INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (REVERSE SIGNAL)

(a) Disconnect the E5 navigation receiver assembly.

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

Standard Voltage:





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

Result:





C -- CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER ASSEMBLY - PARK/NEUTRAL POSITION SWITCH)

B -- CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER ASSEMBLY - PARK/NEUTRAL POSITION SWITCH)

A -- REPLACE NAVIGATION RECEIVER ASSEMBLY Removal

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

(a) Disconnect the E5 navigation receiver assembly connector and B5 park/neutral position switch assembly connector.

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

Standard Resistance:





Proceed to the next step based on the check result.

Result:





C -- REPAIR OR REPLACE HARNESS OR CONNECTOR

B -- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY (for U151E) Removal

A -- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY (for U151F)

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

(a) Disconnect the E5 navigation receiver assembly connector and B5 park/neutral position switch assembly connector.

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

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

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