[EXC.F/EURO-OBD]
TROUBLE DIAGNOSES FOR SYMPTOMS
5. DETECT MALFUNCTIONING ITEM
1. Remove control valve assembly. Refer to AT- 4 0 6 , "
Control Valve Assembly and Accumulators" .
2. Check the following items:
–Torque converter clutch control valve
–Pilot valve
–Pilot filter
3. Disassemble A/T.
4. Check torque converter and oil pump assembly.
OK or NG
OK >> GO TO 4
NG >> Repair or replace damaged parts.
14. Lock-up Is Not ReleasedECS007RD
SYMPTOM:
Lock-up is not released when accelerator pedal is released.
1. CHECK THROTTLE POSITION SENSOR* CIRCUIT
*: This sensor means accelerator pedal position (APP) sensor.
With CONSULT-II
Does “TCM INPUT SIGNALS” in “DATA MONITOR” show damage throttle position sensor circuit?
Without CONSULT-II
Does self-diagnosis show damage to throttle position sensor circuit?
Ye s o r N o
Yes >> Check throttle position sensor circuit. Refer to AT- 3 3 3 ,
"21. TCM Self-diagnosis Does Not Activate (PNP &
Overdrive Control Switches, and Throttle Position Sen-
sor Circuit Checks)" .
No >> GO TO 2
2. CHECK SYMPTOM
Check again.
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
15. Engine Speed Does Not Return To Idle (Light Braking D4→ D3 )ECS007RE
SYMPTOM:
●Engine speed does not smoothly return to idle when A/T shifts from D4 to D3 .
●Vehicle does not decelerate by engine brake when turning overdrive control switch OFF.
●Vehicle does not decelerate by engine brake when shifting A/T from “D” to “2” position.
