Suzuki Grand Vitara dashboard issues with ESP off switch functioning only in 4HL on Suzuki Grand Vitara

Some Suzuki Grand Vitara owners report experiencing dashboard issues related to the ESP off switch functioning only in 4HL, which can lead to the ESP systems being disabled while the ABS remains operational. Owners have noted that if the ESP lights on the dashboard are permanently illuminated, it may indicate a faulty ESP system, prompting the need to access the ESP Electronic Control Unit (ECU) memory for Diagnostic Trouble Codes (DTC). Furthermore, continuous illumination of the "ESP" light, particularly when driving on icy roads, suggests that the ESP system may not be functioning, despite the ABS brakes still operating correctly. To resolve these issues, it is recommended to reset the ESP system by erasing all faults stored in the ECU and checking or replacing the brake pedal switch if necessary. Additionally, some owners have encountered warnings regarding the use of non-specified tires or wheels, which can adversely affect the ESP system's performance. Addressing these concerns is crucial for maintaining optimal performance and safety in Suzuki Grand Vitara vehicles.
