WS2 Flash Code
First thing we checked that the engine light is working by turning on the key, the ignition to be switched on, then start the engine and the light is off, that mean the engine is running at most efficient condition. If the engine is still On and flashing, that mean there is fault in the engine.
Second We turned off the key and connect the wire from TE1 to E1 then we turned on the ignition key and the engine light is flashing. Record how many flash you see. For example: it flash once then pause then flash another six times, it means 16. After previous step, looking for diagnostic fault codes sheet then you can see which system is faults.
First thing, we have a visual inspection on the engine and then we look on MAP. ECT, TPS. IAT sensor to fine any physical damage, corrosion, broken wire, leak hose, and bad connection. Another way, wires shorted to other wires or earth. or mechanical problems that will cause an electrical code. After that, we found they are not plug properly. If they are connected properly, we can use an oscilloscope to read the pattern signal from these sensor.
Repair fault:
To repair, we plugged these sensor connector back and start the engine to make sure the engine run properly.
5
Usually, after we fixed or replaced these faulty sensor. The engine light will stop flashing. However, there is another way to clear code by pulling the EFI fuse to clear code from memory or we can use the scan tool to clear the code.
6
After we cleared the code, the engine light stop flashing and no trouble code is shown. The result is no fault code.
7
The faults could affect the engine performance, by causing rough idle. Faulty MAP sensor may affect the engine performance, the engine will have rough idle, surging, rich mixture, spark plug fouling and loss of power due to retorted timing.
8
We can use the scan tool to check the fault code and match these flash code with scan code. Another way, we can test these sensor by using an oscilloscope to read their pattern and analyse. The pattern fro the oscilloscope show the real time numeric voltage data from these sensor, so we can compare these numeric data with specification data
