Pinpoint Test K: An Individual Front Display Interface Module (FDIM) Display Is Inoperative
Normal Operation
The Front Display Interface Module (FDIM) display provides information based on the video signal from the Audio Control Module (ACM). In addition to the information that the ACM controls for the navigation and audio system, the ACM receives inputs via the Medium Speed Controller Area Network (MS-CAN) from the following modules:
- Accessory Protocol Interface Module (APIM): SYNC system information
- HVAC module: climate control system information
- Rear Entertainment Module (RETM): family entertainment system information (if equipped)
If the ACM loses the signal from any of these modules, only that specific display becomes inoperative.
This pinpoint test is intended to diagnose the following:
- Communication network concern
- FDIM
- ACM
PINPOINT TEST K: AN INDIVIDUAL FDIM DISPLAY IS INOPERATIVE
-------------------------------------------------
K1 OBSERVE THE FDIM DISPLAY
- Turn the audio system on and observe the FDIM screen.
- Is the FDIM display completely inoperative?
Yes
GO to Pinpoint Test I. Pinpoint Test I: The Front Display Interface Module (FDIM) Is Completely Inoperative
No
GO to K2.
-------------------------------------------------
K2 CHECK THE FDIM DISPLAY SEGMENTS
- Carry out the Audio Display Test. Refer to Audio Control Module (ACM) Self-Diagnostic Mode Audio Control Module (ACM) Self-Diagnostic Mode.
- Do all of the FDIM segments illuminate?
Yes
GO to K3.
No
GO to K5.
-------------------------------------------------
K3 OBSERVE THE SPECIFIC INOPERATIVE DISPLAY
- Observe the inoperative FDIM display while carrying out the indicated diagnostic method as follows:
- Does the suspect display confirm the expected results?
Yes
The system is operating correctly at this time. INFORM the customer on the operation of the FDIM displays.
No
GO to K4.
-------------------------------------------------
K4 CHECK FOR LOST COMMUNICATION DTCs
- Ignition ON.
- Clear continuous DTCs from all modules.
- Ignition OFF.
- Ignition ON.
- Wait at least 10 seconds.
- Retrieve all continuous DTCs from all modules.
- Is DTC U0164, U0164:00, U0184, U0184:00, U0196 or U0196:00 (if equipped with the family entertainment system), or U0197 or U0197:00 present in any module?
Yes
REFER to DTC Charts. Diagnostic Trouble Code Tests and Associated Procedures
No
INSTALL a new FDIM. REFER to Front Display Interface Module (FDIM) Front Display Interface Module (FDIM). TEST the system for normal operation. If the concern is still present, GO to K5.
-------------------------------------------------
K5 CHECK FOR CORRECT ACM OPERATION
- Ignition OFF.
- Disconnect all the ACM connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the ACM connectors and make sure they seat correctly.
- Operate the system and determine if the concern is still present.
- Is the concern still present?
Yes
INSTALL a new ACM. REFER to Audio Control Module (ACM) Audio Control Module (ACM). TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
