The electronic suspension control (ESC) module performs checks of internal calibration data. if a fault condition is detected, the ESC module will set the fault DTC and may, depending upon the fault type, illuminate the LED in the ESC switch. Recovery from any controller fault condition is attempted only after the ignition is cycled ON and OFF
Ignition ON.
• | The DTC is set when any calibration faults internal to the ESC module are detected. |
• | The fault is detected during 3 consecutive ignition cycles or during the same ignition cycle after clearing the DTC with the scan tool. |
• | The ESC module illuminates the LED in the ESC switch. |
• | The ESC module disables all ESC functionality. |
• | A history DTC will clear when the ESC no longer senses the malfunction and the ignition is cycled ON and OFF. |
• | Using a TECH2 Scan Tool Unit. |
