Toyota RAV4 Service Manual: How to proceed with troubleshooting
Hint:
Use these procedures to troubleshoot the engine immobiliser 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.
- crank engine for more than 10 seconds
- Check for dtc*
- Check for dtcs and make a note of any codes that are output (see page ei-18).
- Clear the dtc.
- Recheck for dtcs. Based on the dtc output above, try to cause the output of the same sfi system dtc or engine immobiliser system dtc by simulating the original activity indicated by the dtc.
