Installing the Transaxle Tester

NOTE: The transaxle tester allows the technician to operate the electrical portion of the TR switch.

Installing the Transaxle Tester (Set Up Procedures)
Installing the transaxle tester at the TR switch connector allows the separation of the vehicle electronics from the TR switch electronics.

NOTE: During tester usage, additional DTCs may be set. Therefore, it is important that all DTCs are erased after repairs have been made. To verify the elimination of all DTCs, rerun the On-Board Diagnostic Test.

CAUTION: Do not attempt to pry off connectors with a screwdriver. This will damage the connector and could result in a transaxle concern.

1. Disconnect the emission harness at transaxle TR switch connector.




CAUTION: Route all cables away from heat sources.

2. Set the Bench/Drive switch to "DRIVE" mode. Install the SST onto the tester. Connect the interface cable (cable I.D. "D") to the transaxle tester and then to the TR switch connector.




3. Turn the test select switch to the "MLP SENSOR TEST" position.




4. Plug the transaxle tester power supply plug into the cigarette lighter receptacle.
At this time, all LED's should illuminate for a short period and then turn off. This is the tester internal circuit check.
