NOTE: Apply multipurpose grease to the mating surfaces on the knuckle and the O-ring during
reassembly.
 To prevent O-ring damage, the wheel speed sensor must be installed with the guide pin tool
(see step 5 on page 19-175).
10. Clean the mating surfaces of the brake disc and the inside of the wheel, then install the rear wheel.
11. Check the wheel alignment, and adjust it if necessary (see page 18-5).

Problems That Are Not System Faults
How a Diagnostic Trouble Code (DTC) is Set How to Troubleshoot DTCs
18-50TPMS
General Troubleshooting Information (cont’d)
 Tire Sealant
Fluid sealant used to repair a punctured tire can
damage the tire pressure sensor mounted on each
wheel. It can prevent the system from detecting the
correct tire pressure, which sets a DTC 11, 13, 15, or
17 even t hough the system is normal.
 Cold Weather When the weather is extremely cold, about 40 °C
( 40 °F) or colder, the output of the lithium battery in
each tire pressure sensor may drop far enough that
the control unit sets a DTC for low battery voltage (31,
33, 35, or 37) even t hough the system is normal.
 Non-TPMS Wheels (Including Spare Tire) Vehicles equipped with TPMS must use wheels made
for the system. Every TPMS wheel has an exclusive
mark; do not use any other type of wheel.
When a flat tire is replaced with the spare tire, the
TPMS indicator comes on (DTC 32, 34, 36, or 38)
because the system is no longer receiving the signal
from the flat tire’s transmitter.
This is not a problem with the spare tire.
 When the system detects a problem, the TPMS control unit sets a code, but shifts to fail-safe mode,
and does not alert the driver to low tire pressures.
 If the TPMS control unit loses power, or fails, the TPMS indicator comes on, but no DTCs are set.
 The memory can hold all the DTCs that could possibly be set. However, when the same DTC is
detected more than once, the most recent one
overwrites the previous one, so only the latest DTC of
each type is stored.
 DTCs are indicated in ascending order, not in the order they occurred.
 Set DTCs are stored in the EEPROM (nonvolatile memory), and cannot be cleared by disconnecting the
battery. To clear a DTC, connect the HDS (Honda
Diagnostic System) to the data link connector (DLC),
and follow the screen prompts. DTC troubleshooting procedures assume the cause of
the problem is still present and the TPMS indicator is
still on. Do not use a troubleshooting procedure unless
the system has set the DTC listed for it.
NOTE: For DTCs 11, 13, 15, and 17 (tire low pressure),
the TPMS indicator comes on only if the DTCs are
caused by a system problem rather than low tire
pressure.
1. Ask the client to describe the conditions when the indicator came on, and try to reproduce the same
conditions for troubleshooting. Find out if the client
checked and/or adjusted tire pressures since the
indicator came on.
2. If an indicator does not come on during the test- drive, check for loose terminals, poor contact due
to damaged terminals, etc. Before you start
troubleshooting.
3. After troubleshooting, repair and clear the DTCs, and test-drive the vehicle. Make sure no indicators
come on.
4. Check for DTCs from other control units that are connected via the F-CAN. If there are DTCs that are
related to the F-CAN, the most likely cause was that
the ignition switch was turned to ON (II) with the
TPMS control unit connector disconnected. Clear
the DTCs. Check for PGM-FI and TPMS codes, and
troubleshoot those first.

All four tire pressure sensor IDs must be memorized to
the TPMS control unit whenever you do any of these
actions: Replace the TPMS control unit.
 Replace the tire pressure sensor.
 Substitute a known-good wheel with tire pressure sensor.
NOTE:  To ensure the control unit memorizes the correct ID, the vehicle with the new sensor must be at least 3 m
(10 ft) away from other vehicles that have tire
pressure sensors.
 When doing a tire rotation, memorizing the sensors in not needed.
1. With the ignition switch in LOCK (0), connect the HDS to the data link connector (DLC) (A) located
under the driver’s side of the dashboard.
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the TPMS control unit. If it doesn’t,
troubleshoot the DLC circuit (see page 11- 204).
4. Select Sensor ID Learning from the mode menu on the HDS. 5. Turn on the TPMS tool by pressing the green select
button. Press the green select button until the
proper light sequence is illuminated as per the tool
user’s manual.
6. Hold the TPMS tool near one wheel, memorize the tire pressure sensor ID by following the screen
prompts on the HDS.
NOTE: If you turn the ignition switch to LOCK (0) before memorizing all four sensor IDs, the memorizing
ID is canceled.
 See the HDS Help menu for specific instructions.
7. Repeat step 6 for each wheel until all four sensor IDs are memorized. When all four IDs are
memorized, the low tire pressure indicator blinks.

Once the vehicle speed exceeds 45 km/h (28 mph), the TPMS control unit monitors all four tire pressure sensors and
the system function. If it detects low pressure in a tire, it alerts the driver by turning on the low tire pressure indicator.
If it detects a problem in the system, it turns on the TPMS indicator.
Mounted inside of the dash, the TPMS control unit receives wireless pressure sensor ID signals
every time the vehicle
speeds exceeds 45 km/h (28 mph). It also receives wireless signals from the transmitters for tire pressure and the
sensor condition, and it continuously monitors and controls the system. The TPMS control unit cannot directly
determine the position (location) of a tire pressure sensor(s) on the vehicle since it is a wireless system. TPMS sensor
locations will change during scheduled vehicle maintenance (tire rotation).
NOTE: To determine the actual location of each TPMS wheel sensor on the vehicle, do the tire pressure sensor
location procedure (see page 18-53). Once the tire pressure sensor locations are identified, write the sensor ID on the
side wall of the tire with a tire crayon to eliminate confusion.
Two indicators are in the gauge control module (tach): The low tire pressure indicator comes on when any tire
pressure is low, and the TPMS indicator that comes on only if there’s a problem with the system.
The low tire pressure indicator alerts the driver that a tire(s) pressure is low, but does not specify the tire(s) location.

Each sensor is an integrated unit made up of the tire valve stem, a tire pressure sensor, and a transmitter. The unit is
attached to the inside of the wheel, around the valve stem. The sensor transmits the internal tire information to the
control unit once every 60 seconds when the vehicle speed exceeds 45 km/h (28 mph). When the TPMS control unit
receives a tire pressure signal that is less than 175 kPa (1.8 kgf/cm , 25 psi) with 16 inch wheels, or 183 kPa (1.9 kgf/cm ,
27 psi) with 17 inch wheels, the TPMS control unit then turns on the low tire pressure indicator. When that tire’s
pressure is increased to more than 200 kPa (2.0 kgf/cm , 29 psi) with 16 inch wheels, or 210 kPa (2.1 kgf/cm , 30 psi)
with 17 inch wheels, and the vehicle is driven above 45 km/h (28 mph) the transmitter sends the tire pressure signal to
the control unit, and then the control unit turns the indicator off.
NOTE: Do not mix the TPMS tire pressure sensors or wheels with other TPMS types. Be sure to use the correct type
sensors and wheels for this system.
Sensor are active:
 When the wheel rotates over 45 km/h (28 mph), the sensor detects the momentum, switches the sensor to the normal function mode.
 The LF (low frequency) signal of the TPMS tool makes the sensor active even t hough the vehicle is stopped. The tire
pressure sensor goes into sleep mode when the acceleration sensor detects the wheel is stationary for 5 minutes or
more continuously.
The TPMS will not work unless TPMS type wheels are installed on the vehicle. There are three different types of
wheels used. The original equipment wheels have a ‘‘TPMS’’ mark (A) on them and are counterweighted (B) the
opposite of the tire pressure sensor (C), and counterbalance the weight of the sensor.
