Toyota RAV4 (XA40) 2013-2018 Service Manual: Check for intermittent problems
Hint:
Inspect the vehicle's ecm using check mode. Intermittent problems are easier to detect with the intelligent tester when the ecm is in check mode. In check mode, the ecm uses 1 trip detection logic, which is more sensitive to malfunctions than normal mode (default), which uses 2 trip detection logic.
- Clear the dtcs (see page es-35).
- Switch the ecm from normal mode to check mode using the intelligent tester (see page es-38).
- Perform a simulation test.
- Check and wiggle the harness(es), connector(s) and terminal(s).
How to proceed with troubleshooting
Hint:
*: Use the intelligent tester.
Hint:
If the display indicates a communication fault in the tester,
inspect the dlc3.
Hint:
Record or print dtcs and freeze frame data, if necessary. ...
