About C1164

C1164 is a manufacturer-specific chassis diagnostic trouble code recorded for Toyota 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.

C1164 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 Skid Control ECU sets this DTC when it detects an electrical malfunction in the Cut Valve 1 circuit, which is part of the ABS hydraulic control unit (the brake actuator assembly). The cut valves modulate hydraulic pressure to individual brake circuits during ABS, TRAC, and VSC operation. The ECU continuously monitors circuit continuity, supply voltage, and solenoid current flow. When the Cut Valve 1 circuit shows abnormal characteristics such as an open circuit, a short, or an out of range current draw, the code is stored. The driver typically sees the ABS, brake, VSC, and TRAC warning lig...
