PROCEDURE

1. INSPECT NAVIGATION ANTENNA ASSEMBLY

(a) 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.

If the result is not as specified, replace the navigation antenna assembly.

Component without harness connected

(Navigation Antenna Assembly)

Voltage Applied between Terminals

(b) 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	9.0 to 11 kΩ

If the result is not as specified, replace the navigation antenna assembly.
