If any folk on here have an IID tool and a L405 - have you ever had this error message if you try to set the parking brake into maintenance mode so you can change the rear pads?

"Operation failed E7"

- just to be clear I mean the IID tool giving the error message NOT the car.

thanks.

Best to check with GAP... .

Yes they are already looking into it for me but i wanted to know if anyone else had the same problem.

When I asked about E7 for the FBH, Gap said it just meant that the FBH didn't accept the command so possibly the same thing, the ABS ECU hasn't accepted the command you sent it. Current: RR L322 2010
Past: RR L405 2017, RR L322 2012, 2008 & 2004, 2018 D5, 2016 Defender, 2011 D4, a few Disco2s, P38, RR Classic, couple of Disco1's, SIII SWB

We’ve got to the bottom of this. The EPB must be off before selecting the Maintenance/ service option on the IID Tool. Then it’s all fine and dandy.

So what is E7 in relation to testing the FBH then? That’s what I’m currently trying to do. 2010 MY Vogue SE TDV8 3.6 Stornoway Grey- fully loaded

Following e7 for fbh I get the same with fault codes Flame out. And. Circulating fan electrical fault

Seen a few people here refer to IID tool. Isn't it an expensive tool ?

@jackcramer

I understand it is now @ £150 to put your FFRR into a main dealer to just have your codes read / diagnostics, and that is before any work is done (although they will ensure your car gets scratched by the handwashers later...

Now that is expensive.

An IIDTool (or similar) will pay for itself again and again over the lifetime of your ownership of an FFRR if you want to fix it yourself .

£180 + vat here in bristol

I told the dealer where to shove it and bought one straight away. Wished I’d done So years ago. Vital piece of kit.

Not sure if I can fix things as it is a complex vehicle. Most I can do is a service and brake change.

So a off the shelf OBD scanner won't do?

AFAIK a scanner will read fault codes.

An IID will read fault codes, but will also allow you to make changes to the CCF (Car Configuration File)
