The power steering system adopts the electric power steering assisting for the control force of the steering wheel in
the driving force of the electric motor.
The EPS control unit is doing an appropriate steering force control according to the running situation of the vehicle (at
time of low speed, lightness, by the control of emphasis and high-speed running time, control with the steady weight
and the control which will be switched from low speed to high speed smoothly later) by the EPS motor.
The EPS control unit is designed for use with an automotive power steering for the primary purpose of controlling the
assist motor (brushless motor) for the power steering by using as inputs the steering torque signals received from the
‘‘steering torque sensor’’ installed in the steering gearbox as well as the speed signals received from the ‘‘vehicle
speed sensor’’ installed in the vehicle. In addition to the above function, the EPS control unit also provides the failsafe
function, self diagnosis function and motor output limiting function.

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.

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.
