Is the voltage less than 1 V?<br />
INSTALL a new FPDM.<br />
Yes<br />
REPAIR the short circuit to GND.<br />
No<br />
KB43 CHECK THE REM/FP PWR AND GROUND CIRCUIT TO REM PINS J1-1, J1-2<br />
Note: Verify the IFS switch is not tripped.<br />
REM-J1 connector disconnected.<br />
Key ON, engine OFF.<br />
Measure the voltage between:<br />
( + ) REM-J1 Connector, Harness Side ( - ) REM-J1 Connector, Harness Side<br />
REM/FP PWR<br />
GND<br />
Is the voltage greater than 10.5 V?<br />
Key in OFF position.<br />
Yes<br />
No<br />
For these applications, the FPDM functions are incorporated into the REM. In the<br />
following steps, if directed to carry out an action with the FPDM, carry out the action<br />
with the REM.<br />
GO to KB44 .<br />
GO to KB33 .<br />
KB44 CHECK THE REM/FP PWR CIRCUIT VOLTAGE TO THE REM USING CHASSIS GROUND AS A REFERENCE<br />
Key ON, engine OFF.<br />
Measure the voltage between:<br />
( + ) REM-J1 Connector, Harness Side ( - )<br />
REM/FP PWR<br />
Ground<br />
Is the voltage greater than 10.5 V?<br />
REPAIR the open circuit.<br />
(Open FPDM ground circuit).<br />
Yes<br />
Key in OFF position.<br />
GO to KB45 .<br />
No<br />
KB45 CHECK THE B+ VOLTAGE TO THE FP/REM POWER SUPPLY RELAY<br />
FP/REM PWR Relay connector disconnected.<br />
Measure the voltage between:<br />
( + ) FP/REM PWR Relay Connector, Harness Side ( - )<br />
B+ - Pin 3 Ground<br />
Is the voltage greater than 10.5 V?<br />
GO to KB46 .<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 />
KB46 CHECK FOR IGN START/RUN VOLTAGE (THROUGH THE IFS SWITCH) TO THE RELAY HARNESS CONNECTOR<br />
REM-J3 connector disconnected.<br />
Key ON, engine OFF.<br />
Measure the voltage between:<br />
( + ) FP/REM PWR Relay Connector, Harness Side ( - )<br />
IGN START/RUN - Pin 2<br />
Ground<br />
Is the voltage greater than 10.5 V?<br />
Key in OFF position.<br />
GO to KB47 .<br />
Yes<br />
ISOLATE the concern,<br />
GO to KB51 .<br />
No<br />
KB47 CHECK THE GROUND CIRCUIT TO FP/REM PWR RLY<br />
Measure the resistance between:
