Roof switch turn around ?
Hi,
i have my convertible only since 2 month and i'm wondering why jaguar has programmed this roof switch this in my option wrong way.
I'm always pulling it to open the roof and the other way around.
Is there a simple way to change the direction of this switch? (by changing cables or so?)
Ok i've found a aftermarket roof module for about 500,- where you can change the direction, but i'm looking for a chaeper solution.
Thanks

The Jag orientation seems counter-intuitive to me as well. The button should match the directional motion of the roof mechanism. the roof doesn't move up and down, but rather back and forth. There are a couple of early threads debating this same issue. Fortunately, everyone wins this argument based on their own preferences.

I don't have a convertible to test with, but it looks like you may be able to just switch pins 3 (green with violet stripe) and pin 5 (blue with orange stripe) at the C3PR23 connector that plugs into the bottom of the switch.

I have the SmartTop controller, which lets me raise/lower the roof/windows, using the remote. It also lets me reverse the sense of the up/down switch, as I too find it a bit backwards. In later years, the use of the key fob got a bit more awkward due to changes Jag made to the bus protocol.

Same as the parking brake switch: UP to pull up on the brake (like an old fashioned lever PB 
), push DOWN to release.
(Wait until the OP wants to check his oil level, LOL)

I always release mine with the throttle pedal.

PS: the electric brake is useless for doing handbrake turns.
Guess I gotta borrow my friend's RWD '15 V8 S to keep in practice, LOL.

It's the first (slight) movement of the throttle pedal that releases it, so I don't think there's much additional wear.
I believe it’s force detected at the rear caliper that triggers the release. I can feel the resistance when I forget to release the brake. I can rev the engine all I want and it won’t release the brake.

OK, Parking Brake descriptions are in Section 206-05A of the shop manual posted in the STICKIES. (page 4684)
Release parameters are found 10 pages later. Quite impressive (and they are different for automatic VS manual transmission cars).

The EPB has lots of interesting modes...

Drive Away Release
With the vehicle stationary and the Electric Park Brake
applied, the Drive Away Release (DAR) mode will
gradually reduce the clamp load when the accelerator
pedal is pressed – without the EPB switch being set
to the release position – to assist with a smooth driveaway.
This mode is only active if either the driver door
is closed, or if the driver safety belt is buckled and the
engine is running.
The point at which the EPB module releases the
brakes is determined by the following factors:
• Tilt angle – from the inclination sensor in the EPB
module
• Engine torque – from the ECM
• Accelerator pedal applied – from the APP sensor
• D (drive) or R (reverse) selected – from the TCM
DAR operation can be delayed by holding the EPB
switch in the applied position, then releasing it at the
required time.
