Wheel Lift Equipment
This is an acceptable way of towing the
vehicle.
Sling-type Equipment
This method of towing
the vehicle is unacceptable.
Manual Transmission
Automatic Transmission
1-13
The tow truck uses two
pivoting arms that go under the tires (front or rear) and
lift them off the ground. The other two wheels remain
on the ground.
The tow truck uses metal
cables with hooks on the ends. These hooks go around
parts of the frame or the suspension, and the cables lift
that end of the vehicle off the ground. The vehicle’s
suspension and body can be seriously damaged if this
method of towing is attempted.
If the vehicle cannot be transported by a flat-bed, it
should be towed with the front wheels off the ground. If
the vehicle is damaged, and must be towed with the
front wheels on the ground, or with all four wheels on
the ground, do this:
 Release the parking brake.
 Shift the transmission to neutral.
 Leave the ignition switch in ACCESSORY (I) so the steering wheel does not lock.
 Make sure all accessories are turned off to minimize current battery draw.
 Release the parking brake.
 Start the engine.
 Shift to D, then to N.
 Turn off the engine.
 Leave the ignition switch in ACCESSORY (I) so the steering wheel does not lock.
 Make sure all accessories are turned off to minimize current battery draw.
It is best to tow the vehicle no farther than 80 km
(50 miles), and keep the speed below 55 km/h (35 mph).  Improper towing preparation will damage the
transmission. Follow the above procedure exactly. If
you cannot shift the transmission or start the engine
(automatic transmission), the vehicle must be
transported on a flat-bed.
 Trying to lift or tow the vehicle by the bumpers will cause serious damage. The bumpers are not
designed to support the vehicle’s weight.

The TPMS (tire pressure monitoring system) has the
low tire pressure indicator and the TPMS indicator.
 If the system detects low pressure in any of the four tires, the low tire pressure indicator comes on.
 When this happens, inflate the air and test-drive the vehicle at 45 km/h (28 mph) or more for at least 1
minute, and the low tire pressure indicator will go off.
 If the control unit detects a problem in the system during an indication of low tire pressure, it turns off
the low tire pressure indicator, stores the DTC(s), and
turns on the TPMS indicator.
 If a problem is detected in the system, the TPMS indicator comes on.
 If low tire pressure and a problem in the system are detected, only the TPMS indicator comes on.
If the system is OK, the TPMS indicator and the low
tire pressure indicator should come on when you turn
the ignition switch to ON (II), and then go off 2
seconds later. If they don’t, there is a problem with
the system. If the system detects low pressure in any of the four
tires, the low tire pressure indicator comes on, and the
control unit sets one or more of these codes: DTC 11,
13, 15, 17. When the tire pressure returns to normal,
and the TPMS control unit receives the normal pressure
signal from the tire pressure sensor, the control unit
turns off the indicator. However TPMS control unit still
retains the DTC(s).
NOTE: It is necessary to test-drive the vehicle at
45 km/h (28 mph) or more for at least 1 minute so that
tire pressure sensor transmits the signal.
The pressures increase slightly as the temperature in
the tires rises during driving.
Pressures can also increase or decrease slightly with
changes in outside air temperature.
A temperature change of about 10 °C (18 °F) changes
tire pressure by about 10 kPa (0.1 kgf/cm , 1.5 psi). If the
temperature drops, tire pressure could decrease just
enough to turn on the low tire pressure indicator, but
later, the tire temperature could increase enough to
turn the indicator off. To resolve a complaint of such
intermittent indications, confirm and clear the stored
DTC(s) and check the tire pressures. Then explain to the
client how temperature changes can affect the system.

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.

DTC Troubleshooting
Tire Low Air Pressure
NOTE: If low tire pressure is detected, the control unit
sets one or more of these DTCs, and turns on the low
tire pressure indicator. If the low tire pressure indicator
comes on because of a low tire pressure, and the client
corrects it before bringing the vehicle in, the DTCs will
be stored, but the indicator turns off. 1. Turn the ignition switch to LOCK (0).
2. Make sure the tires are inflated to the specified tire pressure listed on the doorjamb sticker.
3. Test-drive the vehicle at 45 km/h (28 mph) or more for at least 1 minute.
The system is OK at this time. Check for and
repair the cause of air loss.
Go to step 4.
4. Check for DTCs with the HDS. 5. Note the tire pressure sensor(s) number by the
indicated DTC.
11 No. 1
13 No. 2
15 No. 3
17 No. 4
6. Do the tire pressure sensor location procedure to determine the affected tire location and relate it to
the tire pressure sensor number (see page 18-53).
7. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4 AIR PRESSURE in the TPMS DATA LIST with the HDS,
and compare it with the actual measured tire
pressure.
Go to step 8.
Replace the appropriate tire pressure sensor
(see page 18-76).
8. Clear the DTC with the HDS.
9. Test-drive the vehicle at 45 km/h (28 mph) or more for at least 1 minute.
10. Check for DTCs with the HDS.

Symptom Troubleshooting
NOTE: Check for gauge DTCs with the HDS (see page
22-3). If gauge DTCs are stored, troubleshoot those
DTCs first.
1. Turn the ignition switch to ON (II).
2. Check the low tire pressure indicator for several seconds when the ignition switch is turned ON (II).
Go to step 3.
Do the troubleshooting for the gauge control
module (see page 22- 241). If necessary, substitute a
known-good gauge control module (see page
22-277), and recheck.
3. Test-drive the vehicle at 45 km/h (28 mph) or more for at least 1 minute.
4. Stop the vehicle, and lower the pressure in each tire until the low tire pressure indicator comes on
(see table).
NOTE: Reinflate the tire before continuing to the next tire.
 After noting whether the low tire pressure indicator came on, make sure it goes off when
you reinflate the tire before proceeding to the
next tire.
 If 5 minutes has passed since finishing the last test-drive, reactivate the appropriate tire
pressure sensor using the TPMS sensor initializer
tool (see page 18-53).
16 inch wheels 175 kPa (1.8 kgf/cm , 25 psi)
17 inch wheels 183 kPa (1.9 kgf/cm , 27 psi)
The system is OK at this time.
Go to step 5. 5. Do the tire pressure sensor location procedure to
determine the affected tire location and relate it to
the tire pressure sensor number (see page 18-53).
Go to step 6.
Check that the tire pressure sensor is properly
mounted. If necessary, replace the appropriate tire
pressure sensor (see page 18-76).
6. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4 AIR PRESSURE in the TPMS DATA LIST with the HDS,
and compare with the actual measured tire
pressure.
Go to step 7.
Replace the appropriate tire pressure sensor
(see page 18-76).
7. Turn the ignition switch to LOCK (0).
