DTC C1119-09: Hydraulic Pressure - Component Failures: Action
- Check and top up the hydraulic fluid as required
- Check integrity of the hydraulic system. Apply external pressure to the high pressure fluid flexible lines between the pump and valve block and check for leaks. Check the formed hydraulic pipes and connections for leaks. Rectify any leaks as required. Clear the DTCs and retest
- If the fault persists, install a new dynamic response valve block as required and clear adaptive data. Clear the DTCs and retest
- If the fault persists, check the operation of the front and rear actuators and install new actuator(s) as required. Clear the DTCs and retest
- If the fault persists, check the dynamic response hydraulic pump pressure/fluid flow. If faulty, install a new dynamic response hydraulic pump as required
