I can never be 100% until it is tested. Please update.

Re: Failsafe with HKS EVC 6
 

Hello Richard ...

Ive installed e hfs3 on the car now, i still have the stock turbo setup and want to test that the system works on this setup first, and I have run into a couple of problems:

1- water level light on the gauge is always on, level sensor is correctly installed and all wiring is in order .... could it be a faulty sensor? I cannot begin to purge the system as it wont start the pump even with the sys jumpers.


2- The green idc led is not coming on. I tripple checked the idc connection on the ecu end. The amber thresh led comes on when I blip the throttle, green led never came on. When testing wi th the idc jumper on the circuit board the s+b lights on the gauge do flicker with throttle blipping.
So do I have a faulty green led on the circuit board too?


Any help is apprecited ...

Re: Failsafe with HKS EVC 6
 

Ive been troubleshooting with Jeff and learned a few things

1- the green led is definitly not working. Hooked the green wire from the ecu harness to ground and only the amber and red lights came on

2- pump works no problem, hooked direct to battery and runs

Wiring and circuit board seems fine but the water level light would not go away even with the sensor disconnected!!

What else would trigger that light?

Check this short video of the gauge

Re: Failsafe with HKS EVC 6
 

Please give me the following answers:

1. Which version is the HFS3?
2. serial number.
3. What wiring diagram are you using?
4. Is this a new install
5. Is the water level sensor installed in the correct orientation? Does the lever points upwards 45 degrees when tank is full?

Hi Richard,

1- V3
2- sn: 102169
3- view attachment
4- yes this is a new install
5- yes it is, while on the matter, the reccomended 22-23mm hole in the manual will not work and the rubber gromet will pull through, a 16-17mm hole will allow the gromet to compress properly into an oring to seal.

Re: Failsafe with HKS EVC 6
 

Took a closer look at the circuit board, and the plastic base of the dfs jumper is partially broken. Could this cause the issue?

I have not tested the system on the road yet btw.

Let's deal with the tank level led.
(Let me have the results)

1. Unplug the sensor in the trunk.... is the led still on?
2. Still unplugged, now plug the blue harness from the controller.... result?

Await your reply.

Re: Failsafe with HKS EVC 6
 

I have tried that already while troubleshooting with jeff, no change . The water level light stayed on and the green led on the controller never came on ..

Re: Failsafe with HKS EVC 6
 

I just tried this Richard, I plugged in only the essentials .. Gauge, power and ecu, only with these 3 the gauge would come on ... 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?
