DTC P0010 [MZI-3.7] 

DTC P0010 (MZI-3.7) DETECTION CONDITIONS AND POSSIBLE CAUSES 

1



Clear the DTC from the PCM memory using the 
M-MDS.  



Perform the PCM parameter reset using the M-
MDS. 

(See IMMOBILIZER SYSTEM 
COMPONENT REPLACEMENT/KEY 
ADDITION AND CLEARING [ADVANCED 
KEYLESS SYSTEM] .) (See IMMOBILIZER 
SYSTEM COMPONENT 
REPLACEMENT/KEY ADDITION AND 
CLEARING [KEYLESS ENTRY 
SYSTEM] .) 



Is same DTC present?  

Yes

Replace the PCM, then go to the next 
step. (See PCM 
REMOVAL/INSTALLATION 
[MZI-3.7] .)

No

Go to the next step.

2

VERIFY AFTER REPAIR PROCEDURE  



Perform the "AFTER REPAIR PROCEDURE". 

(See AFTER REPAIR PROCEDURE [MZI-
3.7].) 



Are any DTC present?  

Yes

Go to the applicable DTC inspection. 
(See DTC TABLE [MZI-3.7].)

No

Troubleshooting completed.

DTC P0010

CMP actuator circuit open (RH)

DETECTION 

CONDITION 



The PCM monitors the OCV (RH) circuit to the PCM for high and low voltage. The
test fails if the voltage exceeds or falls below a calibrated limit for a calibrated 
amount of time.  

POSSIBLE CAUSE 



OCV (RH) malfunction  



Connector or terminal malfunction  



Open circuit between OCV (RH) terminal A and main relay No.1 terminal D  



Open circuit between OCV (RH) terminal B and PCM terminal 2BP  



Short to ground circuit between OCV (RH) terminal B and PCM terminal 2BP  



Short to power supply between OCV (RH) terminal B and PCM terminal 2BP
