Conditions for Setting the DTC: C1284
WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The EBCM performs 7 different tests to detect a DTC condition. The numbers below correspond to the numbers in Conditions for Running the DTC.
- The compensated bias value of the lateral accelerometer sensor is greater than 0.3 g.
- The lateral accelerometer sensor performs a self test that results in an offset of 0.5 g. The EBCM compares the sensor output during the self test with the output following the test. The DTC sets when the lateral acceleration immediately following the self test is greater than the self test output minus 0.4 g.
- The lateral jerk is greater than 16.5 g/second for 0.12 seconds more than 2 times within the ignition cycle.
- The lateral acceleration is 0.4 g for 0.25 seconds.
- The side slip error is greater than 0.5 g 30 times within a drive cycle.
- The side slip error is greater than 0.5 g for 5 seconds. Under this condition, this DTC will set along with DTC C1281.
- The oversteer term is negative for 2 seconds. The oversteer term is the yaw rate value times the lateral acceleration value. Under this condition, this DTC will set along with DTC C1281.
