This section shows how to troubleshoot the transmission solenoids/internal harness connections via the TCU main connector C12. Set your multi-meter to read resistance and probe between the indicated terminals. Caution: Be careful not to damage the terminals in the connector with the multi-meter probes.
A short, open or resistance reading outside of the specification indicates a problem that needs to be investigated further. Note: The letters and numbers used to identify the terminals are molded to the connector body.
