Lateral Accelerometer Sensor Circuit Malfunction
What it means
C0186. Lateral Accelerometer Sensor Circuit Malfunction. This Chevy-enhanced code applies to Silverado, Sierra, Tahoe, Suburban, Escalade, Equinox.
Findings, check these first
- Failed lateral accelerometer inside the multi-axis acceleration sensor
- Open or shorted lateral accelerometer signal circuit to the EBCM
- Corroded connector at the multi-axis acceleration sensor under the center console
- Sensor replaced without performing the configuration and setup procedure
Standard procedure
- Read the symptom byte with a Tech2 or GDS2 to separate circuit faults from plausibility faults
- Inspect the sensor connector for corrosion and terminal tension
- Test the lateral accelerometer signal circuit for opens and shorts per GM service information
- Perform the multi-axis acceleration sensor setup procedure if the sensor was recently replaced
- Replace the sensor only after circuit tests pass, then verify StabiliTrak messages stay clear
