C1458 — Accelerometer Front Circuit Short To Battery

About C1458

C1458 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 C1458 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.

C1458 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 C1458 fault code indicates the suspension control module has detected a short to battery voltage on the front accelerometer signal circuit. The front accelerometer reports vertical body acceleration at the front of the vehicle, providing the module with motion data used to calculate adaptive damping. The sensor outputs a 0V to 5V analog signal centred on approximately 2.5V (zero G). This code is specifically set when the module detects the signal pinned at battery voltage or above the 5V reference, indicating the signal wire is shorted directly to a battery feed. When this code is active, ...
