C0186 1A

^ The ignition is ON.
^ The ignition voltage is greater than 8 volts.

C0186 08
^ The ignition is ON.
^ The ignition voltage is greater than 8 volts.
^ The vehicle speed is greater than 0 km/h (0 mph).

C0186 19
^ The ignition is ON.
^ The ignition voltage is greater than 8 volts.
^ The vehicle is stopped.

C0186 52
^ The ignition is ON.
^ The ignition voltage is greater than 8 volts.
^ DTC C0196 is not set.
^ The yaw rate is less than 8 degrees per second.

Conditions for Setting the DTC
C0186 00
One of the following conditions exist:
^ The lateral accelerometer sensor input voltage is less than 0.15 volts.
^ The lateral accelerometer sensor input voltage is greater than 4.85 volts for 0.03 seconds.

C0186 08
The lateral accelerometer voltage does not increase at least 0.5 volts during the lateral accelerometer sensor self test.

C0186 09
The lateral jerk exceeds 11 g per second twice within 0.2 seconds.

C0186 19
The lateral acceleration is greater than 0.5 g for more than 1 second.

C0186 1A
Both of the following conditions exist:
^ The compensated bias value of the lateral accelerometer sensor is greater than 0.3 g.
^ The yaw rate is centered.

C0186 52
The slip rate error exceeds 0.5 g 60 times within one drive cycle.

Action Taken When the DTC Sets
^ The EBCM disables the VSES for the duration of the ignition cycle.
^ The DIC displays the Service Stabilitrak message.
^ The ABS/TCS remains functional.

Conditions for Clearing the DTC
^ The condition for the DTC is no longer present and the DTC is cleared with a scan tool.
^ The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Diagnostic Aids
The following conditions can cause this concern:
^ Improper steering alignment.
^ Open, short to ground, or short to voltage.
^ Internal lateral accelerometer failure.
^ EBCM internal failure.

Test Description
The numbers below refer to the step numbers on the diagnostic table.
2. Tests for the proper voltage output on the 5-volt reference circuit and the proper operation of the signal circuit.
3. Tests for possible low 5-volt reference output or a problem with the signal circuit.
4. Tests for a short to voltage on the 5-volt reference circuit. If a short to voltage exists, other DTC's may be set for the vehicle stability system.
8. Tests for a problem with the low reference circuit. If a short to voltage exists, other DTC's may be set for the vehicle stability system.
