Control Module: Testing and Inspection

Inspection
1. Remove the transmission control module.
2. Disconnect the control module connectors.
3. Connect the SSTs (Engine Signal Monitor and Adapter Harness) to the control unit as shown.




4. Place the SST (Sheet) on the Engine Signal Monitor.
5. Turn the ignition switch ON.
6. Measure the terminal voltage at each terminal.
7. If any control unit terminal voltage is incorrect, check the related input of output devices and wiring. If no problem is found, replace the transmission control module.




Caution: Applying voltage to terminals A and B of the SST will damage the SST.
