Perform, then circle when complete OR cross out and give a reason why you did not/could not do it. Screenshot each test and save it in a new wordpad document with the customer’s FIRST and LAST name AND date. IE: “Martin Marquess 1.23.18”
Define the following levels as either (High) (Correct) (Low). Make sure you short stick the oil!
Oil level:___________ Coolant Level:_____________ Oil/Coolant look right? ( Y / N )
Power steering: _________ Brake Fluid: _________ Windshield washer: _________
Battery terminals tight? (Y , N) Clean? (Y , N) Both hold downs present? (Y , N)
Air Filter minder: Present (Y , N), click it (Y , N), check it manually. (Y , N)
Air Filter and Minder (Pass / Fail) Buzz test ( Pass / Fail ) Fuel Pressure: _________
Manually test GPR & All 8 GP’s ( Pass / Fail )
Fuel level:1/8 1/4 3/8 1/2 5/8 3/4 7/8 Full Does fuel look/smell like diesel? ( Y/N )
Load test batteries if concern is present. ( Pass/Fail ) Regardless of outcome, DO NOT let this interfere with you performing the diag, use the battery wagon and move on. Let the office handle the battery issues with the customer.
Record Code #’s and definitions – paste at bottom then clear codes.

Contribution test (EOT MUST BE 170°+) (Pass/Fail) HOT PerDEL numbers: Print screen them here.
First print screen should always be the VIN/MILES.
You should have a print screen of each test and each code definition that is pertinent to issue. You should have 2 print screens for EACH datalogger RECORDING to support your #’s you fill in. You should HIGHLIGHT any PID that is NOT reading correctly. Make sure all of your pids are pulled up on the datalogger BEFORE you conduct tests. Missing information can be the reason for misdiagnosis! Typically you will record the KOEO and KOER startup #’s and then go to power balance quickly. After you get that information you will go back in and get your screenshots and record the numbers manually. This way you do not lose the VITAL cold start information.
