Pinpoint test E: P0702
With EM062 disconnected, measure the resistance
between the following, noting the relevant DTC 1
For P0702 or P0748 EM062/38 and EM062/036 2
For P0702 or P1748 EM062/38 and EM062/037 3
Is the resistance 16 to 18 kOHM?
Yes Reconnect EM062
GO to D9
No Renew the Valve Body Assembly; refer to 44.40.01.
Drive the vehicle for a period from cold to include idle,
brisk acceleration and steady state cruising up to and
including normal engine temperature.

• NOTE: Battery and or ECM disconnection prior to scanning wi ll erase all data, ensure that the correct DTC is present.
detectable difference in the voltage reading (due to minimal current flow); if there is a detectable difference, clean the cable terminal and the adjacent area of the body.
When the voltage has been measured, STOP THE ENGINE.
Reconnect the battery or fit a new battery if it was established that the battery was at fault (Refer to 414-01).
If the cooling fans operate during the above test, the large demand of current will overload the generator and cause the
engine to stall.
If the battery is in a low state of charge the voltage will rise momentarily when the battery is disconnected. However, the
maximum that the voltage can increase to with this new gene rator is 25V and then only for a maximum time of 200 mS.
Using a Substitute Battery
A substitute battery may be fitted for the tests. This batter y must be a known good example and must have been off-charge for at least twelve hours, with a term inal voltage of approximately 12.8V.
Ensure that all electrical loads are swit ched OFF and that the engine is cool.
Start the engine and allow to IDLE.
Measure the voltage across the battery term inals. It should have dropped a little due to the large start current and then
risen to a value of between 13V and 15V.
If the above test (whichever one used) indicates that the generator is not working then the connections on the rear face of
the generator should be checked. If there is a faulty connection, then the ge nerator will not perform correctly no matter
how fast it is driven.

Description and Operation
Door Lock Mechanism
For most markets, the remote central locking system also, in corporates deadlocking facilities for optimum security. Door
locks are eight disc, bayonet fixing barrels with integral lock / unlock switches. Keys include 'in-key' transponders which are
programmed to the vehicle via the Jaguar Diagnostic Sy stem and operate the engine immobilisation system.
The central locking system employs single key access to the driv er's door, trunk lid and ignition switch/steering column lock.
An additional green headed valet or park ing services key permits access via the driver's door, and ignition/start-up, but
denies access to the trunk and glovebox.A valet switch located on the centre console switch panel above the radio,
precludes normal internal access to the trunk.When the vehicle is not locked, each door catch can be externally released by
the corresponding external door handle which operates via a si ngle rod. When unlocked, or 'single action' locked, the door
catches can also be released via the interior handles, each of which operates via a single cable. Operation of the front door
interior handles will also unlock the rear doors. Use of either key in the external door barrel, operates the lock via a short
rod to provide locking of the door latch. These locking functions can also be achieved by use of the remote transmitter.The
trunk lid can be independently unlatched via a switch located on the driver's side underscuttle. This will only operate at
vehicle speeds up to 8 km/h (5 mph).
All doors and the trunk can be manually lock ed simultaneously from inside by pressing the driver or front passenger door sill
button down. Each rear door can be independently locked by si milarly depressing the sill button and in some markets can be released by operating the internal door handle.
For most markets, a 'drive-away door locking' feature automati cally locks all doors and the trunk when the gear selector is
moved from the Park position.
Key Operation
To 'single action' lock or unlock the vehicle, the key is inserted in the door lock , turned towards the front or rear of the
vehicle respectively, and released. Holding the key in the lock position will close all windows. Releasing the key stops all
operations. 'single action' locking of the vehicle locks all doors, the trunk lid and the fuel filler flap, and sets the alarm
system.
In addition to all of the above functions, deadlocking prevents door opening from th e interior. To deadlock the vehicle, the
key is inserted in the door lock and turned to the unlock (rearw ard) position, then within three seconds, turned to the lock
(forward) position and released.
