Hi Everybody,
I have both an Original Bosch VCI working with a Regular independent account on Topix and also I have a IID4 (I use it to reed live parameter and to modding the CCF).
On my L663 Hybrid P400e in august I have modified this CCF parameter (I always use a BSU when modding CCF):
- MultiCAN717 FrontBeltMinder
- MultiCAN770 RemoteRelease Tailgate
The procedure was done ok with no error.
Immediately after upload the CCF modded with IID4 I have lock the door and wait until 3 minutes, then I unlock and switch on the ignition.
Everything seems ok.. but…
After one day come out the problem…!!!
The EV mode result unavailable and the DTC “B1DC5-93 High Voltage Coolant Heater - No operation” come out.
I’ve tried to reset the HVAC it with VCI and Topix with not results.
I have used Topix with this two tools:
- HVAC - Unlock High Voltage Coolant Heater - G3204479 - v9.0
- HVAC - Clear Event Data - G3290956 - v1.0
With not result.
When the problem come out I don’t connect that the problem on the High Voltage Coolant Heater is related to the CCF modding…
So I contact my Land Rover dealer.
The problem is solved by the Dealer. It was necessary change the High Voltage Coolant Heater.
Two days ago I have modified the CCF (I’d like to disable the fake motor sound)
MultiCAN-584 NextGenPwrTrnSQ - set: Not Fitted
MultiCAN-585 ActSndDesignPwrlvl - Set: Not Fitted
And now… here again.... The DTC “B1DC5-93 High Voltage Coolant Heater - No operation” come out again!!!!!!
​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​
Any idea how to solve it???
Maybe an hardware reset of the High Voltage Coolant Heater?
But How??I don’t want to change another High Voltage Coolant Heater….…
Thank You

 

Sounds like a coincidence. Those parameters you are changing have no impact on the high voltage coolant heater. I bet you have a different issue that has caused it both times.

Get the high voltage heater fixed again, do not apply CCF changes for a month and see if it breaks again in that timeframe.
If your service department is good they will start looking upstream of the heater to see what's causing the problem.

Not sure how you are using both the Bosch and the GAP tool together, but that could introduce a variable that most users wouldn't see.

 

I do love a good mystery.

I'd agree, straight back to the dealer, I would avoid full disclosure ie do *not* tell them of your CCF modifications... have them fix it, sit on your hands for 30 or 60 days... see what happens.

If nothing happens.. I might think twice about doing any further CCF edits. For a while.

I would report this to the lovely chap Patrick (is that his name) at Gaptool's company, he is quite technical, and he might be interested to hear about this, even if it is just a coincidence. Just to plant the seed in case other customers have the same issue. I would bet you are not the only one who is having a go at the CCF on his/ her P400e. that said P400e is a bit more rare, so maybe you're the first?

 

Before I bought the IID4, I have modded the CCF al lot of time on my P400e using a Pathfinder with no problem.
The problem was done from the IID4....

I stil investigate how solve it (without dealer)...
