DTC P0606:00 [MZR 2.0 DISI i-stop]

id0102d4705900

DTC P0606:00

PCM processor error

DETECTION CONDITION

•  The PCM internal CPU malfunction.

•  Abnormal voltage applied to the PCM ignition switch terminal.

Diagnostic support note

•  This is a continuous monitor (CCM).

•  The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Voltage of 1.0 V or more is applied to PCM ignition switch terminal (PCM terminal 1AY) even though ignition switch is off.

•  PCM internal CPU malfunction

DTC P0606:00	PCM processor error
DETECTION CONDITION	• The PCM internal CPU malfunction. • Abnormal voltage applied to the PCM ignition switch terminal. Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA (Mode 2)/Snapshot data is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• Voltage of 1.0 V or more is applied to PCM ignition switch terminal (PCM terminal 1AY) even though ignition switch is off. • PCM internal CPU malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2	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.
2		No	Go to the next step.
3	VERIFY VOLTAGE AROUND PCM IGNITION SWITCH TERMINAL • When the ignition switch is off, verify that the voltage around the PCM ignition switch terminal (PCM terminal 1AY) is less than 1.0 V. Note • If the measured value fluctuates above and below 1.0 V, place the measurement position close to the PCM and measure several times. • Is the voltage less than 1.0 V?	Yes	Go to the next step.
3		No	Inspect the PCM power supply circuit for open or short circuit. Repair or replace the suspected wiring harness, then go to the next step.
4	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].) • Start the engine. • 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.
4		No	Go to the next step.
5	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].)
5		No	DTC troubleshooting completed.
