For all others, GO to KB5 .<br />
KB5 CHECK THE B+ VOLTAGE TO THE FPDM POWER SUPPLY RELAY<br />
FPDM PWR Relay connector disconnected.<br />
Measure the voltage between:<br />
( + ) FPDM PWR Relay Connector, Harness Side ( - )<br />
B+ Ground<br />
Is the voltage greater than 10.5 V?<br />
GO to KB6 .<br />
Yes<br />
B+ circuit fault. CHECK the condition <strong>of</strong> the related fuse/fuse links. If OK, REPAIR<br />
the open circuit. If the fuse/fuse link is damaged, CHECK the circuit for short to<br />
ground before replacing.<br />
No<br />
KB6 CHECK THE VPWR VOLTAGE TO FPDM POWER SUPPLY RELAY<br />
Key ON, engine OFF.<br />
Measure the voltage between:<br />
( + ) FPDM PWR Relay Connector, Harness Side ( - )<br />
VPWR<br />
Ground<br />
Is the voltage greater than 10.5 V?<br />
GO to KB7 .<br />
Yes<br />
REPAIR the open circuit.<br />
No<br />
KB7 CHECK FOR GROUND TO THE FPDM POWER SUPPLY RELAY<br />
Measure the resistance between:<br />
( + ) FPDM PWR Relay Connector, Harness Side ( - )<br />
GND<br />
Ground<br />

GO to KB8 .<br />
Yes<br />
REPAIR the open circuit.<br />
No<br />
KB8 CHECK THE FPDM PWR CIRCUIT FOR AN OPEN IN THE HARNESS<br />
Measure the resistance between:<br />
( + ) FPDM Connector, Harness Side ( - ) FPDM PWR Relay Connector, Harness Side<br />
FPDM PWR<br />
FPDM PWR<br />
Is the resistance less than 5 ohms?<br />
Yes<br />
INSTALL a new FPDM relay. GO to KB9 .<br />
No<br />
KB9 ISOLATE THE OPEN IN THE FPDM CIRCUIT<br />
IFS Switch connector disconnected.<br />
Measure the resistance between:<br />
( + ) FPDM Connector, Harness Side ( - ) IFS Switch Connector, Harness Side<br />
FPDM PWR<br />
FPDMPWR-B<br />
Measure the resistance between:<br />
( + ) FPDM PWR Relay Connector, Harness Side ( - ) IFS Switch Connector, Harness Side<br />
FPDM PWR<br />
FPDMPWR-A<br />
Is the resistance less than 5 ohms?<br />
INSTALL a new IFS switch.<br />
Yes<br />
VERIFY the IFS switch is set (button pressed).<br />
REPAIR the open circuit.<br />
No
