Description of ESC Electronic Stability Control (ESC) recognizes critical driving conditions, such as panic reactions in dangerous situations, and stabilizes the vehicle by wheel-individual braking and engine control intervention.
Diagnosis With GDS 1. BSD system defects can be quickly diagnosed with the GDS. GDS operates actuator quickly to monitor, input/output value and self diagnosis. 2. Connect the cable of GDS to the data link connector in driver side crash pad lower panel, turn the power on GDS.
Inspection 1. Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals. 2. Inspect the voltage value whether it is sufficient to be regular value or not. Voltage = 0.00878835 * Pressure + 0.37081095 [PSIA] 3.
