3. NOTE: Not all passenger junction box (PJB) variants support the speed control system.
NOTE: If the PJB is configured for speed control disable, speed control operation is not transmitted, no Diagnostic Trouble Codes (DTCs) are generated.
If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the cause is not visually evident, verify the symptom and refer to the diagnostic tab within the Ford approved diagnostic tool.
