Reverse Signal Circuit: Procedure
- CHECK NAVIGATION RECEIVER ASSEMBLY (REVERSE SIGNAL INPUT)
- Disconnect the E39 connector from the navigation receiver assembly.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition E39-5 (REV) - Body ground Ignition switch ON, shift lever in R 7 V or higher
NG → See step 3
OK → See step 2
- PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE. Refer to PROBLEM SYMPTOMS TABLE .
- CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER - PARK/NEUTRAL POSITION SWITCH)
- Disconnect the E39 connector from the navigation receiver assembly.
- Disconnect the B13 connector from the park/neutral position switch assembly.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition E39-5 (REV) - B13-2 (RL) Always Below 1 Ω E39-5 (REV) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
- Disconnect the B13 connector from the park/neutral position switch assembly.
- Measure the resistance according to the value(s) in the table below.
