NOTE: Turn the ignition switch off before removing parts.

HINT:

  • If no malfunction is found when inspecting parts, inspect the skid control ECU and ground points for poor contact.
  • If a trouble code is displayed during the DTC check, check the circuit indicated by the DTC. For details of each code, refer to the page for the respective DTC Code in the DTC chart.
  • When 2 or more DTCs are detected, perform circuit inspection one by one until the problem is identified.
  • Inspect the fuses and relays before investigating the trouble areas as shown in the table below.

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.
