DETECTION CONDITION
•  CAN and P position switch signals do not correspond, while ignition switch is ON.
POSSIBLE CAUSE
•  Selector lever component connector or terminals malfunction
•  Keyless control module connector or terminals malfunction
•  Short to ground in wiring harness between selector lever component terminal G and keyless control module terminal 3M
•  Short to power supply in wiring harness between selector lever component terminal G and keyless control module terminal 3M
•  Selector lever component malfunction
•  Open circuit in wiring harness between selector lever component terminal G and keyless control module terminal 3M
•  Keyless control module malfunction

Diagnostic Procedure

Step

Inspection

Action
1
INSPECT SELECTOR LEVER COMPONENT CONNECTOR CONDITION
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Disconnect the selector lever component 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 7.
No
Go to the next step.
2
INSPECT KEYLESS CONTROL MODULE CONNECTOR CONDITION
•  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 7.
No
Go to the next step.
3
INSPECT P POSITION SWITCH CIRCUIT FOR SHORT TO GROUND
•  Selector lever component and keyless control module connectors are disconnected.
•  Inspect for continuity between selector lever component terminal G (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to ground, then go to Step 7.
No
Go to the next step.
4
INSPECT P POSITION SWITCH CIRCUIT FOR SHORT TO POWER SUPPLY
•  Selector lever component and keyless control module connectors are disconnected.
•  Reconnect the negative battery cable.
•  Switch the ignition to ON.
•  Measure the voltage at the selector lever component terminal G (wiring harness-side).
•  Is there any voltage?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to Step 7.
No
Go to the next step.
5
INSPECT SELECTOR LEVER COMPONENT
•  Inspect the selector lever component.
•  Is there any malfunction?
Yes
Replace the selector lever component, then go to Step 7.
(See AUTOMATIC TRANSAXLE SHIFT MECHANISM REMOVAL/INSTALLATION.)
No
Go to the next step.
6
INSPECT P POSITION SWITCH CIRCUIT FOR OPEN CIRCUIT
•  Selector lever component and keyless control module connectors are disconnected.
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Inspect for continuity between selector lever component terminal G (wiring harness-side) and keyless control module terminal 3M (wiring harness-side).
•  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.
7
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.
•  Perform the advanced keyless entry and push button start system DTC inspection using the M-MDS.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
If the malfunction recurs, replace the keyless control module, then go to the next step.
(See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
No
Go to the next step.
8
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.
