Battery Isolation Transit Relay

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2015 Jaguar XK, 2014 Jaguar XKR-S, and 2014 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.

A transit relay is connected to the battery to reduce voltage loss and prevent the battery becoming discharged. This allows the vehicle to be driven when necessary, but isolates the battery from the vehicle during transit and storage.

The transit relay is connected between the battery positive post and the battery positive lead. When the ignition is switched off, the transit relay isolates the positive side of the battery. When the ignition is switched on, a signal is applied via the auxiliary connector to close the positive side of the battery circuit.

CAUTION: Damage to equipment. Failure to remove the transit relay before carrying out the PDI checks may result in damage to IDS equipment.
Do not leave the ignition switched on for extended periods.

The PDI checks specified in this document MUST be carried out with the transit relay removed (refer to 'PREPARATION - BATTERY TRANSIT RELAY REMOVAL AND BATTERY RE-CONNECTION '), and the ignition switched on for limited periods (where applicable).
