Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
1.(F855) 5-VOLT SUPPLY CIRCUIT SHORTED TO BATTERY NEGATIVE
Turn the ignition off.
Disconnect the ECM harness connectors.
Disconnect the APPS harness connector.
Check connectors - Clean/repair as necessary.
Measure the resistance of the APPS1 (F855) 5-volt supply circuit
between the sensor harness connector and battery negative
Is the resistance greater than 100 k ohms?
Ye s>>
Go To 2
No>>
Repair the (F855) 5-volt supply circuit shorted to battery
negative.
Perform POWERTRAIN VERIFICATION TEST VER - 1
(DIESEL). (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/ENGINE CONTROL MODULE - DIAG-
NOSIS AND TESTING)

2.(F855) 5-VOLT SUPPLY CIRCUIT SHORTED TO OTHER CIRCUITS
Measure the resistancebetween the (F855) APPS 1 5-volt supply circuit
at the ECM harness connector and all other circuits in the ECM con-
nector.
Is the resistance greater than 100k ohms?
Ye s>>
Go To 3
No>>
Repair the APPS #1 (F855) 5-volt supply circuit shorted to
other circuits.
Perform POWERTRAIN VERIFICATION TEST VER - 1
(DIESEL). (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/ENGINE CONTROL MODULE - DIAG-
NOSIS AND TESTING)
3.INTERNAL ECM
Reconnect the ECM harness connectors.
Turn ignition on, engine off.
While monitoring with the scan tool, connect a jumper wire between the
(K23) APPS 1 signal circuit at the sensor harness connector and the
(F855) APPS 1 supply circuit at the sensor harness connector.
NOTE: With the APPS disconnected it is normal to have a APPS 1
and APPS 2 low voltage DTC set.
Did a APPS 1 voltage too high DTC set?
