JAGUAR X308 1998 2.G Workshop Manual

Wi
th BT009 disconnected, measure the resistance across
the fuel pump connectors reference BT009/003 and
BT009/004.
1
I
s the resistance < 5 OHM?
Yes GO to B11
No Renew the fuel pump and te st the system for normal
operation.
B11: CHECK FU
EL PUMP GROUND CONTINUITY

With
BT009 disconnected, measure the resistance
between BT009/003 and ground BT020L.
1
I s
the resistance < 0.5 OHM?
Yes GO to B12
No Inspect harness / connector BT009, splice BTS021 and
ground BT020L for corrosion, damage, bent or pushed
back pins. Repair as requir ed and test the system for
normal operation.
B1 2
: CHECK CIRCUIT CONTINUITY

Wi
th BT009 disconnected an
d relay 1 removed, measure
the resistance between BT009/004 and relay socket pin
5.
1
I
s the resistance < 0.5 OHM?
Yes GO to B13
No Inspect harness / connector BT 009, fuse holder F15 and
BT012/002 for corrosion, damage, bent or pushed back
pins. Repair as required and test the system for normal
operation.
B13: CHECK HARNESS SHO
RT TO GROUND

Wi
th EM013 and BT009 disconnected, measure the
insulation resistance between EM013/009 and ground
BT020L.
1
I s
the resistance > 10M OHM?
Yes Do not replace relay or reconnect connectors
GO to B14
No Inspect harness / connec tors EM013, EM051/008,
LS003/021, BT004/009 and BT010/005 for corrosion,
damage, bent or pushed back pins. Repair as required
and test the system for normal operation.
B1 4
: CHECK CORE TO CORE INSULATION

With
conditions as B13, meas
ure the insulation resistance
between EM013/009 and relay socket pin 5.
1
I
s the resistance > 10M OHM?
Yes GO to B16
No Inspect harness / connec tors EM013, EM051/008,
LS003/021, BT004/009, BT012/002, BT009/004 and
BT010/005 for corrosion, damage, bent or pushed back
pins and repair as required. Test the system for normal
operation
B1
5: CHECK CORE TO CORE INSULATION

Pinpoint test C: P0460
Wi
th conditions as in B14, measure the insulation
resistance between EM013/009 and BT009/003.
1
I s
the resistance > 10M OHM?
Yes Reconnect all plugs and replace relay 1.
GO to B16
No

C2
: CHECK CONTINUITY FUEL SENSOR
W

ith connectors BT014 and BT015 disconnected check
the resistance between the fuel level sensor pins.
1
Is
the resistance >70 and <1000 OHM?
Yes GO to C3
No Renew the level sensor and test the system for normal
operation.
C3
: CHECK FOR SHORT TO GROUND

Wi
th connectors FC025, FC024, BT014 and BT015
disconnected measure the insulation resistance between
FC025/013 and FC024/026.

Is

the resistance > 10 MOHM?
Yes GO to C4
No Inspect harness / connectors FC025, FC024, FC001,
BT004, BT014 and BT015 for corrosion, damage, bent or
pushed back pins. Repair as required and test the system
for normal operation.
