CHECK FOR INTERMITTENT PROBLEMS
1. 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 ECU 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.

(f) While observing the screen, gently jiggle the connector or wire harness between the ECU and sensors, or between ECUs.
OK:
Normal display appears.
HINT:
The connector and/or wire harness has a momentary interruption (open circuit) if the display changes. Repair or replace the connector and/or wire harness as one of them is faulty.
