INTRODUCTION
Beginning with some 2007 models, Honda is using a second type of TPMS (tire pressure monitoring system) that does not use initiators like the 2006
and earlier
TPMS.
All TPMS sensors:
^
Are mounted on the inside of the rim, connected to the valve stem.
^
Use a wireless transmission to send tire pressure and temperature information to the TPMS unit.
^
Use non-replaceable batteries. To save battery life, the sensors turn on only when the vehicle is being used.
Initiator-Type TPMS (Location-Type TPMS)
*The first type of TPMS (all vehicles through 2006) uses initiators mounted above each wheel. When you turn the ignition switch to ON (II), the
initiators send out a low frequency signal to turn on the TPMS sensors. The initiator, in conjunction with the TPMS control unit, determines the tire
location. For example, if the right front tire is low on air, the customer sees the low tire pressure indicator and an indiction that the right front tire is low
on pressure. The initiator-type TPMS, or location-type TPMS (in the HDS), is used on the 2005-08 Pilot, the 2006-08 Ridgeline, and the 2005-08
Odyssey Touring models.*
Initiator-less TPMS (No Location-Type TPMS)
The new TPMS does not use initiators. The TPMS sensors have a built-in acceleration sensor that turns on the TPMS sensors when the vehicle speed
reaches about 25 mph. Without an initiator, the TPMS control unit cannot determine tire location. For example, if the right front tire is low on air, the
customer sees only the low pressure indicator and must check all four tires to find the problem tire. During diagnosis, the TPMS control unit provides a
code for each tire.
NOTE:
^
During diagnosis, the TPMS control unit gives a tire number, but you need to do the sensor position check to find the location of the tire number.
^
Use with HDS software version 2.011.010 or later. The initiator-less TPMS, or no location-type TPMS, is used on vehicles affected by this
bulletin.
