VEHICLE STABILITY CONTROL SYSTEM DIAGNOSTIC TROUBLE CODE CHART

Note

Turn the ignition switch off before removing any parts.

Tech Tips

If no malfunction is found when inspecting parts, inspect the skid control ECU and ground points for poor connections.
If a trouble code is displayed during the DTC check, inspect the trouble areas listed for that code. For details, refer to the "See page" reference for the DTC.
When 2 or more DTCs are detected, perform diagnosis for each DTC, one by one until the problem is identified.
If DTCs were checked using the warning light or indicator light, refer to the tables in DTC Check/Clear to cross-reference them to the 5-digit DTCs shown in the following tables.
Inspect the fuses and relays before inspecting the trouble areas shown in the following table.
