Toyota RAV4 (XA40) 2013-2018 Service Manual: Check for intermittent problems
- Check for intermittent problems
Hint:
A momentary interruption (open circuit) in the connectors
and/or wire harness between the sensors and ecus can
be detected by using the ecu data list function of an
intelligent tester.
- Turn the ignition switch off and connect the
intelligent tester (with can vim) to the dlc3.
- Turn the ignition switch on.

- Follow the prompts on the intelligent tester to
display the data list and select areas where a
momentary interruption should be monitored.
Hint:
- A momentary interruption (open circuit) cannot
be detected for 3 seconds after the ignition
switch is turned on (initial check).
- If the status remains on the error display,
check for continuity between the ecu and the
sensors, or between ecus.
- The error display on the intelligent tester
remains on for 1 second after the harness signal
changes from a momentary interruption (open
circuit) to normal condition.



- While observing the screen, gently jiggle the
connector or wire harness between the ecu and
sensors, or between ecus.
Ok:
error display does not change.
Hint:
The connector and/or wire harness have a
momentary interruption (open circuit) if the display
changes. Repair or replace the connector and wire
harness if either of them is faulty.
Hint:
Use these procedures to troubleshoot the vehicle stability
control system.
*: Use the intelligent tester.
