IMAGE NOT OUTPUT IN ALL MODES [ENTERTAINMENT SYSTEM [WITH CENTER DISPLAY]]

id0903l8060000

Description	IMAGE NOT OUTPUT IN ALL MODES
Description	Image is not output in center display even if any mode is selected
Possible Causes	• Center display setting is off • Center display B+ power supply circuit malfunction (DTC B108E:1C is stored in connectivity master unit (CMU)) • Center display ACC power supply circuit malfunction (DTC B108E:1C is stored in connectivity master unit (CMU)) • Connectivity master unit (CMU) B+ power supply circuit malfunction (DTC U3003:16 is stored in connectivity master unit (CMU)) • Connectivity master unit (CMU) ACC power supply circuit malfunction(DTC U3003:16 is stored in connectivity master unit (CMU)) • Open or short circuit in wiring harness between the following terminals: (B108E:06 is stored in connectivity master unit (CMU)) ? Connectivity master unit (CMU) terminal 3B and center display terminal 2B ? Connectivity master unit (CMU) terminal 3D and center display terminal 2D • Connector poor contact or terminal damage • Open circuit in wiring harness between center display terminal 1B and body ground • Open circuit in wiring harness between connectivity master unit (CMU) terminal 2L, 2D, 2C and body ground • Center display malfunction • Connectivity master unit (CMU) malfunction

Diagnostic Procedure

Step	Inspection		Action
1	VERIFY PERSONALIZATION FEATURES SETTING • Operate the commander switch. (See SECURITY AND LOCKS PERSONALIZATION FEATURES SETTING PROCEDURE.) • Does the center display display?	Yes	Cause is that the center display setting was off. Explain to the customer that the screen setting was off.
1		No	Go to the next step.
2	VERIFY CONNECTIVITY MASTER UNIT (CMU) DTC • Retrieve any DTCs using the M-MDS. (See DTC INSPECTION [CONNECTIVITY MASTER UNIT].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [CONNECTIVITY MASTER UNIT].)
2		No	Go to the next step.
3	INSPECT CENTER DISPLAY CONNECTOR • Switch the ignition off. • Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) • Disconnect the center display connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Go to the next step.
3		No	Repair or replace the connector, then go to Step 8.
4	INSPECT CONNECTIVITY MASTER UNIT (CMU) CONNECTOR • Disconnect the connectivity master unit (CMU) connector. • Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Go to the next step.
4		No	Repair or replace the connector, then go to Step 8.
5	VERIFY IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN CENTER DISPLAY AND BODY GROUND • Verify that the center display connector is disconnected. • Inspect the wiring harness for continuity between center display terminal 1B and body ground (vehicle wiring harness side). • Is there continuity?	Yes	Go to the next step.
5		No	• Refer to the wiring diagram and verify if there is a common connector between center display terminal 1B and body ground. If there is a common connector: ? Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for an open circuit to determine the malfunctioning location. ? Repair or replace the malfunctioning location. If there is no common connector: ? Repair or replace the wiring harness which has an open circuit. • Go to Step 8.
6	VERIFY IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN CONNECTIVITY MASTER UNIT (CMU) AND BODY GROUND • Verify that the connectivity master unit (CMU) connector is disconnected. • Inspect the wiring harness for continuity between following connectivity master unit (CMU) terminals and body ground (vehicle wiring harness side). ? Connectivity master unit (CMU) terminal 2L ? Connectivity master unit (CMU) terminal 2D ? Connectivity master unit (CMU) terminal 2C • Is there continuity?	Yes	Go to the next step.
6		No	• Refer to the wiring diagram and verify if there is a common connector between the following terminals. ? Connectivity master unit (CMU) terminal 2L and body ground ? Connectivity master unit (CMU) terminal 2D and body ground ? Connectivity master unit (CMU) terminal 2C and body ground If there is a common connector: ? Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for an open circuit to determine the malfunctioning location. ? Repair or replace the malfunctioning location. If there is no common connector: ? Repair or replace the wiring harness which has an open circuit. • Go to Step 8.
7	VERIFY IF MALFUNCTION CAUSE IS CENTER DISPLAY • Replace the center display. (See CENTER DISPLAY REMOVAL/INSTALLATION.) • Connect all the connectors. • Reconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.) • Switch the ignition to ACC or ON (engine off or on). • Is image output in the center display?	Yes	Go to the next step.
7		No	Replace the Connectivity master unit (CMU), then go to the next step. (See CONNECTIVITY MASTER UNIT (CMU) REMOVAL/INSTALLATION.)
8	VERIFY IF MALFUNCTION CAUSE IS CORRECTED • Switch the ignition to ACC or ON (engine off or on). • Select each mode by operating the center display or the commander switch. • Is image in each mode output?	Yes	Troubleshooting completed (explain the contents of the servicing to the customer).
8		No	Verify the malfunction symptom in the symptom troubleshooting chart and perform the other applicable malfunction diagnosis. (See SYMPTOM TROUBLESHOOTING [ENTERTAINMENT SYSTEM [WITH CENTER DISPLAY]].)
