NOTE: This problem occurs when the temperature
around the sensor is 40 °C ( 40 °F) or less. Note that
the diagnosis must be made in a place where ambient
temperature is 40 °C ( 40 °F) or more.
1. Test-drive the vehicle at 45 km/h (28 mph) or more for at least 1 minute.
The system is OK at this time. Clear the DTC
with the HDS.
Go to step 2.
2. Check for DTCs with the HDS.
3. Note the tire pressure sensor(s) number by the indicated DTC.

33 No. 2
35 No. 3
37 No. 4 4. 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 5.
Check that the tire pressure sensor is properly
mounted. If necessary, replace the appropriate tire
pressure sensor (see page 18-76).
5. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4 PRESSURE SENSOR TRANSMITTER BATTERY in
the TPMS DATA LIST with the HDS.
Replace the appropriate tire pressure sensor

Brake Fluid Replacement/Air BleedingHow to Troubleshoot DTCs
Intermittent Failures

ABS Components
General Troubleshooting Information (cont’d)
 The memory holds all DTCs. However, when the
same DTC is detected more than once, the more
recent DTC is written over the earlier one. Therefore,
when the same problem is detected repeatedly, it is
memorized as a single DTC.
 The DTCs are indicated in the order they occur.
 The DTCs are memorized in the EEPROM. Therefore, the memorized DTCs cannot be erased by
disconnecting the battery. Do the specified
procedures to clear the DTCs.
 Self-diagnosis can be classified into two categories: – Initial diagnosis: Done right after the ignition switch is turned to ON (II) and until the ABS indicator goes
off.
– Regular diagnosis: Done right after the initial diagnosis until the ignition switch is turned to
LOCK (0).
 When the system detects a problem, the ABS modulator-control unit shifts to fail-safe mode.
The pump motor operates when the ABS modulator-
control unit is functioning, and the fluid in the reservoir
is forced out to the master cylinder, causing kickback at
the brake pedal.  The pump motor operates when the ABS modulator- control unit is functioning.
 The ABS modulator-control unit checks the pump motor operation one time after completing initial
diagnosis during regular diagnosis when the vehicle
is driven over 15 km/h (10 mph).
Brake fluid replacement and air bleeding procedures
are identical to the procedures used on vehicles without
ABS (see page 19-9). The troubleshooting procedures assume that the cause
of the problem is still present, and the ABS indicator is
still on. Following a troubleshooting procedure for a
code that has been cleared but does not reset can result
in incorrect diagnosis.
1. Question the client about the conditions when the problem occurred, and try to reproduce the same
conditions for troubleshooting. Find out when the
ABS indicator came on, such as during activation,
after activation, when the vehicle was traveling at a
certainspeed,etc.Ifnecessary,havetheclient
demonstrate the concern.
2. When the ABS indicator does not come on during the test-drive, check for loose connectors, poor
contact of the terminals, etc. in the circuit indicated
by the DTC before you start troubleshooting.
3. After troubleshooting, or the repairs are done, clear the DTCs, and test-drive the vehicle under the same
conditions that originally set the DTCs. Make sure
the ABS indicator does not come on.
4. Check for DTCs from other systems which are connected via F-CAN. If there are DTCs that are
related to F-CAN, one possible cause was that the
ignition switch was turned to ON (II) with the ABS
modulator-control unit connector disconnected.
Clear the DTCs. Check for fuel and emissions DTC’s
first.
NOTE: Always troubleshoot fuel and emissions
DTC’s first.
The term ‘‘intermittent failure’’ means a system may
have had a failure, but it checks OK now. If you cannot
reproduce the condition, check for loose connectors or
terminal pins related to the circuit that you are
troubleshooting.
