Problems That are Not System Faults
How a Diagnostic Trouble Code (DTC) is Set
How to Troubleshoot DTCs
18-49
• 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 though the system is normal.
• Cold Weather
When the weather is extremely cold - about
40 °F
(
40 °C) 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 though the system is normal.
• Non-TPMS Wheels
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 the system detects a problem, the TPMS
control unit sets a code, but shifts to fail-safe mode,
and will not alert the driver to low tire pressures.
• If the TPMS control unit loses power, or fails, the
TPMS indicator will come on, but no DTC will be 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), they 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. (NOTE: The TPMS indicator comes on for DTCs
11, 13, 15, and 17 only if the low tire pressure indication
is false, caused by a problem in the system.) Do not use
a troubleshooting procedure unless the system has set
the DTC listed for it.
1. Ask the customer to describe the conditions when
the indicator came on, and try to reproduce the
same conditions for troubleshooting. Find out if the
customer 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, clear the DTCs, and test-
drive the vehicle. Make sure no indicators come on.

1. With the ignition switch OFF, connect the HDS
(Honda Diagnostic System) to the 16P data link
connector (DLC) (A) under the driver’s side of the
dashboard.
2. Turn the ignition switch ON (II), and follow the
prompts on the HDS to retrieve any DTC(s) and
display them on the screen. Refer to the
troubleshooting procedure(s) for the DTC(s) listed.
NOTE: See the HDS Help menu for specific
instructions.
NOTE: You cannot clear the DTCs manually.
1. With the ignition switch OFF, connect the HDS to
the 16P data link connector (DLC) (A) under the
driver’s side of the dashboard.
2. Turn the ignition switch ON (II), and clear the
DTC(s) by following the screen prompts on the HDS.
NOTE: See the HDS Help menu for specific
instructions.

Memorizing the Tire Pressure Sensor ID
A
When a tire pressure sensor is replaced, the sensor ID
must be memorized by the TPMS control unit.
NOTE: To ensure the control unit memorizes the correct
ID, the vehicle with the new sensor must be at least 3 m
(10 ft) from any other TPMS pressure sensor not
installed on that vehicle.
After rotating the tires or replacing a tire pressure
sensor, drive the vehicle for at least 40 seconds at a
speed of 15 mph (24 km/h) or more, and all the sensor
IDs will be memorized automatically.
NOTE:
• When replacing the TPMS control unit, use the HDS
to memorize IDs.
• After the IDs are memorized, reduce the pressure in
all four tires to less than the appropriate specification,
and check to see that the four tire indicators come on.
The HDS can memorize the ID of a new tire pressure
sensor or a previously memorized ID.
1. With the ignition switch OFF, connect the HDS to
the 16P data link connector (DLC) (A) located under
the driver’s side of the dashboard.
2. Turn the ignition switch ON (II), and memorize the
ID of the tire pressure sensor by following the
screen prompts on the HDS.
NOTE:
• See the HDS Help menu for specific instructions.
• When replacing the TPMS control unit, use the
HDS to memorize IDs.
• After the IDs are memorized, reduce the pressure
in all four tires to less than the appropriate
specification, and check to see that the four tire
indicators come on.
