NOTE: The following procedure should only be used once the problem has definitely been determined to be Intermittent. Otherwise, refer to Section 5 of the 3406C Electronic Troubleshooting Guide (Form No. SENR5503) to isolate an Active problem.
Complete Steps 1 and 2
Interview the driver using the Driver Questionnaire.
Use the Diagnosis and Action column.
Complete Steps 3 Through 17 if monitoring the ECAP did not reveal the problem.
Each step will eliminate one subsystem (complete all steps).
Take the truck for a test drive after each step(s) to determine which step eliminates the problem.
