1998 JAGUAR X308 relay

Wi
th the ignition energized, measure the current drawn
between relay socket pins 3 and 5.

Is
the current between 2.5 and 9 A?
Yes GO to B7
No GO to B10

W
ith EM013 disconnected, measure the resistance
between EM013/009 and relay socket pin 1
1
I
s the resistance < 0.5 OHM?
Yes GO to B9
No Inspect connectors EM013, EM051/008, LS003/21,
BT004/009 and BT010/005 for corrosion, damage, bent or
pushed back pins and repair as required. Test the system
for normal operation
B9: CHECK
ECM GROUND CONTINUITY

Wi
th EM014 disconnected, measure the resistance
between EM014/010 and ground EM016L.
1
I s
the resistance < 0.5 OHM?
Yes STOP, renew the relay and test the system for normal
operation.
No Inspect harness / connectors EM014, splice EMS37 and
ground EM016L for corrosion, damage, bent or pushed
back pins. Repair as requir ed and test the system for
normal operation.
B10: CHECK FU EL
PUMP 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.

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
