TRANSMISSION CONTROL MODULEPreparation
SST:
Inspection
1. Lift out the transmission control module by referring to the transmission control module replacement procedure.
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 or output devices and wiring. If no problem is found, replace the transmission control module.
CAUTION: Applying voltage to terminals A and B of this SST will damage the SST.
NOTE: If the tires are rotated by using a chassis roller with the ignition switch at ON, the ABS control module may memorize the action as a malfunction and the ABS warning light may illuminate. (Refer to the Troubleshooting Notes for the antilock brake system.) If the ignition switch is turned to LOCK and then to ON again, the ABS warning light will not illuminate, because the action will be considered a past malfunction.
