POSSIBLE CAUSE
•  Multiplex communication system DTC is stored
•  Neutral switch connector or terminals malfunction
•  Open circuit in wiring harness between the following terminals:
―  Neutral switch terminal B—Body ground
•  Neutral switch malfunction
•  Keyless control module connector or terminals malfunction
•  Short to ground in wiring harness between the following terminals:
―  Neutral switch terminal A—Keyless control module terminal 4X
•  Short to power supply in wiring harness between the following terminals:
―  Neutral switch terminal A—Keyless control module terminal 4X
•  Open circuit in wiring harness between the following terminals:
―  Neutral switch terminal A—Keyless control module terminal 4X
•  Keyless control module malfunction

Diagnostic Procedure

Step

Inspection

Action
1
VERIFY RELATED STORED DTC
•  Perform the advanced keyless entry and push button start system DTC inspection using the M-MDS.
•  Is the DTC U0001:88, U0100:00 or U0121:00 also present?
Yes
Go to the applicable DTC inspection.
(See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (L.H.D. (MZR-CD 2.2))].)
(See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (L.H.D. (EXCEPT MZR-CD 2.2, MZR 2.0 DISI i-stop))].)
(See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (R.H.D. (MZR-CD 2.2))].)
(See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (R.H.D. (EXCEPT MZR-CD 2.2, MZR 2.0 DISI i-stop, ZY))].)

(See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (R.H.D. (MZR 2.0 DISI i-stop))].)
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
•  Inspect the neutral switch.
•  Is there any malfunction?
Yes
Replace the neutral switch, then go to Step 9.
(See NEUTRAL SWITCH REMOVAL/INSTALLATION [F35M-R].)
(See NEUTRAL SWITCH REMOVAL/INSTALLATION [A26M-R].)
(See NEUTRAL SWITCH REMOVAL/INSTALLATION [G66M-R (EXCEPT MZR 2.0 DISI i-stop)].)
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
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from the keyless control module using the M-MDS.
•  Switch the ignition to off, then to ON.
•  Perform the advanced keyless entry and push button start system DTC inspection using the M-MDS.
•  Is the DTC P081D:62 present?
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.
