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 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.
Test the CVT pressure under the following conditions:

?
Engine warmed up
?
While idling at 600 ± 50 rpm
?
Without load

8. CVT Driven Pulley Pressure - Test

NOTE:
CVT Driven pulley pressure may be above 3,430 kPa (34.98 kgf/cm2, 497.5 psi) when there is a transmission problem that causes the PCM to go into fail-safe operation.
When troubleshooting, you must use the A/T high pressure gauge to measure CVT driven pulley pressure.

1.
