Toyota RAV4 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.
