NOTE:
How to read the torque specifications.
Check for DTCs. If any DTCs are stored, troubleshoot and clear them first.
Do not allow dust or other foreign particles to enter the port while installing the A/T oil pressure gauge.
Be sure to check the transmission fluid level after each pressure port test. When installing or removing the A/T oil pressure gauge, transmission fluid may run out of the pressure inspection ports.
Do not test pressure for more than 10 seconds at a time.
Do not move the shift lever while raising the engine speed.
Disable the VSA by pressing the VSA OFF button.
VSA DTC(s) may come on during the test-drive. If the VSA DTC(s) come on, clear the DTC(s) after testing is done with the HDS.

1. A/T Oil Pressure Gauge - Set
1.
When testing the oil pressure at each inspection port, select a suitable adapter from the following table, and connect each adapter to the A/T oil pressure gauge.
Inspection port
Tool
Forward clutch pressure
Pressure gauge adapter B
CVT drive pulley pressure
Pressure gauge adapter B
CVT driven pulley pressure
Pressure gauge adapter A
Pressure gauge adapter E
Reverse brake pressure
Pressure gauge adapter B

7. Forward Clutch Pressure - Test
1.
Assemble the pressure gauge; install the 2,210 mm A/T pressure hose, the A/T pressure adapter, and pressure gauge adapter B to the A/T oil pressure gauge set.
2.
Remove the sealing bolt (A) with the sealing washer (B).
3.
Install the pressure gauge to the forward clutch pressure inspection port.
4.
Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice).
5.
Shift the transmission to D position/mode.
6.
Measure the forward clutch pressure at the engine idling while firmly pressing the brake pedal.
Pressure
Standard
Forward clutch
450?730 kPa (4.59?7.44 kgf/cm2, 65.3?105.9 psi)
7.
Turn the engine off.
8.
If the forward clutch pressure is out of the standard, refer to the problem and probable causes listed in the table.
Problem
Probable causes
No or low forward clutch pressure
Transmission fluid pump defective
CVT clutch pressure control solenoid valve defective
Forward clutch defective
Valve body assembly defective
Manual valve body defective
9.
Remove the pressure gauge.
10.
Install the sealing bolt with a new sealing washer to the forward clutch pressure inspection port.
NOTE: Do not reuse the old sealing washer.

8. CVT Drive Pulley Pressure - Test
1.
Assemble the pressure gauge; install the 2,210 mm A/T pressure hose, the A/T pressure adapter, and pressure gauge adapter B to the A/T oil pressure gauge set.
2.
Remove the sealing bolt (A) with the sealing washer (B).
3.
Install the pressure gauge to the CVT drive pulley pressure inspection port.
4.
Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice).
5.
Shift the transmission to N position/mode.
6.
Measure the CVT drive pulley pressure at engine idling while firmly pressing the brake pedal.
Pressure
Standard
CVT drive pulley
260?540 kPa (2.65?5.51 kgf/cm2, 37.7?78.3 psi)
7.
Turn the engine off.
8.
If the CVT drive pulley pressure is out of the standard, refer to the problems and probable causes listed in the table.
Problems
Probable causes
No or low CVT drive pulley pressure
Transmission fluid pump defective
CVT drive pulley pressure control solenoid valve defective
Valve body assembly defective
CVT drive pulley pressure too high
CVT drive pulley pressure control solenoid valve defective
Valve body assembly defective
9.
Remove the pressure gauge.
10.
Install the sealing bolt with a new sealing washer to the CVT drive pulley pressure inspection port.
NOTE: Do not reuse the old sealing washer.

9. CVT Driven Pulley Pressure - Test
NOTE:
CVT driven pulley pressure may be above 3,740 kPa (38.14 kgf/cm2, 542.4 psi) when there is a transmission problem that causes the TCM to go into fail-safe operation.
When troubleshooting, you must use the A/T high pressure gauge to measure the CVT driven pulley pressure.
3.
Temporarily install the CVT driven pulley pressure sensor with the sealing washer (B) to pressure gauge adapter A.
4.
Assemble the pressure gauge; install the A/T high pressure gauge and the A/T pressure adapter to pressure gauge adapter A.
5.
Install pressure gauge adapter E (quick connector) to the CVT driven pulley pressure inspection port.
6.
Install the pressure gauge to pressure gauge adapter E (quick connector).

7.
Connect the connector (A) to the CVT driven pulley pressure sensor (B).
8.
Temporarily install the air cleaner.
9.
Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice).
10.
Shift the transmission to N position/mode.
11.
Measure the CVT driven pulley pressure at engine idling while firmly pressing the brake pedal.
Pressure
Standard
CVT driven pulley
490?900 kPa (5.00?9.18 kgf/cm2, 71.1?130.5 psi)
12.
