Cause:
North America
Intermittent No Crank. Vehicle Powers Up Normally.
Oxidized B+ Nut or Stud On The Starter Solenoid.
If a vehicle presents with an intermittent power up but no crank concern verify the BCM Power Mode Data shows Crank, The
ECM Electrical Data shows active Crank Request and Crank Relay Command. If data is correct, check for power at the B+
terminal at the starter. If present, inspect the B+ stud on the starter for oxidation as shown below.
If it's oxidized as shown in the photos, you should replace the nut and clean the stud terminals and re-check starter
function. If this corrects the concern, release the truck. If not, continue with starter diagnosis / replacement.
