Toyota 4Runner: Diagnostic Trouble Code Chart
DIAGNOSTIC TROUBLE CODE CHART
NOTICE:
Turn the ignition switch off before removing parts.
HINT:
- If no abnormality is found when inspecting parts, inspect the stabilizer control ECU and ground points for poor contact.
- If a trouble code is output during the DTC check, check the circuit indicated by the DTC. For details of each code, refer to the "See page" for the respective "DTC Code" in the DTC chart.
- When 2 or more DTCs are output, perform circuit inspections one by one until the problem is identified.
- Inspect the fuse and relay before investigating the trouble areas as shown in the table below.
