DTC detection condition

Possible causes

P099B SHIFT SOLENOID G (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

  1. Start the engine and wait for 5 seconds or more.
  2. Check the first trip DTC.

Is “P099B” detected? YES >> Go to TM-214, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK CIRCUIT BETWEEN TCM AND CVT UNIT

  1. Turn ignition switch OFF.
  2. Disconnect TCM connector and CVT unit connector.
  3. Check continuity between TCM harness connector terminal and ground.

Is the inspection result normal?


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-214, "Component Inspection".

Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".

NO >> Repair or replace malfunctioning parts.

Component Inspection

1.CHECK HIGH CLUTCH & REVERSE BRAKE SOLENOID VALVE

Check resistance between CVT unit connector terminal and ground.

Is the inspection result normal?


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-283, "Removal and Installation".
