To enter diagnostic mode, proceed as follows:

1. Turn ignition "ON." Engine can be either OFF or RUNNING.

For cars equipped with the Digital Instrument Panel Display (Digital IPC):
2. Simultaneously press the "OFF and "WARMER" (red) buttons on climate control center (CCC) until all display segments (IPC and CCP) are illuminated

For cars equipped with the Analog Instrument Panel Display (Analog IPC):
3. Simultaneously press on the Climate Control Panel (CCP) the "OFF" and "PASS WARMER" (up arrow) buttons.

After the segment display test, the driver message center displays all set DTC, current and history, in the following order:


The RSS, CCP, MSM, MMM and PHN DTC appear only on vehicles equipped with these options. Press the FAN DOWN button in order to bypass the DTC display.

On the OBD II cars, the prefixes you'll see are: "IP" for the IPC instrument panel; "AC" for air conditioning module; "TC" for traction control; "RS" for the road suspension system; "SD" for the air bags; "PZ" for the body control module; "CC" for the cell phone; "RF" for the integrated radio system.


To exit the diagnostic mode anytime during the test, depress the "ECON" or "DEFOG" button, or turn the ignition switch "OFF." .

You don't need a scan tool for these cars,as it is all built in.

Go to the following website for a list of trouble codes.

Add a comment to your post if you require any further assistance.

Hope this helps.

Door ajar alarm is on constantly when dash lights dimmer is on. Turn to off and alarm stops

Your best bet would be to take your vehicle to a qualified repair shop that's good with automotive electrical problems . Checking for DTC'S diagnostic trouble codes would be a good first step . The GEM - generic electronic module is fords BCM - body control module . There is a door ajar switch located in each door , when a door is open the GEM module detects this an turns on the alarm (chime ,bing or what ever noise yours makes ) Also turns on the little car symbol showing a particular door as being open . You could have a GEM module problem , Or you could go to Find wiring diagrams an try to trouble shoot this yourself. Go on youtube an watch videos on basic electrical trouble shooting , how to read a wiring diagram . Plus check out some repair videos door ajar switch problems !

in order to recharge the ac you first must clear the trouble code for the ac off warning. when you get this warning the computer shuts down the compressor to keep it from running without the lubricant that is in the freon. clear the trouble code and the compressor will run and you can recharge the ac.

"SRS-AIRBAG SERVICE" fault message

Here's a quick check list for most common cost of SRS / Air bag problem.

Dirty contacts on driver and passenger seat belt buckles

Dirty contacts on seat belt connectors (under seats)

Dirty contacts on driver and passenger sides weight sensors (under seat)

Seat covers

Weight on passenger seat
(Example: grocery package trigger SRS / Air Bag light on the way home.)

I recommend you to pass an vacuum over the contacts and use CRC electronic parts cleaner to rule out connectivity problem.

I DO NOT recommend disconnecting the negative battery connector to clean the code(s).

Without the code(s) the dealer will takes "BILLABLE" time to reproduce the problem.
