About C1310

C1310 is a manufacturer-specific chassis diagnostic trouble code recorded for Lexus vehicles. 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.

C1310 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

The Brake Control ECU continuously monitors communication messages from the Hybrid Vehicle Control ECU (or EV Control ECU) via the CAN network. DTC C1310 is set when the Brake Control ECU receives a malfunction signal indicating an HV/EV system fault, or when required hybrid system status information is not received within the specified time. This code does not indicate a brake system failure itself, but rather that the brake ECU has been informed of a hybrid or electric system malfunction that may affect regenerative braking or vehicle control strategies.
