CHECK BATTERY CURRENT
• ACTIVATION: With all circuits off, current flow of more than +1.5 to -2.0 amps is detected in the 12 VDC
electrical circuits. NOTE: If this alarm occurs, Pretrip Test #2 will be skipped and Pretrip Test #3 will start.
• UNIT CONTROL: Engine and Electric Operation: Pretrip will fail and display “PRETRIP FAIL AND COM-
PLETED”.
• RESET CONDITION: Auto reset if Pretrip is started again, or alarm may be manually reset using the dis-
play mounted keys or by turning the unit off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, clear the
alarm(s). (Refer to Note 1 in
Section, page 7-2.) Operate the unit through the appropriate modes to see if
any active alarm occurs. Continue with the steps below as necessary.
CORRECTIVE ACTIONS:
1.
Check DC Current Draw and Sensor
a. Observe current draw reading in unit data. Reading must be b1.5 to -2.0 Amps.
b. Check power between 2MM-29 and 2MM-23 and between PCM-31 and PCM-30 5 VDC. If not,
check connectors and wiring between terminals for damage, moisture or corrosion.
c. Check for continuity from 2MM-12 to PCM-29. If good continuity not present, check connectors
and wiring between terminals for damage, moisture or corrosion.
2.
Check Individual Circuits
Isolate individual circuits and test amp draw. Must be in range. (Refer to
for correct
electrical values.)
3.
Check For Parasitic Loads
Check for electrical loads that are drawing current with all circuits OFF Check for non-factory
installed devices such as lift gates, inside lights, satellite systems, etc. These devices must be wired
so as to not draw current during Pretrip testing.

CHECK AMBIENT AIR SENSOR
• ACTIVATION: Ambient Air Temperature Sensor (AAT) is not within the range of -53 to +158°F (-47 to
+70°C).
• UNIT CONTROL: Engine and Electric Operation: Pretrip will fail and display “PRETRIP FAIL AND COM-
PLETED”.
• RESET CONDITION: Auto reset if Pretrip is started again, or alarm may be manually reset using the dis-
play mounted keys or by turning the unit off, then back on again.
CORRECTIVE ACTIONS:
1.
Check sensor operation
Refer to procedure for alarm
00121 CHECK AMBIENT AIR SENSOR
. Alarm condition must be cor-
rected and the alarm cleared to continue.
