Failsafe with HKS EVC 6

[Richard L]

I am still on the first issue of the yellow led.

So, when you pulled the blue harness, the yellow led still on?

Yes Richard ...

Actually no matter what harness you plug or unplug that light never goes off .. And I think if the system starts with it on it will never spray ...

White background is on with the yellow water level led, no other led is on, only the white background lettering ... Adding the blue plug with or without the sensor makes no change ... S led comes on with the wfs plug, ans the B with throttle ..

Have not yet tried it on the road, I stopped when I could not jump the pump manually from the box.

In the manual it says if the DFS jumper is linked this light will stay on as reminder, since the base is broken could that cause some sort of link between the poles?

What else would trigger this light so early?

Suggestions?

Please, please one thing at a time...

Just to recap:
Gauge ...... plugged in
Molex power ...... plugged in
ECU harness ....... plugged in


With the above, gauge back light comes on, and the yellow led also comes on.

Is this correct?

The plastic base on the PRK has nothing to do with the issue.

Yes ..........

OK, thank you.

This cannot happen unless there are some damaged components. Can you take a hi-resolution picture of the underside of the circuit board. I like to see if there are signes of damage.

BTW, do you have a digital multimeter?

[P997.tt]

Yes I do have a multimeter ..

Give me a minute to get the controller pics

[Richard L]

Great, the multimeter will help a lot.

There are 30 test points on the circuit board. All voltages. The ground (black probe) is at the bottom left of the 2nd row of test points. Let me know if you have identified this "ground" point.

Yeah, clear in the picture ...

So black to ground and red to test point ... Which points you want me to test? All 30?
