DTC C104B-94: Rear Axle Rod Pressure Regulating Valve - Unexpected operation: Action

Refer to the appropriate system wiring diagram and check the dynamic response rear actuator rod-side pressure regulating valve coil circuit, harness and connectors for short circuit faults. Repair circuit as required, Clear the DTCs and retest
Refer to the appropriate system wiring diagram and check the resistance of the dynamic response rear actuator rod-side pressure regulating valve coil circuit (nominal value should be 5.1 ohms). Repair circuit as required, Clear the DTCs and retest
Check for air and/or other contaminants in dynamic response hydraulic fluid circuit and bleed as required
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
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
If the fault persists, check the dynamic response control module for 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 reset adaptive data. Clear the DTCs and retest
If the fault persists, install a new dynamic response hydraulic pump. Clear the DTCs and retest
If the fault persists, check the condition and integrity of the dynamic response hydraulic return line and repair or replace as required. Clear the DTCs and retest
