Control Module: Testing and Inspection

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