- CHECK HARNESS AND CONNECTOR
- Disconnect the radio receiver assembly and stereo component amplifier assembly connectors.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition E31-19 (L-) - E20-2 (L-) Always Below 1 Ω E31-9 (L+) - E20-3 (L+) Always Below 1 Ω E31-18 (R-) - E20-4 (R-) Always Below 1 Ω E31-8 (R+) - E20-5 (R+) Always Below 1 Ω E31-10 (SLD) - Body ground Always 10 kΩ or higher E31-19 (L-) - Body ground Always 10 kΩ or higher E31-9 (L+) - Body ground Always 10 kΩ or higher E31-18 (R-) - Body ground Always 10 kΩ or higher E31-8 (R+) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
