C2005-77 Right Actuator - Commanded position not reachable: Action

NOTE: This DTC will set after detecting disc contact, but full clamping force is not reached within three seconds of the brake being applied. Or, if the target disc clamping force is not achieved within 25 seconds from start of park brake application

Refer to the relevant section of the workshop manual and test the battery and charging system
Check that the electric park brake right actuator is correctly installed. If the actuator is correctly installed, release and apply the electric parking brake several times
Refer to the electrical circuit diagrams and check the electric park brake right actuator circuit for open circuit, high resistance
Using the Jaguar Land Rover Approved Diagnostic Equipment, check datalogger signal - Right Park Brake Motor Current (0x2B34) - and operate the electric park brake switch. If the signal is <15A refer to the electrical circuit diagrams and check the electric park brake control module ground circuits for open circuit, high resistance
If the fault persists, install a new electric park brake right actuator as required
