This post is intended to give an overview of how the TPMS works and some general tips on maintenence.Why TPMS?
The US government mandated the use of TPMS on vehicles as part of the TREAD act. The act was created in repsonse to the Firestone tire tread seperation issue of the late 90's which partly blames underinflated tires as the cause of blowouts. All passenger vehicles under 10,000lbs gross weight produced after Sept 2007 are required to have the system.
Canada: Although the TREAD act does not apply to Canadians, many of our vehicles have TPMS systems just the same.
What does it do?
Each wheel has a pressure sensor and transmitter located inside which is connected to the valve stem. The system monitors the pressure of the tires (some cars monitor the spare tire as well... the Rogue does not have this) and provides the driver a warning if any tire is underinflated. In the Rogue, the alarm threshold is 26psi and the vehicle must be travelling more than 16mph (25 km/h) before the pressure is checked.
Special Precautions:
- DO NOT use tire puncture sealant as it could damage the sensor.
- Removal of the OEM tires can damage the sensor. The sensor must be removed prior to dismounting the tire from the rim. There is a specific procedure for doing this and the dealer and tire shops familiar with TPMS systems should be able to do it properly.
The low tire pressure warning light in ON:
- Check the tire pressure using an accurate tire gauge and ensure they are inflated as per the sticker on the drivers side door jamb. The warning light should clear after driving for 5 min above 16mph (25km/h).
- If the outdoor air temperature drops suddenly, the tire pressure will drop and may trigger the TPMS. Re-adjust the tire pressures.
The low tire pressure warning light blinks for one minute then stays ON:
- If you substitite the OEM tires for aftermarket wheels or sometimes even the spare tire, you will get the low tire pressure warning light. The vehicle performance should not be affected while the light is ON, assuming you don't have a flat tire. The light will go off once the OEM tires are installed and after driving for 5 min above 16mph (25km/h).
- It is possible there is a malfunction in the system. Time to book a service appt with the dealer to check things out.
Can I install sensors on my new wheels?
Yes. New sensors can be purchased from Nissan and some aftermarket tire/wheel dealers. Cost is approx $80-100 USD each. You can also swap the sensors from the OEM wheels. Read special precautions above about sensor removal. Not all wheels will accept the sensors. Some aftermarket wheels may be labelled 'TPMS ready', but you will have to verify the sensor will properly fit. New sensors will have to be registered with the vehicle's computer to clear the TPMS light. This can only be done by a Nissan dealer.
What about tire rotation?
Tire rotation should not affect the sensors. Worst case, you will get the blinking TPMS and may have to make a trip to the dealer to clear the code.
Reading TPMS codes and clearing them
There is a simple procedure to perform a self diagnostic and clear the codes.
1) Turn IGN switch to ON.
2) Locate the TPMS warning check connector. It is a single loose wire with a connector located under the dash next to the steering column. It may be bundled with the OBDII diagnostic connector.
3) Using a suitable piece of bare wire inserted into the connector (a paperclip will do), momentarily ground the wire to the chassis.
NOTE: If you are uncomfortable doing this, then don't. You could damage your vehicle if the wrong wire is grounded.
4) The TPMS low tire pressure warning light will blink error codes as follows:
5sec. ON - 5sec. OFF
Long (1 sec) blink = First digit (2 blinks = 2)
Short (0.2 sec) blink = Second digit (ie 3 short blinks = 3)
There is a 2 second pause between multiple codes.The cycle will keep repeating starting with 5sec. ON
Codes:
15 - Front LH tire pressure drops to 26 psi or less.
16 - Front RH tire pressure drops to 26 psi or less.
17 - Rear RH tire pressure drops to 26 psi or less.
18 - Rear LH tire pressure drops to 26 psi or less.
21 - Data from front LH transmitter can not be receive.
22 - Data from front RH transmitter can not be receive.
23 - Data from Rear RH transmitter can not be receive.
24 - Data from Rear LH transmitter can not be receive.
31 - Checksum data from front LH transmitter is malfunctioning.
32 - Checksum data from front RH transmitter is malfunctioning.
33 - Checksum data from rear RH transmitter is malfunctioning.
34 - Checksum data from rear RH transmitter is malfunctioning.
5 short blinks - System is OK.
5) To clear the codes, turn the ignition OFF.
6) Drive 5 min above 16mph (25km/h) to see if the problem reoccurs.
This procedure does not guarantee you won't get the blinking TPMS warning again. If the problem reoccurs, the warning light will turn back ON.
