DTC DETECTION LOGIC
DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
P0983 | Shift Solenoid D Control Circuit High | The following diagnosis conditions
are met, and the current
monitor reading of the TCM line
pressure solenoid valve is 200
mA or less continuously for 0.5
seconds or more. - Diagnosis condition - Solenoid valve output current: 750 mA or more - TCM power supply voltage: 10 V < TCM power supply voltage < 16 V |
- Harness or connector
(High clutch/low & reverse
brake solenoid valve circuit is
open or shorted to power
supply.) - High clutch/low & reverse brake solenoid valve |
DTC REPRODUCTION PROCEDURE
CAUTION: Be careful of the driving speed.
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
Selector lever : D position
Gear : 3GR, 4GR
Vehicle speed : 45 km/h (28 MPH) or more
Is "P0983" detected?
YES >> Go to TM, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK CIRCUIT BETWEEN TCM AND A/T UNIT
Is the check result normal?
YES >> GO TO 2.
NO >> Repair or replace the malfunctioning parts.
2.CHECK HIGH CLUTCH/LOW & REVERSE BRAKE SOLENOID VALVE
Check the high clutch/low & reverse brake solenoid valve. Refer to TM, "Component Inspection (High Clutch Solenoid Valve)".
Is the check result normal?
YES >> Check intermittent incident. Refer to GI "Intermittent Incident".
NO >> Repair or replace the malfunctioning parts.
Component Inspection (High Clutch Solenoid Valve)
1.CHECK HIGH CLUTCH/LOW & REVERSE BRAKE SOLENOID VALVE
Check the resistance between the A/T unit connector and ground.
Is the check result normal?
YES >> INSPECTION END
NO >> There is a malfunction of the high clutch/low & reverse brake solenoid valve. Replace the transaxle assembly. Refer to TM "Removal and Installation".

P0731 1GR Incorrect ratio
Description
This malfunction is detected when the A/T does not shift into 1GR 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.

Work Procedure
INSPECTION
Check the engine oil level. Replenish if necessary. Refer to LU
"Inspection".
Check for CVT fluid leaks. Refer to TM "Inspection".
Drive for about 10 minutes to warm up the vehicle so that the CVT fluid
temperature is 50 to 80C (122 to
