Gauge button on always.

TP4, TP5, TP7, TP8, TP10, TP11, TP15, TP16, TP17, TP18, TP20, TP23, TP30

Read the following, ignition on, pre-crank:
TP4, TP5, TP7, TP8, TP10, TP11, TP15, TP16, TP17, TP18, TP20, TP23, TP30 (same as above)

Read the following, engine running:
TP4, TP5, TP7, TP8, TP10, TP11, TP15, TP16, TP17, TP18, TP20, TP23, TP30 (same as above)

Th One more picture of the whole board. The left side is missing.

Re: Failsafe with HKS EVC 6
 

Ok Richard thanks for your support, will test them in the next couple days and update this thread ...

Re: Failsafe with HKS EVC 6
 

OK. I look forward to the readings.

Can you take a hi-res, close up picture of the plugs of both gauge cable. Long and short. Make sure they are in focus.

Re: Failsafe with HKS EVC 6
 

Hi Richard, results are in, let me know what you think

Re: Failsafe with HKS EVC 6
 

Original cable end

Re: Failsafe with HKS EVC 6
 

Extended, other end is a mirror just like the original, both behave the same ..

Re: Failsafe with HKS EVC 6
 

One thing stood out on the tests, the red wire of the molex is not correct, Check this wire. Should be A8 of the DME.

Re: Failsafe with HKS EVC 6
 

It is connected to A8, in fact it is twisted with the other red wire from the ECU harness and tapped into A8 at the same exact point

I will check and adjust that wire, which test point to check after and what should the reading be?

Re: Failsafe with HKS EVC 6
 

I went back to the car rechecked the red wire from the molex connector and it is definitly in contact with the A8 pin wire ... I even untwisted it from the other red wire from the ecu harness and gave each wire its dedicated contact space on A8's wires ......

Still, the water level light remains, but I noticed this:


When the A connector of the car's ecu is disconnected the water level light goes away, but the gauge background and S led is still working, as soon as I plug in the A connector /harness the light comes back on again ...
