TCM Inspection: Notes
WARNING: This page is about a different car, the 2004 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- The TCM terminal voltages vary with changes in measuring and vehicle conditions. Always carry out a total inspection of the input and output systems, and the TCM to determine the cause of trouble. Otherwise, a mis-diagnosis could occur.
- Measure the voltage at each terminal.
- If any incorrect voltage is detected, inspect the related system (s), wiring harnesses and connector (s) referring to the Action column in the terminal voltage table.
