The sub-code will be indicated by its physical address. For the component list, refer to Diagnosis Display Detailed Description in the System Description. Refer to «SYSTEM DESCRIPTION»(ref-385262-S28647305572011021400000) . NEXT: Go to next step
  2. CHECK POWER SOURCE CIRCUIT OF COMPONENT SHOWN BY SUB-CODE Inspect the power source circuit of the component shown by the sub-code. COMPONENT TABLE Display Proceed to Radio receiver (190) Radio receiver power source circuit. Refer to «Radio Receiver Power Source Circuit»(ref-385265-S21688277082011021400000) Stereo component amplifier (440) Stereo component amplifier power source circuit. Refer to «Stereo Component Amplifier Power Source Circuit»(ref-385265-S06475065432011021400000) Multi-display (110)*1 Multi-display power source circuit. Refer to «Multi-display Power Source Circuit»(ref-385265-S19327313492011021400000) Display and navigation module display (118)*2 Display and navigation assembly power source circuit. Refer to «Display and Navigation Assembly Power Source Circuit»(ref-385266-S09151538372011021400000) Parking assist ECU (1AC)*3 Parking assist ECU power source circuit. Refer to «ECU Power Source Circuit»(ref-385270-S04161577302011021400000) Stereo component tuner (1F1)*4 Satellite radio tuner power source circuit. Refer to «Satellite Radio Tuner Power Source Circuit»(ref-385265-S41934865682011021400000) If the power source circuit is operating normally, proceed to the next step. *1: w/ Navigation System *2: w/o Navigation System *3: w/ Wide View Front and Side Monitor System *4: w/ SDARS System NEXT: Go to next step
  3. INSPECT RADIO RECEIVER ASSEMBLY Disconnect the F1, F23 and F24 receiver connectors. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition F1-5 (ATX+) - F1-15 (ATX-) Always 60 to 80 ohms F23-9 (TX+) - F23-10 (TX-) Always 60 to 80 ohms F24-9 (TXM+) - F24-10 (TXM-) Always 60 to 80 ohms NG --> See step 6 OK: Go to next step
  4. CHECK HARNESS AND CONNECTOR (TELEVISION DISPLAY - COMPONENT SHOWN BY SUB-CODE) HINT: Start the check from the circuit that is near the component shown by the sub-code first. For details of the connectors, refer to Terminals of ECU. Refer to «TERMINALS OF ECU»(ref-385262-S02192398962011021400000) . Referring to the AVC-LAN wiring diagram, check the AVC-LAN circuit between the television display and the component shown by the sub-code. Disconnect all connectors between the television display and the component shown by the sub-code. Check for an open or short in the AVC-LAN circuit between the television display and the component shown by the sub-code. OK There is no open or short circuit. NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
  5. REPLACE COMPONENT SHOWN BY SUB-CODE Replace the component shown by the sub-code with a normal one and check if the same problem occurs again. OK Same problem does not occur. NG --> See step 7 OK --> END
  6. REPLACE RADIO RECEIVER ASSEMBLY. Refer to «REMOVAL»(ref-385264-S14664248812011021400000)
  7. REPLACE TELEVISION DISPLAY ASSEMBLY. Refer to «REMOVAL»(ref-385264-S16985882572011021400000)
