DTC DETECTION LOGIC
DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
P0966 | Pressure control solenoid B control circuit low | The primary pressure solenoid valve current is
200 mA or less continuously for 480 msec or
more under the following diagnosis conditions: - Diagnosis conditions - Solenoid valve output current: 750 mA or more - GND short circuit diagnosis occurs in the solenoid valve drive circuit. - TCM power supply voltage: More than 11 V |
- Harness or connector
(Primary pressure solenoid valve circuit
shorted to ground) - Primary pressure solenoid valve |
DTC CONFIRMATION PROCEDURE
1.PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
Is "P0966" detected?
YES >> Go to TM "Diagnosis Procedure".
NO >> INSPECTION END
1.CHECK CIRCUIT BETWEEN TCM AND CVT UNIT
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace malfunctioning parts.
2.CHECK PRIMARY PRESSURE SOLENOID VALVE
Check primary pressure solenoid valve. Refer to TM "Component Inspection (Primary Pressure Solenoid Valve)".
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI "Intermittent Incident".
NO >> Repair or replace malfunctioning parts.
Component Inspection (Primary Pressure Solenoid Valve)
1.CHECK PRIMARY PRESSURE SOLENOID VALVE
Check resistance between CVT unit connector terminal and ground.
Is the inspection result normal?
YES >> INSPECTION END
NO >> There is a malfunction of primary pressure solenoid valve. Replace transaxle assembly. Refer to TM "Removal and Installation".
