BCM flashes the hazard warning lights and sends a flashing indicator status.
Make sure the low tire pressure warning light goes out after all of the transmitters have been woken up.
Here’s how you perform the ID registration process with the CONSULT-II and CONSULT-II CONVERTER:
1. With the ignition in the OFF position, connect the CONSULT-II and the CONSULT-II CONVERTER to the Data Link Connector (DLC).
2. Turn the ignition to the ON position.
3. Select “START (NISSAN BASED VHCL).”
4. Touch “BCM” on the “SELECT SYSTEM” screen.
5. Select “AIR PRESSURE MONITOR” on the “SELECT WORK ITEM” screen.
6. Select “WORK SUPPORT” on the “SELECT DIAG MODE” screen, and then select “ID REGIST.”
7. With the Transmitter Activation Tool (J-45295) pushed against the front left transmitter tire air valve, press the button for five seconds.
