DIAGNOSTIC STEPS
WARNING
To prevent personal injury or death, shift transmission to park or neutral, set parking brake, and block wheels before doing diagnostic or service
procedures.
WARNING
To prevent personal injury or death, make sure the engine has cooled before removing components.
WARNING
To prevent personal injury or death, do not let engine fluids stay on your skin. Clean skin and nails using hand cleaner and wash with soap and
water. Wash or discard clothing and rags contaminated with engine fluids.
WARNING
To prevent personal injury or death, read all safety instructions in the "Safety Information" section of the diagnostic manuals.
WARNING
These diagnostics require running the engine with cover(s) removed exposing moving components. Glasses are required due to oil splash and
do not touch moving components.
Step Action
Generate a Health Report
1
Was the health report successful?
Step Action
2
Yes. Step 2
No. Resolve, Step 2
Decision
Verify calibration.
Yes. Step 3
Is the calibration up-to-date?
No. Update Calibration. Step 3
Step Action
3
Decision
Perform visual checks per Diagnostic Manual and/or Performance Diagnostic
sheet.
Decision
Yes. Correct the issue(s). If the oil level is
over full, drain it to a proper level and take
a sample for analysis.
1. Inspect Fuel System to Verify Fuel Level
https://evalue.internationaldelivers.com/service_kb/DocTool/ArticleViewer.aspx?ControlID... 6/1/2015
IK1201259 MaxxForce 7 Fuel Dilution Diagnostics
2. Inspect Engine Oil Level
3. Inspect Coolant Recovery Bottle for Coolant Level
4. Inspect Electrical Group for Poor or Loose Connections
5. Inspect Air Filter Minder
6. Inspect Exhaust System
Page 4 of 9
Otherwise continue to Step 4.
No. If the oil level is normal, has no signs
of dilution, and the complaint is low
pressure, see IK1200744
Any issues noted?
Step Action
Inspect engine operation.
4
Does the engine run rough with a corrected oil level?
Step Action
Yes. See IK1201222
No. Step 5
Decision
Disclose oil service habits from the customer and compare to the Operator
Manual service recommendation.
1. Current Oil life is within limits and
customer is following interval
requirements.
20072009 MaxxForce 7: 10,000 Miles or 350 hours, which ever comes first.
Step 6
2. Current Oil life is within limits but
the customer is not following interval
requirements.
2010-2013 MaxxForce 7:
Fuel Economy is less than 7 MPG: Every 7,000 miles
Fuel Economy is greater than 7 MPG but less than 11 MPG:
Miles = (2000 X MPG) - 7000
Ex. MPG = 8.2
2000(8.2) - 7000 = 9,400 miles
5
Decision
Fuel Economy > 11MPG: Every 15,000 Miles
Inform the customer of the proper service
interval for their application and continue
to
Step 6
3. Current Oil life is beyond the
service limits and the customer is
not following interval requirements.
Get customer approval to change the oil
out of warranty expense. Return the truck
to the customer and monitor the oil level.
If the oil level rises in an unreasonable
amount, the truck must be diagnosed
