Hint:
Perform troubleshooting in accordance with the following flowchart.
*: 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.
- Problem symptom confirmation
- Check can communication system*
- Check for dtc (see page ps-11).
Result 
Hint:
- When any can communication system dtcs are output, perform troubleshooting on the can communication system first.
- When communication to the power steering ecu is not established through the intelligent tester, inspect terminals sil of the dlc3 and the power steering ecu, and the ig circuit of the power steering ecu.
- Check dtc*
- Check for dtc (see page ps-11).
