Sound Signal Circuit between Navigation Receiver Assembly and Stereo Component Tuner Assembly: Procedure
- CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER - STEREO COMPONENT TUNER)
- Disconnect the L38 navigation receiver assembly connector.
- Disconnect the L15 stereo component tuner assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition L38-2 (CDR+) - L15-2 (FRO+) Always Below 1 Ω L38-3 (CDR-) - L15-3 (FRO-) Always Below 1 Ω L38-4 (CDL+) - L15-4 (FLO+) Always Below 1 Ω L38-5 (CDL-) - L15-5 (FLO-) Always Below 1 Ω 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 L38-1 (CSLD) - Body ground Always 10 kΩ or higher TEXT IN ILLUSTRATION*1 Front view of wire harness connector

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- INSPECT STEREO COMPONENT TUNER ASSEMBLY
- Reconnect the L15 stereo component tuner assembly connector.
- Check the waveform according to the conditions in the table below.
