Hyundai Tucson: Intermittent Problem Inspection Procedure
Sometimes the most difficult case in troubleshooting is when a problem symptom occurs but does not occur again during testing. An example would be if a problem appears only when the vehicle is cold but has not appeared when warm. In this case, the technician should thoroughly make out a "Customer Problem Analysis Sheet" and recreate (simulate) the environment and condition which occurred when the vehicle was having the issue.
- Clear Diagnostic Trouble Code (DTC).
- Inspect connector connection, and check terminal for poor connections, loose wires, bent, broken or corroded pins, and then verify that the connectors are always securely fastened.
- Slightly shake the connector and wiring harness vertically and horizontally.
- Repair or replace the component that has a problem.
- Verify that the problem has disappeared with the road test.
- Simulating Vibration
a. Sensors and Actuators
: Slightly vibrate sensors, actuators or relays with finger.
WARNING
Strong vibration may break sensors, actuators or relays
b. Connectors and Harness : Lightly shake the connector and wiring harness vertically and then horizontally.
- Simulating Heat
a.Heat components suspected of causing the malfunction with a hair dryer or other heat source.
WARNING
- DO NOT heat components to the point where they may be damaged.
- DO NOT heat the ECM directly.
- Simulating Water Sprinkling
a. Sprinkle water onto vehicle to simulate a rainy day or a high humidity condition.
WARNING
DO NOT sprinkle water directly into the engine compartment or electronic components.
- Simulating Electrical Load
a.Turn on all electrical systems to simulate excessive electrical loads. (Radios, fans, lights, rear window defogger, etc.)
