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

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.
