MLP Tester Setup

Installing the Transmission Tester (Set Up Procedures)

Installing the transmission tester at the TR sensor connector allows the separation of the vehicle electronics from the TR sensor 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 elimination of all DTCs rerun On-Board Diagnostic Test.






1. Disconnect emission harness at transmission TR sensor connector. For in vehicle testing, use the SST.

Caution: Do not attempt to pry off connectors with a screwdriver. This will damage the connector and could result in a transmission concern. Route all cables away from heat sources.

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






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






4. Plug transmission tester power supply plug into 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.
