Sound Signal Circuit between Radio Receiver and Multi-media Interface ECU: Procedure
- CHECK HARNESS AND CONNECTOR (RADIO RECEIVER ASSEMBLY - MULTI-MEDIA INTERFACE ECU)
- Disconnect the radio receiver assembly and multi-media interface ECU connectors.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition E30-1 (USD1) - E16-1 (CSLD) Always Below 1 Ω E30-2 (URO+) - E16-2 (CDR+) Always Below 1 Ω E30-3 (URO-) - E16-3 (CDR-) Always Below 1 Ω E30-4 (ULO+) - E16-4 (CDL+) Always Below 1 Ω E30-5 (ULO-) - E16-5 (CDL-) Always Below 1 Ω E30-1 (USD1) - Body ground Always 10 kΩ or higher E30-2 (URO+) - Body ground Always 10 kΩ or higher E30-3 (URO-) - Body ground Always 10 kΩ or higher E30-4 (ULO+) - Body ground Always 10 kΩ or higher E30-5 (ULO-) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
