Just in case anyone does not.

see below.

Just like most other EMS.

Resetting kick down travel limits.

After battery reconnection, the engine management system must ‘re-learn’ the limits of throttle pedal travel.

This is to ensure correct adaptive settings are stored for kick down operation.

Re-programming is done with the ignition switch in positionII as follows:

Slowly press the accelerator pedal fully through the kickdown detent to the floor.

Release the pedal and repeat the action. Then stop.

Drive around a bit and you will see an improvement. If not re read the codes, and re-start and try again.

When replacing the battery, assuming it still has some residual charge, wouldn't it be worthwhile to connect a temporary 12 volt supply (or battery) across the leads so there's no loss of power during the change over?

Hi fluty,


Welcome to the Jaguar Forums! It's great to have you with us.

Yes, you make a good point that attaching a temporary 12 volt supply to the battery cables can obviate the need for resetting or recalibrating various systems whose keep-alive-memories are cleared when the battery is disconnected, and some Jaguar service documentation makes this recommendation. Unfortunately it won't help if the old battery becomes depleted prior to replacement. Also, there are certain operations such as alternator or starter replacement when connecting a charger or power supply would be inappropriate, since you don't want any voltage at all on the battery power cables.

When you get a chance, please visit the New Member Area - Intro a MUST and post a required introduction so we can learn something about you and your Jaguar and give you a proper welcome.

Cheers,

Don
