Hint
: the most difficult case in troubleshooting is when no symptoms occurs. In such cases, a thorough customer problem analysis must be carried out. Then the same or similar conditions and environment in which the problem occurred in the customer’s vehicle should be simulated. No matter how much experience a technician has, or how skilled he may be, if he proceeds to troubleshoot without confirming the problem symptoms, he will tend to overlook something important in the repair operation and make a wrong guess somewhere, which will only lead to a standstill. For example, for a problem which only occurs when the engine is cold, or for a problem which occurs due to vibration caused by the road during driving, etc., The problem can never be determined when the engine is hot or when the vehicles is at a standstill. Since vibration, heat or water penetration (moisture) is a likely cause for the problem which is difficult to reproduce, the symptom simulation tests introduced here are effective measures in a point that the external causes are applied to the vehicle in a stationary condition.
Important points in the symptom simulation test: in the symptom simulation test, the problem symptoms should be confirmed, and the problem area or parts must also be discovered. To do so, reduce the possible problem circuits according to the symptoms before starting this type of test and have the hand–held tester connected beforehand. After that, carry out the symptom simulation test, judging whether the circuit being tested is defective or normal and also confirming the problem symptoms at the same time. Refer to the problem symptoms table of each system to narrow down the possible causes of the symptom.
1. Vibration method: when vibration seems to be the major cause.
Hint
: applying strong vibration to relays may result in open relays.
The connector joint and fulcrum of the vibration are the major areas that should be checked thoroughly.
2. Heat method: if the problem seems to occur when the area in question is heated.
Notice
:
3. Water sprinkling method: when the malfunction seems to occur on a rainy day or in high–humidity.
Notice
:
Hint
: if a vehicle is subject to water leakage, the leaking water may contaminate the ecu. When testing a vehicle with a water leakage problem, this factor must also be considered.
4. Others: if the malfunction seems to occur when electrical load is excessive.
