TCM Inspection: Notes

NOTE:
  • The TCM terminal voltage can vary with conditions when measuring and changes due to age deterioration on the vehicle, causing false diagnosis. Therefore a comprehensive inspection of the input and output systems, and the TCM is necessary to determine where the malfunction occurs.
  1. Measure the terminal voltage of the TCM using a tester.
