INSPECTION PROCEDURE

PROCEDURE

1. CHECK NAVIGATION SYSTEM
(a) Check the navigation system.

Result





B -- CHECK HARNESS AND CONNECTOR (DISPLAY AND NAVIGATION ASSEMBLY - TELEVISION CAMERA)
A -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (MULTI-DISPLAY - TELEVISION CAMERA)
(a) Disconnect the L60 multi-display connector.
(b) Disconnect the S35 television camera connector.




(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. INSPECT MULTI-DISPLAY
(a) Disconnect the S35 television camera connector.




(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:






NG -- REPLACE MULTI-DISPLAY
OK -- Continue to next step.
4. INSPECT TELEVISION CAMERA ASSEMBLY




(a) Reconnect the S35 television camera connector.




(b) Using an oscilloscope, check waveform 1.






OK:
Pulse generation
NG -- REPLACE TELEVISION CAMERA ASSEMBLY
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
