Hint:
- Use these procedures to troubleshoot the vehicle stability control system.
- *: Use the intelligent tester.
- Vehicle brought to workshop
- Inspect battery voltage
Standard voltage: 11 to 14 v
If the voltage is below 11 v, recharge or replace the battery before proceeding.
- Check and clear dtc*
- Problem symptom confirmation
Result 
- Symptom simulation
- Check communication function of controller area network (can)*
- Use the intelligent tester to check for normal functioning of the can communication system.
- Perform bus check (communication malfunction dtc).
Result

Vehicle speed signal error (test mode dtc)
Description
The tire pressure warning ecu receives a speed signal from the combination
meter. This dtc is stored
upon entering test mode, and cleared when a vehicle speed signal of 12 mph (20
km/h) is detected for 3
seconds or more. The dtc is output only in test mode.
