- CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER ASSEMBLY - STEREO COMPONENT AMPLIFIER ASSEMBLY)
- Disconnect the L149 navigation receiver assembly connector.
- Disconnect the L31 stereo component amplifier assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition L31-5 (R+) - L149-1 (FR+) Always Below 1 Ω L31-4 (R-) - L149-5 (FR-) Always Below 1 Ω L31-3 (L+) - L149-2 (FL+) Always Below 1 Ω L31-2 (L-) - L149-6 (FL-) Always Below 1 Ω L31-6 (SLD) - Body ground Always 10 kΩ or higher L31-5 (R+) - Body ground Always 10 kΩ or higher L31-4 (R-) - Body ground Always 10 kΩ or higher L31-3 (L+) - Body ground Always 10 kΩ or higher L31-2 (L-) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → Refer to 2
