Causes

Open or short in sensor signal wire
Corroded or loose connector at sensor
Failed lateral accelerometer sensor
Damaged harness (chafing, water ingress)
Poor ground or reference supply to sensor
Intermittent connection due to vibration or damaged pins

Symptoms

ABS, ESC or traction control warning lamp illuminated
Stability control or ABS functionality reduced or disabled
Diagnostic trouble code C1460 stored in control module
Erratic stability control interventions during cornering or lane changes
Possible degraded steering/braking feel when systems intervene

What to check

Read and record freeze–frame and stored codes with a scan tool; clear code and attempt to reproduce
Visually inspect lateral accelerometer, bracket and nearby wiring for damage, corrosion or water entry
Check connector seats and pin condition at the sensor and module; unplug and inspect contacts
Perform a wiggle test on harness while monitoring live data for intermittent changes
Verify vehicle battery voltage and ground quality at sensor ground point
Check for related codes (ABS, yaw rate, steering angle, CAN bus) that could indicate communication or upstream faults

Signal parameters

Typical sensor supply/reference: ~5.0 V (vehicle-specific — confirm with service data)
Signal output at 0 g (stationary, flat): approximately mid-supply (≈2.5 V) — vehicle-dependent
Signal range: sensor outputs vary with lateral acceleration; expect a proportional change from mid-supply for left/right lateral g (typical ±1–3 g operating range)
At rest: lateral G ~0.0 g; small steady offset may be present — compare to known-good data or service limits

Diagnostic algorithm

Connect a manufacturer-level scan tool; record live lateral acceleration and related sensors (yaw rate, longitudinal accel, wheel speeds, steering angle).
Clear codes, key on engine off (KOEO) and observe live data: at rest lateral accel should be ~0 g and signal voltage ~mid-supply. If erratic or out of range, proceed.
Visually inspect sensor, mounting and harness for damage, corrosion, water ingress or loose fasteners.
With ignition ON, backprobe sensor connector: verify reference supply voltage and ground; measure signal voltage at connector and compare to expected mid-supply. Refer to vehicle service data for exact values.
Perform wiggle test of harness and connector while watching live data for intermittent faults. Check for shorts to power/ground if signal pins move to rail voltages.
If supply and ground are correct but signal is invalid, unplug sensor and check harness continuity to control module pins; repair any opens/shorts.
If wiring checks good, substitute a known-good lateral accelerometer (or swap compatible sensor if available) and retest. If fault follows sensor, replace sensor.
If sensor replacement does not clear the issue, inspect/scan ABS/ESC module for internal faults and communication errors; consider module reprogram/calibration per service information.
After repair, clear codes and perform required sensor/vehicle calibrations and a road test to confirm system operation.

Likely causes

Connector corrosion or bent pins at lateral accelerometer
Open or shorted signal wire between sensor and ABS/ESC module
Failed accelerometer (internal electronics)
Poor ground or battery/ignition reference at sensor connector
Sensor mounting loose or impacted causing internal damage
