Toyota RAV4 (XA40) 2013-2018 Service Manual: How to proceed with troubleshooting
Hint:
- Use these procedures to troubleshoot the tire pressure warning 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 indicator light
- Check the indicator light (see page tw-17).
- Check dtc*
- Check for dtc (see page tw-20).
- Clear the dtc (see page tw-20).
- Recheck for dtc (see page tw-20).
Result 
- Dtc chart
- Check for tire pressure warning system dtc output (see page tw-22).
- Problem symptom confirmation
- Problem symptoms table
Result
- Overall analysis and troubleshooting*
- Terminals of ecu (see page tw-16).
- Data list/active test (see page tw-21).
- Repair or replace
- Confirmation test

Description
Refer to dtc p0115 (see page es-105).
Monitor description
The resistance of the ect sensor varies in proportion to the actual ect. The
ect supplies a constant
voltage to the sensor and monitors the signal output voltage of the sensor. The
signal voltage output
varies acc ...
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.
