Troubleshooting Test Steps
Values Results
1. Check For Active Diagnostic Codes
A. Turn the keyswitch to the OFF position.
B. Connect the electronic service tool to the diagnostic
connector.
C. Turn the keyswitch to the ON position.
D. Use the electronic service tool to check that coolant tem-
perature, intake manifold air temperature, and NRS tempera-
ture are all at least 5° C (41° F).
Note: Wait at least 10 seconds in order for the diagnostic co-
des to become active.
E. Use the electronic service tool in order to monitor active di-
agnostic codes or recently logged diagnostic codes. Look for
an active or logged -3 or -4 codes for the pressure sensor or
the barometric pressure sensor.
F. Use the electronic service tool in order to monitor active di-
agnostic codes or recently logged diagnostic codes. Look for
an active or logged -13 code for a pressure sensor or the baro-
metric pressure sensor.
G. Turn the keyswitch to the OFF position.
Diagnostic codes Result: There are no active diagnostic codes for the
pressure sensors.
Repair: If there are logged diagnostic codes for the in-
take manifold pressure sensor, the fault may be
intermittent.
Refer to Troubleshooting, “Electrical Connectors - In-
spect” in order to identify intermittent faults.
Result: One or more of the temperature sensors is read-
ing less than 5° C (41° F).
Proceed to Test Step 2.
Result: There is an active -3 or -4 diagnostic code for a
pressure sensor or the barometric pressure sensor.
Repair: Troubleshoot these codes before continuing
with this procedure.
Result: 3358-13 (3385-13) and 3563-13 (1785-13) diag-
nostic codes are active.
Proceed to Test Step 3.
Result: There is an active -13 diagnostic code for only
one sensor.
Proceed to Test Step 4.
2. Ensure that the Systems are Fully Thawed
A. Move the machine into an environment where the ambient
temperature is greater than 5° C (41° F) for the duration of
any troubleshooting.
B. If engine has been operated or stored in cold ambient con-
ditions where there is a risk of ice formation on a sensor or
sensor pipes, run engine until the coolant temperature ex-
ceeds 65° C (149° F) for 20 minutes.
C. Turn the keyswitch to the OFF position. Wait for at least 20
seconds. The electronic service tool will disconnect.
D. Turn the keyswitch to the ON position.
E. Verify that coolant temperature, intake manifold air temper-
ature, and NRS temperature are all now at least 5° C (41° F).
F. Check for active -13 diagnostic codes.
G. Check that the suspect sensor is installed correctly. Check
that the suspect sensor is fully seated into the engine.
Diagnostic codes Result: There are no active -13 codes.
Repair: The fault was caused by ice in the system that
has now been thawed. Return the unit to service
Result: Both 3358-13 (3385-13)and 3563-13 (1785-13)
codes are active or logged.
Proceed to Test Step 3.
Result: A single -13 code is active or logged.
Proceed to Test Step 4.
3. Check the Barometric Pressure Sensor Barometric pressure
sensor fault
Result: There is no active -13 code. The fault was
caused by a faulty barometric pressure sensor.
