C: INSPECTION
NOTE:
• For self diagnosis of the audio system, there is a communications check (communication condition be-
tween the audio and the control panel) and a switch check. Perform a communications check first and make
sure it is operating normally before proceeding to the inspection of switches.
• Complete operations from when the self diagnosis mode of step 1 operates and the buzzer sounds, until
you press the preset 1 switch in step 4, within 15 seconds. If 15 seconds or more pass, a communications
error will be displayed.
• During the diagnosis, do not press the POWER (8), FM/AM (12), CD (11), AUX (13) or SAT (18) switches.
Pressing these switches will disengage the self diagnosis mode. For the CD and AUX switch, the self diag-
nosis mode will be disengaged if the disc load and unit are connected.
