P-103 Intermittent Engine Speed or Speed Burps
Usage:
NOTE: The following procedure should only be used once the problem has definitely been determined to be Intermittent. Otherwise, refer to Section 2 of the 3406B Electronic Troubleshooting Guide, SENR3479, to isolate an Active problem.
Complete Steps 1 through 3
Interview the driver using the Driver Questionnaire.
Use the "Diagnosis and Action" column.
Complete Steps 4 Through 16 If Monitoring The ECAP Did Not Reveal The Problem
Each step will eliminate one subsystem.
Take the truck for a test drive after each step(s) to determine which step eliminates the problem.
If the problem is gone, work backwards using the "Diagnosis/Action" column to determine which step has eliminated the problem.
