| Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM (w/o Electric Parking Brake System): CHECK FOR INTERMITTENT PROBLEMS; 2018 - 2020 MY Camry [06/2017 - 10/2020] | ||
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 using the Data List function of the Techstream.
(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON.
(d) Turn the Techstream on.
(e) Follow the directions on the Techstream to display the Data List and select areas where momentary interruption should be monitored.
HINT:
- A momentary interruption (open circuit) cannot be detected for 3 seconds after the ignition switch is turned to ON (initial check).
- If Error remains displayed for one of the items on the Techstream, check for continuity between the ECU and the item for which Error is displayed.
- If a momentary interruption occurs and Error is displayed on the Techstream, Error will remain displayed on the Techstream for 1 second after the circuit returns to normal.

(f) While observing the screen, gently jiggle the connector or wire harness between the ECU and sensors, or between ECUs.
OK:
Normal is displayed.
HINT:
If the display changes, this indicates that there has been a momentary interruption (open circuit) in the connector and/or wire harness. In this case, repair or replace the connectors and/or wire harnesses as one of them is faulty.
