Sound Signal Circuit between Navigation Receiver Assembly and Multi-media Interface ECU: Procedure
- CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER ASSEMBLY - MULTI-MEDIA INTERFACE ECU)
- Disconnect the E15 navigation receiver assembly connector.
- Disconnect the E30 multi-media interface ECU connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition E15-1 (CSLD) - E30-1 (USD1) Always Below 1 Ω E15-2 (CDR+) - E30-2 (URO+) Always Below 1 Ω E15-3 (CDR-) - E30-3 (URO-) Always Below 1 Ω E15-4 (CDL+) - E30-4 (ULO+) Always Below 1 Ω E15-5 (CDL-) - E30-5 (ULO-) Always Below 1 Ω E15-2 (CDR+) - Body ground Always 10 kΩ or higher E15-3 (CDR-) - Body ground Always 10 kΩ or higher E15-4 (CDL+) - Body ground Always 10 kΩ or higher E15-5 (CDL-) - Body ground Always 10 kΩ or higher E15-1 (CSLD) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 2
