Operation CHARM: Car repair manuals for everyone.

Initial Inspection

NOTE:
^ Dropped calls,bad connections, noisy audio, problems in certain geographic areas, problems at the edge of coverage areas, same time/place each day or under bridges, tunnels, etc., usually indicate a system or cellular phone carrier concern and are not the fault of the phone itself.
^ A customer initial call must be made from their home coverage area for proper activation of the Ford Cellular System. There might be a slight delay in activation after leaving the dealership from initial delivery.
^ The audio system does not operate when the portable cellular phone is in use because the audio-mute feature will mute the audio system when a call is placed or received.

If there is a concern making calls on the portable cellular phone while it is connected to the vehicle, check the following:
1. Make sure the portable cellular phone is turned ON. With the power button ON, the system should be on while the ignition switch is in ACC or RUN.
2. Make sure the customer is calling within the coverage area. No SVC will appear in the display if the customer is calling from outside the coverage area.
3. Check to see if the Roam indicator is on. If so, follow the roaming instructions in the User's Guide.
4. Check to see if the display reads Locked. If so, press Clr and enter the customer three-digit unlock code.
5. Make sure the portable cellular phone is securely connected to the coil cord and seated in the holder.
6. Check the coil cord connections in the console.
7. Check the portable cellular phone antenna and Portable Support Electronics (PSE) module connections.
8. Check the portable cellular phone system registration. Also, check to make sure that the portable cellular phone is correctly programmed. Incorrect programming can result in single system scanning, loss of speed dialing, loss of hands-free audio, loss of auto redial, loss of dial tone multi-frequency tones, and the loss of other keypad/portable cellular phone functions.
9. Check the customer account status with the cellular phone carrier.

If the customer concern is still present, follow these steps to diagnose the concern:

10. Verify the customer concern by operating the portable cellular phone system to duplicate the condition.
11. Inspect to determine if one of the mechanical or electrical concerns apply.







12. If inspection reveals obvious concerns which can be readily identified, repair as necessary.
13. If the cause of the fault is not visually evident, proceed to diagnose the portable cellular phone system/Audio Control Module (ACM) by:
^ Entering the scan tool diagnostics or
^ Entering ACM Self-Diagnostic Mode.
