DIAGNOSIS NUMBER CHARTNJEL0603S03
Diagnosis No. Possible causes
Diagnosis 1 Control unit (AV and NAVI C/U) is malfunctioning.
Diagnosis 2 AV and NAVI C/U determines that no map DVD-ROM is inserted.
Diagnosis 3If “DVD-ROM is malfunctioning. Check disc.” is displayed:
1. Remove inserted map DVD-ROM and check that it is correct special DVD-ROM.
2. Check that there is no dirt, damage, or warping on removed DVD-ROM.
3. If above checks reveal nothing unusual, insert another map DVD-ROM withsame contents. Then check
whether same diagnosis result is obtained when “Self-diagnosis” is performed. If result is same, AV and NAVI
C/U is malfunctioning. If not same, map DVD-ROM should be replaced.
Diagnosis 4“DVD-ROM or DVD-ROM driver in C/U is malfunctioning. Follow maintenance procedures to diagnose.” is dis-
played: Perform check as described in Diagnosis 3.
Diagnosis 5Display power supply or ground line
AV communication line between Display and multifunction switch
Diagnosis 6 Audio unit power supply or ground line
Diagnosis 7 CD auto changer power supply and ground circuit, Communication line between CD auto changer and audio unit
Diagnosis 8GPS antenna system
1. Visually check for open circuit in GPS antenna coaxial cable.
2. Disconnect GPS antenna connector and check AV and NAVI C/U outputs approx. 5V. If there is no voltage,
AV and NAVI C/U is malfunctioning. If there is, replace GPS antenna. If connection is inoperative after per-
forming self-diagnosis again, AV and NAVI C/U is malfunctioning.
