- CHECK HARNESS AND CONNECTOR (RADIO AND DISPLAY RECEIVER ASSEMBLY - EXTENSION MODULE)
- Disconnect the radio and display receiver assembly connector.
- Disconnect the extension module connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition b3-2 (R+) - b1-13 (R+) Always Below 1 Ω b3-3 (R-) - b1-12 (R-) Always Below 1 Ω b3-4 (L+) - b1-15 (L+) Always Below 1 Ω b3-5 (L-) - b1-14 (L-) Always Below 1 Ω b3-1 (SHD3) - b1-28 (SHD3) Always Below 1 Ω b3-2 (R+) - Body ground Always 10 kΩ or higher b3-3 (R-) - Body ground Always 10 kΩ or higher b3-4 (L+) - Body ground Always 10 kΩ or higher b3-5 (L-) - Body ground Always 10 kΩ or higher b3-1 (SHD3) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
