Self-Diagnosis Function

ESP® hydraulic unit/control module assembly monitors each input and output signals. When ESP® hydraulic unit/control module assembly detects any malfunction, ABS warning light (1), EBD warning light (brake warning light) (2), ESP® warning light (3), and/or ESP® OFF light (4) are turned ON to indicate the abnormality to driver.

• When ignition mode of the keyless push start system is changed to "ON", ABS warning light, EBD warning light (brake warning light), ESP® warning light and ESP® OFF light turn ON for 2 seconds to check its circuit.
• When no abnormality is detected (the system is in good condition), these lights turn OFF after 2 seconds. However, when parking brake is operated, EBD warning light (brake warning light) remains ON.
• When an abnormality in the system is detected, ABS warning light, EBD warning light (brake warning light), ESP® warning light and/or ESP® OFF light are turned ON and DTC is stored in ESP® hydraulic unit/control module assembly.
