1. Check the car, confirm the fault. Convert CD and broadcast audio output as usual, consult GTR no relevant troubleshooting information (the car entertainment system not involve the relevant content of K064K), connect with JLR SDD diagnostic tool to read DTC, in FCDIM has U0191-00: Lostcommunication with the television, fault tracking tip 100%. According DA-VINA 2534 SAE J2534 diagnostic guidelines refresh Existing Module: television Module, the fault persists, refresh Existing Module FCDIM failure remains.
2. According to circuit diagram, check TV Module CJB F68 # 10A fuse normal no fusible phenomenon, measure TV module C4ME33A/1 pin voltage:11.68V, C4ME33A/2 pin grounding point normal, check ground terminal fixed point G4D 172AR without loosening and corrosion phenomenon. Measure FCDIM No. CJBF69 15A fuse normal no fusible phenomenon, measure FCDIM No. C2MC02A/8 pin and C2MC02A/16 pin voltage: 11.68V in normal range. Measure C2MC02A/2 pin Alp and C2MC02A/13 pin grounding point normal. Check the ground terminal fixed point: G2D 185AL no looseness and corrosion. Watch the MOST network cycle normal.
3. Recalling the customer description, before the failure not appear, the customer to shop for navigation inspection, then cut off install the GPS system host power supply, the fault persists. Re-view X351 entertainment system information: TV Module is an audio and video terminal signal output and feedback, and whether to perform actions and receive audio and video signals depend FCDIM front display screen, integrated JLR SDD VCM prompt FCDIM Module fault tracing tips 100%.
Troubleshooting: swap FCDIM with the new car, test, fault ruled out.
