DTC Troubleshooting (cont’d)
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).
Go to step 7.
Check for an aftermarket electrical device
interfering with the RF signals from the sensors. If
there are no electrical devices causing interference,
replace the appropriate tire pressure sensor
(see page 18-76).
7. Turn the ignition switch to LOCK (0), and wait 5 minutes or more.
8. Test-drive the vehicle at 45 km/h (28 mph) or more for at least 1 minute.
9. Check for DTCs with the HDS.
Check for loose terminals and poor
connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit
(see page 18-75), and recheck.
The system is OK at this time. Clear the DTC
with the HDS. NOTE: Low battery voltage can cause this DTC. Make
sure the battery is fully charged and in good condition
(see page 22-67).
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0), then turn the ignition switch to ON (II) again.
4. Check for DTCs with the HDS.
Replace the TPMS control unit (see page
18-75).
The system is OK at this time.TPMS Control Unit Failure

NOTE: If DTC 85 stored at the same time as DTC 83,
troubleshoot DTC 85 first, then recheck for DTC 83.
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Test-drive the vehicle at 10 km/h (7 mph) or more.
4. Check the speedometer.
Go to step 5.
Update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then go to
step 1 and recheck. If the ECM/PCM was updated
and DTCs are not indicated, troubleshooting is
complete. If the ECM/PCM was substituted and
DTCs are not indicated, replace the original ECM/
PCM (see page 11-228).
5. Check the VEHICLE SPEED in the TPMS DATA LIST with the HDS.
The system is OK at this time.
Substitute a known-good TPMS control unit
(see page 18-75), and recheck. NOTE: Check for fuel and emission systems DTCs with
the HDS, and troubleshoot the ECM/PCM and F-CAN
communication errors first (see page 11-3).
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0), then turn the ignition switch to ON (II) again.
4. Wait about 5 seconds.
5. Check for DTCs with the HDS.
Go to step 6.
The system is OK at this time.
6. Test-drive the vehicle.
Go to step 10.
Go to step 7.
7. Turn the ignition switch to LOCK (0).
8. Disconnect the TPMS control unit 20P connector.
9. Test-drive the vehicle.
Check for loose terminals and poor
connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit
(see page 18-75), and recheck.
Turn the ignition switch to LOCK (0) and
reconnect all connectors, then check and
troubleshoot the fuel and emissions system
(see page 11-3).

4. Check for DTCs with the HDS.
Go to step 5.
Intermittent failure, the system is OK at this
time. Check for loose terminals between the
steering angle sensor 5P connector and the VSA
modulator-control unit 37P connector. Refer to
intermittent failures troubleshooting (see page
19-98).
5. Turn the ignition switch to LOCK (0).
6. Disconnect the steering angle sensor 5P connector.
7. Disconnect the VSA modulator-control unit 37P connector (see step 2 on page 19- 171).8. Check for continuity between steering angle sensor
5P connector terminal No. 3 and body ground.
Repair short to body ground in the wire
between the steering angle sensor and the VSA
modulator-control unit.

NOTE: Do not damage or drop the combination switch as the steering angle sensor is sensitive to shock and vibration.
1. With the wheels in the straight-ahead position and the steering wheel centered, remove the steering wheel (see page 17-6).
2. Remove the steering column covers (see page 17-9) and the cable reel (see page 24-200).
3. Remove the combination switch assembly (see step 11 on page 17-11).
4. Remove the combination light switch (A) and the wiper/washer switch (B) from the combination switch body assembly (C).
5. Install the combination switch body assembly in the r everse order of removal.
NOTE:  Do not remove the steering angle sensor from the combination switch body.
 When installing the cable reel, set the turn signal canceling sleeve position so that the arrow points straight up (see page 24-201).
 When installing the combination switch, tighten the m ounting screws to the specified torque and sequence
shown (see page 17-12).
