C1915 — Ride Control LF Shock Actuator Circuit Short To Battery

About C1915

C1915 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.

When C1915 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

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.

C1915 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 suspension ride control module controls the electronically adjustable shock absorbers on vehicles fitted with adaptive damping. Each shock contains an electrically operated actuator solenoid that the module drives to vary damping force. DTC C1915 is set when the module detects that the left front (LF) shock actuator control circuit is shorted to battery voltage, meaning unexpected high voltage is present on the control wire. This is typically caused by a chafed wire touching a power feed, a short inside the actuator, or a connector fault that bridges the control circuit to a voltage source...
