DTC DETECTION LOGIC
DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
P0998 | Shift solenoid F control circuit low | The TCM low brake solenoid valve current
monitor reading 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
(Low brake solenoid valve circuit shorted
to ground) - Low brake 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 "P0998" 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 LOW BRAKE SOLENOID VALVE
Check low brake solenoid valve. Refer to TM "Component Inspection (Low Brake Solenoid Valve)".
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI "Intermittent Incident".
NO >> Repair or replace malfunctioning parts.
Component Inspection (Low Brake Solenoid Valve)
1.CHECK LOW BRAKE 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 low brake solenoid valve. Replace transaxle assembly. Refer to TM "Removal and Installation".
