DTC P081D:62 [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM]

id09021c406200

DESCRIPTION

Error signal of neutral switch

DETECTION CONDITION

•  Neutral switch is detected as continuously ON in spite of vehicle speed increasing from 0 km/h {0 mph} to 10 km/h {6.2 mph}.

•  CAN and neutral switch signals do not correspond, while the ignition switch is ON.

POSSIBLE CAUSE

•  Neutral switch connector or terminals malfunction

•  Open circuit in wiring harness between neutral switch terminal A and body ground

•  Neutral switch malfunction

•  Keyless control module connector or terminals malfunction

•  Short to ground in wiring harness between neutral switch terminal B and keyless control module terminal 3T

•  Short to power supply in wiring harness between neutral switch terminal B and keyless control module terminal 3T

•  Open circuit in wiring harness between neutral switch terminal B and keyless control module terminal 3T

•  Keyless control module malfunction

DESCRIPTION	Error signal of neutral switch
DETECTION CONDITION	• Neutral switch is detected as continuously ON in spite of vehicle speed increasing from 0 km/h {0 mph} to 10 km/h {6.2 mph}. • CAN and neutral switch signals do not correspond, while the ignition switch is ON.
POSSIBLE CAUSE	• Neutral switch connector or terminals malfunction • Open circuit in wiring harness between neutral switch terminal A and body ground • Neutral switch malfunction • Keyless control module connector or terminals malfunction • Short to ground in wiring harness between neutral switch terminal B and keyless control module terminal 3T • Short to power supply in wiring harness between neutral switch terminal B and keyless control module terminal 3T • Open circuit in wiring harness between neutral switch terminal B and keyless control module terminal 3T • Keyless control module malfunction

Diagnostic Procedure

Step	Inspection		Action
1	INSPECT NEUTRAL SWITCH CONNECTOR CONDITION • 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 8.
1		No	Go to the next step.
2	INSPECT NEUTRAL SWITCH GROUND CIRCUIT FOR OPEN CIRCUIT • Neutral switch connector is disconnected. • Inspect for continuity between neutral switch terminal A (wiring harness-side) and body ground. • Is there continuity?	Yes	Go to the next step.
2		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 8.
3	INSPECT NEUTRAL SWITCH • Inspect the neutral switch. (See NEUTRAL SWITCH INSPECTION [MZR 1.8, MZR 2.0, MZR 2.5].) (See NEUTRAL SWITCH INSPECTION [MZR 2.0 DISI].) (See NEUTRAL SWITCH INSPECTION [MZR-CD 2.2].) • Is there any malfunction?	Yes	Replace the neutral switch, then go to Step 8. (See NEUTRAL SWITCH REMOVAL/INSTALLATION [G35M-R].) (See NEUTRAL SWITCH REMOVAL/INSTALLATION [G66M-R].) (See NEUTRAL SWITCH REMOVAL/INSTALLATION [A26M-R].)
3		No	Go to the next step.
4	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 8.
4		No	Go to the next step.
5	INSPECT NEUTRAL SWITCH POWER SUPPLY CIRCUIT FOR SHORT TO GROUND • Neutral switch and keyless control module connectors are disconnected. • Inspect for continuity between neutral switch terminal B (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 8.
5		No	Go to the next step.
6	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 neutral switch terminal B (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 8.
6		No	Go to the next step.
7	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 neutral switch terminal B (wiring harness-side) and keyless control module terminal 3T (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
8	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. (See CLEARING DTC [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) • Perform the advanced keyless entry and push button start system DTC inspection using the M-MDS. (See DTC INSPECTION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) • 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].)
8		No	Go to the next step.
9	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].)
9		No	DTC troubleshooting completed.
