Vehicle Accelerometer Power Circuit Failure

What Does C1460 Mean?

This code indicates a failure in the power supply circuit for the vehicle accelerometer package. The accelerometer sensors require a regulated power supply (typically 5V or 8V) from the chassis control module. When this supply circuit fails, all accelerometers fed by this power rail lose functionality simultaneously. This is a higher-level fault than individual sensor failures and often disables multiple chassis control features at once.

Safety Warning

A failed accelerometer power supply disables all acceleration sensing simultaneously, causing complete loss of electronic stability control and degraded ABS performance. The vehicle has no inertial reference for detecting skids, slides, or rollover conditions.

Common Causes

35%

Open circuit in the accelerometer power supply wire between the ABS/ESC module and the sensor cluster

Power Supply Harness
Sensor Power Distribution Connector

25%

ABS/ESC module internal voltage regulator failure on the sensor power supply output

ABS/ESC Module
Internal Voltage Regulator IC

25%

Short to ground on the accelerometer power supply wire causing the module's internal protection to shut down the supply rail

Power Supply Wire
Sensor Connectors
Harness Grommets

15%

Excessive current draw from a shorted accelerometer sensor overloading the power supply circuit

Accelerometer Sensor
Sensor Internal Short

Diagnostic Steps

1

Step 1: Check whether multiple accelerometer or chassis sensor codes are set simultaneously. If C1454, C1455, C1462, and C1463 are all present along with C1460, a shared power supply failure is confirmed rather than multiple individual sensor failures.

Step 2: Measure the accelerometer power supply voltage at any accelerometer sensor connector. The power pin should show a stable regulated voltage (typically 5V or 8V depending on the vehicle). If the voltage is missing or significantly low, the supply circuit is faulted.

3

Step 3: Disconnect all accelerometer sensors from the power supply rail and measure the voltage at the module output. If voltage returns when the sensors are disconnected, one of the sensors has an internal short loading down the supply. Reconnect sensors one at a time to identify the shorted unit.

Step 4: If the supply voltage remains absent with all sensors disconnected, check the power wire continuity from the module to the first sensor connection point. Also verify the module's power and ground connections are solid (battery voltage on power pins, less than 0.1V drop on grounds).

5

Step 5: If wiring is intact and no external loads are present, the module's internal voltage regulator has failed. Module replacement is required. After replacement, perform a full chassis control system initialization and calibration.

What causes C1460?

The most common cause of C1460 (Vehicle Accelerometer Power Circuit Failure) is: Open circuit in the accelerometer power supply wire between the ABS/ESC module and the sensor cluster

How much does it cost to fix C1460?

Typical repair costs for C1460 range from $150 to $1,000, depending on the vehicle, location, and whether you do it yourself or go to a shop.

Is it safe to drive with C1460?

A failed accelerometer power supply disables all acceleration sensing simultaneously, causing complete loss of electronic stability control and degraded ABS performance. The vehicle has no inertial reference for detecting skids, slides, or rollover conditions.

How do I diagnose C1460?

Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1460 to identify the root cause.
