DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
ESP® Control Module
The parameter data below are values measured with the SUZUKI scan tool when the normally operating vehicle is under the following conditions. When taking measurements for comparison by using the SUZUKI scan tool, be sure to check that the vehicle is under the following conditions:
- Parking brake is applied and wheels are blocked.
- Ignition switch is at ON position.
- Air conditioner is turned OFF (if equipped).
- No load is applied to power steering (if equipped). (Do not turn it)
- Set the wheel in straight-ahead position and hands off steering wheel.
- All electric loads are turned OFF (except ignition).
- No DTC is detected.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
