1996 LAND CRUISER (RM451U)
TROUBLESHOOTING
NOTICE:
When replacing the internal mechanism (computer part) of the audio system, be careful that no part
of your body or clothes comes in contact with the terminals of the leads from the IC, etc. of the re-
placement part (spare part).
HINT:
This inspection procedure is a simple troubleshooting which should be carried\
out on the vehicle during sys-
tem operation and is based on the assumption that the cause of trouble lies\
with the system components
(except for the wires and connectors, etc.).
Always inspect the trouble taking the following items into consideration\
.
Open or short circuit of the wire harness
Connector or terminal connection fault
ProblemNo.
