DIAGNOSTIC PROCEDURE

Step Inspection Action
1 VERIFY RELATED STORED DTC 
 Yes Go to the applicable DTC inspection.
(See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM] ).
No Go to the next step.
2 INSPECT NEUTRAL SWITCH CONNECTOR 
  • Switch the ignition to off.
  • Disconnect the negative battery cable.
  • Disconnect the neutral switch connector.
  • Inspect the connector and terminals (corrosion, damage, pin disconnection).
  • Is there any malfunction?
 Yes Repair or replace the connector or terminals, then go to Step 9.
No Go to the next step.
3 INSPECT NEUTRAL SWITCH GROUND CIRCUIT FOR OPEN CIRCUIT 
  • Neutral switch connector is disconnected.
  • Inspect for continuity between the following terminal (wiring harness-side) and body ground:
    • Neutral switch terminal B
  • Is there continuity?
 Yes Go to the next step.
No Repair or replace the wiring harness for a possible open circuit, then go to Step 9.
4 INSPECT NEUTRAL SWITCH 
 Yes Replace the neutral switch, then go to Step 9.
(See NEUTRAL SWITCH REMOVAL/INSTALLATION [G35M-R] ).
(See NEUTRAL SWITCH REMOVAL/INSTALLATION [G66M-R] ).
(See NEUTRAL SWITCH REMOVAL/INSTALLATION [A26M-R] ).
No Go to the next step.
5 INSPECT KEYLESS CONTROL MODULE CONNECTOR 
  • Disconnect the keyless control module connector.
  • Inspect the connector and terminals (corrosion, damage, pin disconnection).
  • Is there any malfunction?
 Yes Repair or replace the connector or terminals, then go to Step 9.
No Go to the next step.
6 INSPECT NEUTRAL SWITCH POWER SUPPLY CIRCUIT FOR SHORT TO GROUND 
  • Neutral switch and keyless control module connectors are disconnected.
  • Inspect for continuity between the following terminal (wiring harness-side) and body ground:
    • Neutral switch terminal A
  • Is there continuity?
 Yes Repair or replace the wiring harness for a possible short to ground, then go to Step 9.
No Go to the next step.
7 INSPECT NEUTRAL SWITCH POWER SUPPLY CIRCUIT FOR SHORT TO POWER SUPPLY 
  • Neutral switch and keyless control module connectors are disconnected.
  • Reconnect the negative battery cable.
  • Switch the ignition to ON.
  • Measure the voltage at the following terminal (wiring harness-side):
    • Neutral switch terminal A
  • Is there any voltage?
 Yes Repair or replace the wiring harness for a possible short to power supply, then go to Step 9.
No Go to the next step.
8 INSPECT NEUTRAL SWITCH POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT 
  • Neutral switch and keyless control module connectors are disconnected.
  • Switch the ignition to off.
  • Disconnect the negative battery cable.
  • Inspect for continuity between the following terminals (wiring harness-side):
    • Neutral switch terminal A-Keyless control module terminal 4X
  • Is there continuity?
 Yes Go to the next step.
No Repair or replace the wiring harness for a possible open circuit, then go to the next step.
9 VERIFY TROUBLESHOOTING COMPLETED 
 Yes Replace the keyless control module, then go to the next step.
(See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION ).
No Go to the next step.
10 VERIFY THAT NO OTHER DTCs ARE PRESENT 
  • Are any DTCs present?
 Yes Go to the applicable DTC inspection.
(See DTC TABLE [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ).
No DTC troubleshooting completed.
