Tester Installation Procedures

Installing the Rotunda Transmission Tester 007-00130 (part of Rotunda Transmission Tester Kit) and TR Testing Cable "E" 007-00111 and Digital TR Sensor Overlay 007-00131 at the transmission connector allows separation of the DTR sensor electronics from the vehicle electronics.

Testing may cause additional fault codes to be set. Therefore, it is important that all DTCs are erased whenever repairs are made. To verify elimination of all codes, rerun OBD test.

1. For proper DTR sensor diagnosis, follow Pinpoint Test D.
2. Disconnect vehicle harness at transmission DTR sensor.
3. Set the two-way switch in the down position. (This switch will stay in the same position for all DTR sensor testing.)





4. Attach the Digital TR Sensor Overlay 007-00131 to the transmission tester.
- Affixing the overlay will immobilize the two-way switch (set in Step 2) so it cannot be accidentally moved to an incorrect setting during testing.





5. Select and connect interface cable "E" 007-00111 to the tester and then black connector (digital) to DTR sensor.





6. Set analog/digital switch on TR-E cable to digital.

CAUTION: Route all cables away from heat sources to prevent damage to cables during testing.

Use the transmission tester extender cable when running tests with the transmission on the vehicle.





7. Turn large dial to DIGITAL TR SENSOR TEST.
8. Plug transmission tester power cable into cigar lighter socket.

All LEDs should light for a short period and then turn off. This is the Tester's internal circuit check.

CAUTION: For resistance checks, be sure that the tester selector switch is set to the TR SENSOR TEST position or damage to the ohmmeter may result.
