TCM Inspection: Notes
WARNING: This page is about a different variant/trim than selected.
CAUTION:
- Do not allow foreign material or water to penetrate the connector. Otherwise, it could cause poor contact and corrosion.
NOTE:
- The TCM terminal voltage can vary depending on conditions when measuring, and deterioration over time of the vehicle which may cause false diagnosis. Therefore, a comprehensive diagnosis must be performed to determine whether the malfunction is occurring in the input system, output system, or the TCM.
- Connect the negative (-) lead of the tester to the GND.
- Measure each terminal voltage of the TCM using a tester.
- If output voltage is abnormal even though input voltage is normal, inspect the related system. If the related system is normal, replace the TCM. (See TCM REMOVAL/INSTALLATION .)
