INSPECTION PROCEDURE

PROCEDURE

1. CHECK WIRE HARNESS (DOOR OSCILLATOR - ANTENNA)

(a) Remove the outside handle.





(b) Disconnect the antenna and door oscillator connectors.





(c) Measure the resistance between the oscillator and the antenna to check for an open circuit in the wire harness.

Resistance:

Below 1 Ohms

(d) Measure the resistance between the oscillator and the antenna to check for a short circuit in the wire harness.

Resistance:

10 kOhms or higher

HINT
Refer to the wiring diagram for connection of each terminal.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
