Typical Enabling Conditions
Always On
Monitor Sequence
None
Execution Frequency
Continuous When Enabling Conditions Met
Typical Duration
2 Seconds
Dash Lamps
MIL, CEL, SEL
Engine Reaction
Derate 25%
Verification
Run Engine Between 1200 to 1800 rpm With a Load Less Than 10%
Check as follows:
1. Connect DiagnosticLink ®.
2. Turn the ignition ON (key ON, engine OFF).
3. Check for other fault codes. Are fault codes SPN 3609/FMI 3 or FMI 4 present?
a. Yes; diagnose the other fault codes first.
b. No; Go to step 4.
4. Using DiagnosticLink go to Service Routines > SCR and DPF voltages.
5. Monitor the DOC inlet pressure sensor voltage, pin 87. Is the voltage between 0.44 and 0.56 volts?
a. Yes; Go to step 6.
b. No; replace the DOC inlet pressure sensor. Refer to section "Removal of the GHG14 Diesel Oxidation Catalyst
Inlet Pressure Sensor". Verify repair.
6. Monitor the DPF outlet pressure sensor voltage, pin 72. Is the voltage between 0.44 and 0.56 volts?
a. Yes; Go to step 7.
b. No; replace the DPF outlet pressure sensor. Refer to section "Removal of the GHG14 Diesel Particulate Filter
Outlet Pressure Sensor". Verify repair.
7. Perform the Low temperature ATD routine. Refer to section "GHG14 Perform Performance Check - Low Temperature
ATD".
8. Monitor the DOC inlet temperature and the DOC outlet temperature readings. Does the DOC outlet temperature sensor
reading follow the DOC inlet temperature sensor reading?
a. Yes; replace the DPF due to a restriction. Refer to section "Removal of the GHG14 Diesel Particulate Filter".
Verify repair.
b. No; replace the DOC due to a restriction. Verify repair.
