Title: NAVIGATION / MULTI INFO DISPLAY: NAVIGATION ANTENNA: INSPECTION; 2023 - 2025 MY Corolla Corolla Hatchback Corolla HV GR Corolla [11/2022 -        ]

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
