C1755 — Power Limit Shutdown Fault

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Generic

About C1755

C1755 is a manufacturer-specific chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1755 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

DTC C1755 indicates that a chassis system control module has triggered a power limit shutdown to protect itself or its actuators from electrical overload. Control modules that drive high current devices, such as hydraulic pump motors and actuator solenoids, monitor the current draw and temperature of their output stages, and when consumption exceeds the design limit the module shuts the output down and sets this code. The fault is commonly triggered by a binding or worn pump motor or actuator drawing excessive current, repeated high duty operation causing the output driver to overheat, or supp...
