DTC P07BE:00	Transmission indeterminate failure (failed to neutral)
DETECTION CONDITION	• Correlation malfunction between neutral switches No.1 and No.2. Diagnostic support note • This is a continuous monitor (other). • The MIL does not illuminate. • FREEZE FRAME DATA (Mode 2)/Snapshot data is not available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• Neutral switch No.2 connector or terminals malfunction • Open circuit in wiring harness between neutral switch No.2 terminal B and body ground • Neutral switch No.2 malfunction • Short to ground in wiring harness between neutral switch No.2 terminal A and PCM terminal 1AJ • PCM connector or terminals malfunction • Short to power supply in wiring harness between neutral switch No.2 terminal A and PCM terminal 1AJ • Open circuit in wiring harness between neutral switch No.2 terminal A and PCM terminal 1AJ • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
1		No	Go to the next step.
2	VERIFY RELATED PENDING CODE AND/OR DTC • Switch the ignition to off, then to ON (engine off). • Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [MZR 2.0 DISI i-stop].) • Is the PENDING CODE/DTC P0850:00 also present?	Yes	Go to the applicable PENDING CODE or DTC inspection. (See DTC P0850:00 [MZR 2.0 DISI i-stop].)
2		No	Go to the next step.
3	INSPECT NEUTRAL SWITCH NO.2 CONNECTOR CONDITION • Switch the ignition to off. • Disconnect the neutral switch No.2 connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal and/or connector, then go to Step 10.
3		No	Go to the next step.
4	INSPECT NEUTRAL SWITCH NO.2 GROUND CIRCUIT FOR OPEN CIRCUIT • Neutral switch No.2 connector is disconnected. • Inspect for continuity between neutral switch No.2 terminal B (wiring harness-side) and body ground. • Is there continuity?	Yes	Go to the next step.
4		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 10.
5	INSPECT NEUTRAL SWITCH NO.2 • Inspect the neutral switch No.2. (See NEUTRAL SWITCH INSPECTION [MZR 2.0 DISI i-stop].) • Is there any malfunction?	Yes	Replace the neutral switch No.2, then go to Step 10. (See NEUTRAL SWITCH NO.2 REMOVAL/INSTALLATION [G66M-R (MZR 2.0 DISI i-stop)].)
5		No	Go to the next step.
6	INSPECT NEUTRAL SWITCH NO.2 SIGNAL CIRCUIT FOR SHORT TO GROUND • Neutral switch No.2 connector is disconnected. • Inspect for continuity between neutral switch No.2 terminal A (wiring harness-side) and body ground. • Is there continuity?	Yes	If the short to ground circuit could be detected: • Repair or replace the wiring harness for a possible short to ground. If the short to ground circuit could not be detected: • Replace the PCM (short to ground in PCM internal circuit). (See PCM REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].) Go to Step 10.
6		No	Go to the next step.
7	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal and/or connector, then go to Step 10.
7		No	Go to the next step.
8	INSPECT NEUTRAL SWITCH NO.2 SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY • Neutral switch No.2 and PCM connectors are disconnected. • Switch the ignition to ON (engine off). • Measure the voltage at the neutral switch No.2 terminal A (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 10.
8		No	Go to the next step.
9	INSPECT NEUTRAL SWITCH NO.2 SIGNAL CIRCUIT FOR OPEN CIRCUIT • Neutral switch No.2 and PCM connectors are disconnected. • Switch the ignition to off. • Inspect for continuity between neutral switch No.2 terminal A (wiring harness-side) and PCM terminal 1AJ (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
10	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR 2.0 DISI i-stop].) • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [MZR 2.0 DISI i-stop].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].) Go to the next step.
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZR 2.0 DISI i-stop].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR 2.0 DISI i-stop].)
11		No	DTC troubleshooting completed.
