CVT Pressure Test (CVT): Test

NOTE:

Check for DTCs. If any DTCs are stored, troubleshoot and clear them first.
Do not allow dust or other foreign particles to enter the inspection port.
Do not test pressure for more than 10 seconds at a time.
Do not change the transmission position/mode while raising the engine speed.
Be sure to check the transmission fluid level after each pressure test. When installing or removing the A/T oil pressure gauge, transmission fluid may run out of the inspection ports.
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.

Engine - Warm Up

1. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice)

2. Turn the engine off.

Transmission Fluid Level - Check

Forward Clutch Pressure - Test

3. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice)

4. Shift the transmission to D position/mode

5. Measure the forward clutch pressure at the engine idling while firmly pressing the brake pedal.

Pressure	Standard
Forward clutch	390-880 kPa (3.98-8.97 kgf/cm2, 56.6-127.6 psi)

6. Turn the engine off

7. If the forward clutch pressure is out of the standard, refer to the problem and probable cause (s) listed in the table.

Problem	Probable cause (s)
No or low forward clutch pressure	Transmission fluid pump defective Valve body defective CVT clutch pressure control solenoid valve defective Forward clutch defective

8. Remove the A/T oil pressure gauge

9. Install the sealing bolt with a new sealing washer to the forward clutch pressure inspection port.

Reverse Brake Pressure - Test

1. Remove the sealing bolt (A).

2. Install pressure gauge adapter C to the reverse brake pressure inspection port.

NOTE: Pressure gauge adapter C is a component of the pressure gauge adapter (070AJ-RT4A101).

3. Install the A/T oil pressure gauge set, the 2, 210 mm A/T pressure hose, and the A/T pressure adapter to pressure gauge adapter C

4. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice)

5. Shift the transmission to R position/mode

6. Measure the reverse brake pressure at engine idling while firmly pressing the brake pedal.

Pressure	Standard
Reverse brake	390-880 kPa (3.98-8.97 kgf/cm2, 56.6-127.6 psi)

7. Turn the engine off

8. If the reverse brake pressure is out of the standard, refer to the problem and probable cause (s) listed in the table.

Problem	Probable cause (s)
No or low reverse brake pressure	Transmission fluid pump defective Valve body defective CVT clutch pressure control solenoid valve defective Reverse brake defective

9. Remove the A/T oil pressure gauge

10. Install a new sealing bolt to the reverse brake pressure inspection port.

Drive Pulley Pressure - Test

3. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice)

4. Shift the transmission to N position/mode

5. Measure the drive pulley pressure at engine idling while firmly pressing the brake pedal.

Pressure	Standard
Drive pulley	590-1, 140 kPa (6.02-11.62 kgf/cm2, 85.6-165.3 psi)

6. Turn the engine off

7. If the drive pulley pressure is out of the standard, refer to the problem and probable cause (s) listed in the table.

Problem	Probable cause (s)
No or low drive pulley pressure	Transmission fluid pump defective Valve body defective CVT drive pulley pressure control solenoid valve defective
Drive pulley pressure too high	Valve body defective CVT drive pulley pressure control solenoid valve defective

8. Remove the A/T oil pressure gauge

9. Install the sealing bolt with a new sealing washer to the drive pulley pressure inspection port.

Driven Pulley Pressure - Test

NOTE:

Driven pulley pressure may be above 3, 260 kPa (33.24 kgf/cm² , 472.8 psi) when there is a transmission problem that causes the PCM to go into fail-safe mode.
When troubleshooting, you must use the A/T high pressure gauge to measure driven pulley pressure.

1. Remove the sealing bolt (A) with the sealing washer (B).

2. Install the A/T high pressure gauge and the A/T pressure adapter to the driven pulley pressure inspection port.

3. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice)

4. Shift the transmission to N position/mode

5. Measure the driven pulley pressure at engine idling while firmly pressing the brake pedal.

Pressure	Standard
Driven pulley	850-1, 400 kPa (8.67- 14.28 kgf/cm2, 123.3-203.1 psi)

6. Turn the engine off

7. If the driven pulley pressure is out of the standard, refer to the problem and probable cause (s) listed in the table.

Problem	Probable cause (s)
No or low driven pulley pressure	Transmission fluid pump defective Valve body defective CVT driven pulley pressure control solenoid valve defective
