INSPECTION PROCEDURE

PROCEDURE

1. INSPECT NAVIGATION RECEIVER ASSEMBLY




(a) Disconnect the navigation receiver assembly connector F13.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:






OK -- REPLACE NAVIGATION RECEIVER ASSEMBLY
NG -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR




(a) Disconnect the navigation receiver assembly connector F13 and park/neutral position switch connector C1 or back-up light switch connector C28.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






*1: 2AZ-FE, A/T
*2: 2GR-FE, A/T
*3: M/T
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. CHECK VEHICLE TYPE
(a) Choose type to be inspected.
Result:






B -- INSPECT BACK-UP LIGHT SWITCH
A -- Continue to next step.
4. INSPECT PARK/NEUTRAL POSITION SWITCH




(a) Disconnect the park/neutral position switch connector C1.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPLACE PARK/NEUTRAL POSITION SWITCH
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR
5. INSPECT BACK-UP LIGHT SWITCH




(a) Disconnect the buck-up light switch connector C28.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPLACE BACK-UP LIGHT SWITCH
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR
