NOTE: After inspecting intermediate connector C-41, IOD or 
storage connector A-54X and junction block connectors D-06 
and D-08, inspect the wire. If intermediate connector C-41, IOD 
or storage connector A-54X and junction block connectors 
D-06 and D-08 are damaged, repair or replace them. Refer to 
GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Are the harness wires between radio and CD player 

connector C-62 (terminal No.10) and ignition switch 
(ACC) in good condition?
YES : 
There is no action to be taken.
NO :  Repair them. If the power switch is turned on, the 

radio and CD player should operate normally.
