Probe the pin you want to testBut use the solenoid test chart, if its failing the test then you have an open circuit either in the wire or in the solenoid
Only proceed to tear into the box when you have exhausted your steps
Actually I am talking about this wire
I know this wiring harness. It almost never goes bad unless a mechanic breaks it.
Have you tested the circuit as I posted above? its basic common troubleshooting knowledge, if you cannot DIY it, then pay a good mechanic to diagnose it for you.
I followed this chart
What should be the body ground??? I mean I connect red of DMM to pin of txn wire and black with battery negative and check resistance??? Is this correct???
ground to transmission case or battery negative.
I grounded to transmission case and touched all 10 pins of transaxle wire with red probe of DMM but nothing happened reading stayed on 1-
Tomorrow I will try with battery negative terminal
Thats testing for shorts only
Test the pin of the wiring plug that leads to the solenoid you wish to test, if its not showing correct resistance of the solenoid then test further
Testing for short to ground is only 1% diagnosis
I dont know exactly out of the 10 which pin is of TCC solenoid as there is no Wiring diagram available for my specific model. I found some diagrams but they belong to USA models
Were you able to trace the wire from the ecu to gearbox connector plug?
i have a query regarding this particular transmission, when we completely release the brake while in Drive mode, does the clutch fully engage? whether we push gas pedal or not?
Vb is a internal part. Solenoids are under the chamber of tranny.
I did not trace the wire just checked all pins one by one in the connector
Which clutch you are talking about??
Are you assuming an automatic has a clutch plate like a manual box?
Sp basically you didnt do any diagnosis
the lock up clutch in he torque converter assembly,
that doesnt apply till transmission gets to 4th (overdrive) and engine dynamic torque is reduced.
Sir I am not getting your point kindly explain me considering me as a layman. Basically so far what I have done is I connected OBD2 device and performed Active test on Lockup Solenoid but forcing it to ON while driving at 60km/h . The scanner showed ON but in actual no difference observed in RPM but when I reduced speed like to 40km/h the LOCK UP status changed to OFF automatically on OBD2 scanner so I assummed that ECU is doing its function correctly now you tell is it correct or not???
