Frequently searched by part numbers 1488926077 and 6554G5, this unit is a direct-fit replacement for vehicles that use the same switch assembly and connector layout.
Key Benefits
Reliable restoration of ESP on/off control, maintenance-friendly replacement for workshop and DIY repairs, and improved driver confidence when the original switch has failed or become intermittent. Ideal for mechanics and experienced home repairers who search by OEM part number.
How The Part Works
The switch provides a user interface to the vehicle’s ESP/ASR system, sending a signal to the ABS/ESP control module to toggle traction and stability control functions. The component typically contains a microswitch and contact terminals that communicate with the vehicle wiring harness. It does not itself control braking or engine torque but acts as the command input to the main ESP module.
How To Replace
- Safety First: Disconnect the vehicle battery before starting to avoid short circuits and to protect vehicle electronics.
- Remove Trim: Carefully pry out the surrounding dash trim or switch cluster bezel using appropriate trim tools to avoid damage.
- Extract Switch: Unscrew or unclip the old switch from its housing and disconnect the electrical connector.
- Install New Switch: Plug in the replacement switch, secure it in the mounting bracket, and refit the trim.
- Reconnect Battery And Test: Reconnect the battery and verify correct function of the ESP indicator and On/Off operation while the ignition is on.
