INSPECTION
PROCEDURE
1. INSPECT NAVIGATION ANTENNA ASSEMBLY (w/o Manual (SOS) Switch)
(a) Check that the navigation antenna assembly cable is properly installed and does not have any sharp bends, pinching or loose connections.
(b) Current consumption check:
| (1) Measure the current consumption according to the value(s) in the table below. Standard Current: | Tester Connection | Condition | Specified Condition | | 3 (core) - 3a (shield) | 4.2 to 5 V applied between terminals 3 and 3a | 10 to 30 mA | NOTICE: Do not apply 6 V or more between terminals 3 and 3a. HINT: If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series. |  | | *a | Component without harness connected (Navigation Antenna Assembly) | | *b | Voltage Applied between Terminals | | |
2. INSPECT NAVIGATION ANTENNA ASSEMBLY (w/ Manual (SOS) Switch)
(a) Check that the navigation antenna assembly cable is properly installed and does not have any sharp bends, pinching or loose connections.
(b) Current consumption check: (GPS)
| (1) Measure the current consumption according to the value(s) in the table below. Standard Current: | Tester Connection | Condition | Specified Condition | | 3 (core) - 3a (shield) | 4.2 to 5 V applied between terminals 3 and 3a | 10 to 30 mA | NOTICE: Do not apply 6 V or more between terminals 3 and 3a. HINT: If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series. |  | | *a | Component without harness connected (Navigation Antenna Assembly) | | *b | Voltage Applied between Terminals | | |
(c) Resistance check: (Telephone Sub)
| (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: | Tester Connection | Condition | Specified Condition | | 4 (core) - 4a (shield) | Always | 9 to 11 kΩ | |  | | *a | Component without harness connected (Navigation Antenna Assembly) | | |
