Hydraulic Pressure Check

Lift up the vehicle.
CAUTION: To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958.
Connect scan tool MB991958 to the data link connector.

Disconnect the hydraulic unit and transfer connector assembly, and connect the special tools (3.0 MPa (427 psi) oil pressure gauge [MD998330] and adapter [MB991705]) to the hydraulic unit.
Turn the ignition switch to the "ON" position.
Perform the scan tool MB991958 actuator test (Item No.05), and forcibly drive the hydraulic unit.

NOTE:
- The actuator test (Item No.05 ACD Operation Check Mode) is performed for 1 minute, after which it will be cleared automatically. Drive can also be cleared during forced driving using the clear key of the scan tool MB991958.
- If the hydraulic unit function has been stopped by fail-safe, the hydraulic unit cannot be forcibly driven.
CAUTION: While the oil pressure is checked, add fluid as necessary to ensure that it is left in the oil reservoir during the entire procedure.
Check that the generated oil pressure of the hydraulic unit satisfies the standard value.
1. Standard value: 1.0 - 1.6 MPa (145 - 232 psi)
If the measured value exceeds the standard value, replace the hydraulic unit.
Connect the hydraulic unit and transfer connector assembly, and tighten the flare nut at the specified torque.
1. Tightening torque:
  1. 34 +/- 5 N.m (25 +/- 4 ft-lb) (when screw is dry)
  2. 26 +/- 4 N.m (19 +/- 3 ft-lb) (when screw is applied with oil)
Supply the specified fluid up to the MAX level of the oil reservoir, and bleed the oil pressure pipes.
1. Specified fluid: DIAMOND ATF SP III
