| DESCRIPTION The navigation receiver assembly receives a reverse signal from the park/neutral position switch assembly. WIRING DIAGRAM   CAUTION / NOTICE / HINT NOTICE: Inspect the fuses for circuits related to this system before performing the following procedure. PROCEDURE   | 1.  | CHECK VEHICLE SIGNAL (OPERATION CHECK) |    
	| (a) Enter the "Function Check/Setting I" mode and select "Vehicle Signal" (See page 
	 ). |  |  (b) Check that the display changes between ON and OFF according to the shift lever position. OK:    | Shift Lever Position | Display |   | R | ON |   | Except R | OFF |  HINT: This
 display is updated once per second. As a result, it is normal for the 
display to lag behind the actual shift lever position.   | OK |   |  PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE  |    |   
		| NG |   |   |  |    | 2.  | CHECK NAVIGATION RECEIVER ASSEMBLY |    
	| (a) Disconnect the navigation receiver assembly connector. |  |  (b) Measure the voltage according to the value(s) in the table below. Standard Voltage:   Text in Illustration | Tester Connection | Condition | Specified Condition |   | J135-2 (REV) - Body ground | Ignition switch ON, shift lever in R | 7.5 to 14 V |   | J135-2 (REV) - Body ground | Ignition switch ON, shift lever not in R | Below 1 V |   Result | *a | Front view of wire harness connector (to Navigation Receiver Assembly) |    | Result | Proceed to |   | OK (for Column Shift Type) | A |   | OK (for Floor Shift Type) | B |   | NG | C |    | A |   |  REPLACE NAVIGATION RECEIVER ASSEMBLY  |    | B |   |  REPLACE NAVIGATION RECEIVER ASSEMBLY  |    |   
		| C |   |   |  |    | 3.  | CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER ASSEMBLY - PARK/NEUTRAL POSITION SWITCH ASSEMBLY) |  (a) Disconnect the J135 navigation receiver assembly connector. (b) Disconnect the D35 park/neutral position switch assembly connector. (c) Measure the resistance according to the value(s) in the table below. Standard Resistance:    | Tester Connection | Condition | Specified Condition |   | J135-2 (REV) - D35-1 (RL) | Always | Below 1 Ω |   | J135-2 (REV) - Body ground | Always | 10 kΩ or higher |    | NG |   | REPAIR OR REPLACE HARNESS OR CONNECTOR |    |   
		| OK |   |   |  |    | 4.  | 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:   Text in Illustration | Tester Connection | Switch Condition | Specified Condition |   | D35-2 (RB) - Body ground | Ignition switch ON | 11 to 14 V |    | *a | Front view of wire harness connector (to Park/Neutral Position Switch Assembly) |  HINT: *: Replace park/neutral position switch assembly procedure 
	for A760E:  for A760F:  for AB60E:  for AB60F:     | OK |   | REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY* |    | NG |   | REPAIR OR REPLACE HARNESS OR CONNECTOR |  |
