INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (REVERSE SIGNAL)

(a) Disconnect the radio and display receiver assembly connector.

(b) Measure the voltage according to the value(s) in the table below.

Standard Voltage:





NG -- CHECK HARNESS AND CONNECTOR (RADIO AND DISPLAY RECEIVER ASSEMBLY - PARK/NEUTRAL POSITION SWITCH ASSEMBLY)

OK -- PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE Problem Symptoms Table

2. CHECK HARNESS AND CONNECTOR (RADIO AND DISPLAY RECEIVER ASSEMBLY - PARK/NEUTRAL POSITION SWITCH ASSEMBLY)

(a) Disconnect the radio and display receiver assembly connector.

(b) Disconnect the park/neutral position switch assembly connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH ASSEMBLY - BATTERY)

(a) Disconnect the park/neutral position switch assembly connector.

(b) Measure the voltage according to the value(s) in the table below.

Standard Voltage:





(c) Proceed to the next step based on the check result.

Result:





B -- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY (for U660E)

C -- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY (for U760E) Removal

A -- REPAIR OR REPLACE HARNESS OR CONNECTOR
