Sound Signal Circuit between Radio Receiver and Multi-display Controller: Wiring Diagram
- CHECK HARNESS AND CONNECTOR (RADIO RECEIVER - MULTI-DISPLAY CONTROLLER)
- Disconnect the connectors from the multi-display controller and radio receiver.
- Measure the resistance according to the value table below.
Standard resistance
RESISTANCE SPECIFIED CONDITIONTester Connection Condition Specified Condition CDR+ - R+ Always Below 1 Ω CDR- - R- Always Below 1 Ω CDL+ - L+ Always Below 1 Ω CDL- - L- Always Below 1 Ω R+ - Body ground Always 10 kΩ or higher R- - Body ground Always 10 kΩ or higher L+ - Body ground Always 10 kΩ or higher L- - Body ground Always 10 kΩ or higher Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step.
- INSPECT MULTI-DISPLAY CONTROLLER
- Reconnect the multi-display controller connector.
- Check the waveform according to the conditions in the table below.
