Toyota RAV4 (XA40) 2013-2018 Service Manual: Starter relay circuit high
![Toyota RAV4. Starter relay circuit high](images/books/256/16/1.htm91.gif)
Description
While the engine is being cranked, the positive battery voltage is applied to
terminal sta of the ecm. If
the ecm detects the starter control (sta) signal while the vehicle is being
driven, it determines that there
is a malfunction in the sta circuit. The ecm then illuminates the mil and sets
the dtc.
This monitor runs when the vehicle is driven at 20 km/h (12.4 Mph) for over 20
seconds.

Inspection procedure
Hint:
- Read value using intelligent tester (starter signal)
- Connect the intelligent tester to the dlc3.
- Turn the ignition switch on and turn the tester on.
- Select the following menu items: diagnosis /
enhanced obd ii / data list / primary /
starter sig.
- Check the value displayed on the tester when the
ignition switch is turned to the on and start positions.
![Toyota RAV4. Read value using intelligent tester (starter signal)](images/books/256/16/1.htm101.jpg)
- Inspect park/neutral position switch assembly
- Disconnect the b26 pnp switch connector.
- Measure the resistance when the transmission gear
selector lever is moved to each position.

Steering angle sensor circuit malfunction
Description
The steering sensor signal is sent to the skid control ecu via the can
communication system. When
there is a malfunction in the can communication system, it is detected by the
steering sensor zero point
malfunction diagnostic function.

Data list / active test
Read data list
Hint:
Using the intelligent tester's data list allows switch,
actuator and other item values to be read without
removing any parts. Reading the data list early in
troubleshooting is one way to save time.
Connect the intelligent tester (with can vim) to the
dlc3.

Description
This dtc is output when the vsc system has a problem. Check the vsc system
when this dtc is
output.
