NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
 This DTC is indicated when a ECM/PCM update is not completed.
 Do not turn the ignition switch to LOCK (0) or ACC (I) while updating the ECM/PCM. If you do, the ECM/
PCM can be damaged.
1. Do the ECM/PCM update procedure (see page 11-227).
2. Check for Temporary DTCs or DTCs with the HDS.
Replace the original ECM/PCM (see page
11-228).
The update is complete. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting. NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
 Information marked with an asterisk ( ) applies to the ’06-08 models.
 Information marked with a double asterisk ( ) applies to the ’09 model.
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Check for Temporary DTCs or DTCs with the HDS.
Go to step 4.
Intermittent failure, the system is OK at this
time.
4. 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).
5. Check for Temporary DTCs or DTCs with the HDS.
If the ECM/PCM was updated, substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the ECM/PCM was substituted, go to
step 1.
If the ECM/PCM was updated, troubleshooting
is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-228). If
any other Temporary DTCs or DTCs are indicated,
go to the indicated DTC’s troubleshooting.

Axle disengaged Check the ATF level, and check the ATF cooler lines
for leaks and loose connections. If necessary, clean
the ATF cooler lines.
Check for a loose shift cable at the shift lever and
the selector control lever.
Improper alignment of ATF pump and torque
converter housing may cause ATF pump seizure.
The symptoms are mostly an rpm-related ticking
noise or a high pitched squeak.
Check the line pressure.
Be careful not to damage the torque converter
housing when replacing the main ball bearing. You
may also damage the ATF pump when you torque
down the main valve body. This will result in ATF
pump seizure if not detected. Use the proper tools.
Install the main seal flush with the torque converter
housing. If you push it into the torque converter
housing until it bottoms out, it will block the fluid
return passage and result in damage.
Check the ATF strainer for debris. If the ATF
strainer is clogged with particles of steel or
aluminum, inspect the ATF pump. If the ATF pump
is OK, find the damaged components that caused
the debris. If no cause for contamination is found,
replace the torque converter.
Inspect the differential pinion gears for wear. If the
differential pinion gears are worn, replace the
differential assembly, replace the ATF strainer,
thoroughly clean the transmission, and clean the
torque converter, cooler, and lines.

Inspect the clutch piston, the clutch piston check
valve, and the O-rings. Check the spring retainer
and the retainer seal for wear and damage. Inspect
the clearance between the clutch end-plate and the
top disc. If the clearance is out of tolerance, inspect
the clutch discs and the plates for wear and
damage. If the discs are worn or damaged, replace
them as a set. Inspect the clutch wave-plate height.
If the height is out of tolerance, replace the wave-
plate. If the discs and the plates are OK, adjust the
clearance with the clutch end-plate.
Inspect the 1st clutch feed pipe. If the 1st clutch
feed pipe is scored, replace the end cover.
Replace the secondary shaft if the bushing for the
1st clutch feed pipe is loose or damaged.
Check the 1st accumulator piston, the O-ring, and
the springs in the regulator valve body for wear
and damage.

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).

10. Turn the ignition switch to LOCK (0).
11. Short the SCS line with the HDS.
12. Disconnect ECM/PCM connector A (44P).
13. Disconnect the TPMS control unit 20P connector.
14. Check for continuity between the TPMS control unit
20P connector terminals and the ECM/PCM
connector A (44P) terminals according to the table.

Check for loose terminals and poor
connections at the TPMS control unit and G 504. If
necessary, substitute a known-good TPMS control
unit (see page 18-75), and recheck.
Repair open in the wire between the TPMS
control unit and the ECM/PCM. 1. Turn the ignition switch to ON (II).
2. Check for DTCs with the HDS.
3. Note the tire pressure sensor(s) number by the
indicated DTC.
91 No. 1
93 No. 2
95 No. 3
97 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. Clear the DTC with the HDS.
6. Test-drive the vehicle at 45 km/h (28 mph) or more for at least 1 minute.
7. Check for DTCs with the HDS.
Replace the appropriate tire pressure sensor
(see page 18-76) and recheck. If DTCs are still
present, substitute a known-good TPMS control
unit (see page 18-75), and recheck.
If any other DTCs are indicated, troubleshoot
the appropriate DTC. If no DTCs are indicated, the
system is OK at this time.Tire Pressure Sensor
