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".
Fuel pressure check
Work Procedure
FUEL PRESSURE RELEASE
1.FUEL PRESSURE RELEASE
With CONSULT
Turn ignition switch ON.
Perform "FUEL PRESSURE RELEASE" in "WORK SUPPORT" mode with CONSULT.
Start engine.
After engine stalls, crank it two or three times to release all fuel
pressure.
Turn ignition switc ...
P0734 4GR Incorrect ratio
Description
This malfunction is detected when the A/T does not shift into 4GR position as
instructed by TCM. This is not
only caused by electrical malfunction (circuits open or shorted) but by
mechanical malfunction such as control
valve sticking, improper solenoid valve operation, etc.
