box JAGUAR XFR 2010 1.G Workshop Manual

a power supply to operate the glovebox latch to unlock the glovebox.

The glove box opening is inhibited by the CJB if the anti-theft alarm system is armed and if valet mode is selected using the Touch Screen Display (TSD). The CJB detects the voltage signal from the switch but will not operate the glovebox latch if other condition exists.



GLOVEBOX SWITCH DESCRIPTION Component Description

The conventional glove box switch is located behind the instrument panel veneer. The round button of the switch is visible
through an aperture in the veneer.

Two screws hold the switch in position behind the veneer. The veneer panel has two bosses which the screws are threaded
into.

Operation section of the workshop manual. REFER to: Handles, Locks, Latches and Entry Systems (501-14, Description and
Operation).

Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle


NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests

1. Verify the customer concern, to be sure the correct issue is investigated
2. Visually inspect for obvious signs of damage and system integrity

Visual Inspection
Mechanical Electrical
Incorrectly aligned door(s), hood or tailgate
Fuel filler door lock actuator
Hood release handle
Hood release cables
Hood latch(es)
Exterior door handle(s)
Interior door handle(s)
Cable(s)
Tailgate release switch
Rear window release switch
Fuses
Wiring harness
Wiring connector(s)
Door lock actuator(s)
Remote transmitter (key-fob or smart key)
Central locking switches
Controller Area Network (CAN) circuits
Radio frequency (RF) receiver
Central junction box (CJB)
Loose or corroded connections
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step

4. If the cause is not visually evident verify the symptom and refer to the Symptom Chart, alternatively check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index
Symptom Chart


NOTE: Complete the diagnostic steps below to confirm any concern prior to replacing any component

Symptom Possible Causes Action The message center indicates that the
hood, the luggage compartment is
open when it appears to be closed
Incorrect striker
alignment/adjustment
Ajar switch circuit short circuit to
ground
Ajar switch failure
Check/adjust the strikers as
necessary
Check for DTCs indicating an ajar
switch fault. Refer to the DTC index Vehicle indicates a miss-lock when the
hood, luggage compartment appear to
be closed Fuel flap does not lock/unlock
Fuel flap cable detached from body
Fuel flap actuator detached from
mounting bracket
Fuel flap actuator disconnected
Fuel flap actuator failure
Check the condition and installation
of the fuel flap cable
Check the security of the fuel flap
actuator and bracket
Check the security of the actuator
electrical connector
Check for DTCs indicating a fuel flap
actuator fault. Refer to the DTC
index Door(s) will not unlatch/open when
using outside door handle
Exterior door handle
condition/installation
Exterior release cable disconnected
from exterior door handle or door
latch
Check the exterior door handle

Symptom Possible Causes Action outside (but opens from the
inside) GO to Pinpoint Test A. Door(s) will not unlatch/open when
using inside door handle
Child lock(s) engaged
Interior door handle
condition/installation
Interior release cable disconnected
from interior door handle or door
latch
Check that the child locks are
disengaged
Check the interior door handle
condition and installation
Check the condition and security of
the interior release cable

Pinpoint Test

PINPOINT TEST A : SINGLE DOOR WILL NOT OPEN FROM THE OUTSIDE (BUT OPENS FROM THE INSIDE) TEST CONDITIONS DETAILS/RESULTS/ACTIONS A1: CHECK THE EXTERIOR DOOR RELEASE CABLE TO EXTERIOR DOOR HANDLE IS INSTALLED CORRECTLY

1 Remove the door trim panel as necessary 2 Confirm the exterior door release cable is correctly installed to the exterior door handle Is the cable correctly installed?
Yes
GO to A2. No

Body wiring harness / connectors
Door wiring harness / connectors
Alarm control module
Central junction box (CJB)
Door Latch ajar switch
To investigate the functioning of the door ajar switch contained within the door latch, to prove or eliminate the door
latch mounted door ajar switch as the root cause, follow the process below. This will prevent the unnecessary replacement of
a correctly functioning door latch 1 Remove door trim from door 2 Disconnect door harness from latch for access to connector pins for latch electrical testing 3 Inspect latch module for any visual damage NOTES:


Figure 1 - Unlatched position shown


Figure 2 - First safety latched position shown


Figure 3 - Fully latched position shown


Test will not work if latch is only in first safety latch position 4 Using a small screw driver or similar, rotate latch claw to the second fully latched position (figure 3)

5 Carry out continuity test between terminals 1 and 4 (left side) or 8 and 4 (right side) with claw closed Does the continuity test pass? Yes
The latch ajar switch is working correctly. Do not replace latch.
Investigate for fault elsewhere in vehicle system

Wipers and Washers - Wipers and Washers - Overview
Description and Operation

OVERVIEW Published: 11-May-2011

The wipers and washers comprise a windshield wiper system with a conventional wiper linkage and 2 wiper blades and a
windshield washer with jets located on the wiper arms. A headlamp powerwash is available on certain models.
The front wipers have 4 operational states:
Flick wipe
Auto
Slow wipe
Fast wipe.

Operation of the windshield wipers and washers and the headlamp powerwash is controlled by the CJB (central junction box) in
response to driver inputs and signals from the rain/light sensor. The instrument cluster monitors the condition of the
wiper/washer control switch and transmits driver requests to the CJB over the medium speed CAN (controller area network) bus.

The 'Auto' function requires an input from the rain sensor. The rain sensor is mounted on the inner surface of the windshield
and transmits an infra-red signal to determine the amount of water on the outer surface of the windshield. A value is then
transmitted to the CJB over the LIN (local interconnect network) bus.
