VEHICLE STABILITY CONTROL SYSTEM (for Hatchback) > DIAGNOSTIC TROUBLE CODE CHART


NOTICE:
Turn the ignition switch off before removing parts.

HINT:
  1. If no abnormality is found when inspecting parts, inspect the skid control ECU and ground points for poor contact.
  2. 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.
  3. When 2 or more DTCs are detected, perform circuit inspection one by one until the problem is identified.
  4. For DTCs output by the warning light or indicator light, refer to the DTC charts in DTC Check/Clear.
  5. Inspect the fuse and relay before investigating the trouble areas as shown in the table below.
