DTC DETECTION LOGIC
DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
P099B | Shift solenoid G control circuit low | The TCM high clutch & reverse brake solenoid
valve current monitor reading is 200 mA or
less continuously for 200 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
(High& clutch reverse brake solenoid
valve circuit shorted to ground) - High clutch & reverse 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 "P099B" 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 HIGH CLUTCH & REVERSE BRAKE SOLENOID VALVE
Check high clutch & reverse brake solenoid valve. Refer to TM "Component Inspection (High Clutch & Reverse 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 (High Clutch & Reverse Brake Solenoid Valve)
1.CHECK HIGH CLUTCH & REVERSE 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 high & reverse brake solenoid valve. Replace transaxle assembly.
Refer to TM "Removal and Installation".
