DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
P0973 | Shift Solenoid "A" Control Circuit Low | The following diagnosis conditions
are met, and the TCM select
switch ON-OFF solenoid
valve monitor value is ON continuously
for 0.5 seconds or
more. - Diagnosis condition - select switch ON-OFF solenoid valve: OFF - TCM power supply voltage: 10 V < TCM power supply voltage < 16 V |
- Harness or connector
(Short circuit to ground in the
select switch ON-OFF solenoid
valve circuit) - Select switch ON-OFF solenoid valve |
DTC CONFIRMATION 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
3. Check the first trip DTC.
Is "P0973" 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 SELECT SWITCH ON-OFF SOLENOID VALVE
Check the select switch ON-OFF solenoid valve. Refer to TM, "Component Inspection (Select Switch ONOFF 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 (Select Switch ON-OFF Solenoid Valve)
1.CHECK SELECT SWITCH ON-OFF 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 select switch ON-OFF solenoid valve. Replace the transaxle assembly.
Refer to TM, "Removal and Installation".
