DTC C1116-62: Torque/Pressure - Signal compare failure: Action

Check for air and/or other contaminants in dynamic response hydraulic fluid circuit and bleed as required
Check dynamic response hydraulic fluid levels. Check the dynamic response reservoir and hydraulic circuits for leaks. Repair or replace leaking components as required. Clear the DTCs and retest
Drain reservoir and inspect mesh filter for signs of significant contamination. Identify source of contamination (check condition and operation of dynamic response actuators and hydraulic pump) and rectify as required. Flush dynamic response hydraulic fluid circuit and recharge with clean hydraulic fluid
If the fault persists, check the dynamic response control module for front/rear dynamic response actuator pressure sensor fault DTCs and refer to the relevant DTC index. 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 dynamic response hydraulic pump pressure/fluid flow. If faulty, check and install a new dynamic response hydraulic pump as required
Using JLR approved diagnostic equipment, demand 55 bar pressure from the pressure control valve for 5 minutes to heat the system. Then, demand 50 bar from the front axle rod pressure regulating valve for 2 minutes, if pressure drops and/or the pipes to the front actuator get hot, this indicates a faulty actuator. Check and install a new roll bar module as required. Clear the DTCs and retest
Repeat this procedure for the front axle piston/rear axle rod/rear axle piston pressure regulating valves
