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 L38 navigation receiver assembly connector.
- Disconnect the L110 multi-media interface ECU connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition L38-1 (CSLD) - L110-1 (USD1) Always Below 1 Ω L38-2 (CDR+) - L110-2 (URO+) Always Below 1 Ω L38-3 (CDR-) - L110-3 (URO-) Always Below 1 Ω L38-4 (CDL+) - L110-4 (ULO+) Always Below 1 Ω L38-5 (CDL-) - L110-5 (ULO-) Always Below 1 Ω L38-1 (CSLD) - Body ground Always 10 kΩ or higher L38-2 (CDR+) - Body ground Always 10 kΩ or higher L38-3 (CDR-) - Body ground Always 10 kΩ or higher L38-4 (CDL+) - Body ground Always 10 kΩ or higher L38-5 (CDL-) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 2
