Tester Installation Procedures
DESCRIPTIONInstalling the transmission tester at the transmission connector allows separation of the vehicle electronics from transmission electronics. Disconnecting normal vehicle electronics will set additional DTCs and cause firm shifts. (Disconnecting the transmission connector defaults transmission to maximum line pressure).
NOTE: During tester usage additional DTCs may be set. Therefore, it is important that all DTCs are erased after service has been made. To verify elimination of all DTCs rerun On-Board Diagnostic.
NOTE: The following should be used to assist in diagnosis of electronically controlled transmissions:
- Powertrain Management.
- Transmission Tester Manual (provided with tester).
- wiring and vacuum diagrams.
PROCEDURE
1. If the vehicle has heat shields, remove them. Always replace them after service.
2. Disconnect vehicle harness at transaxle connector.
CAUTION: Do not attempt to pry off connectors with a screwdriver. This will damage the connector and could result in a transaxle concern.
3. Attach the appropriate overlay from the AX4S cable and overlay 007-00087 or equivalent to the Rotunda Transmission Tester 007-00130.
4. Turn the SOLENOID SELECT dial to OHMS CHECK position.
CAUTION: For resistance checks be sure that the SOLENOID SELECT dial is set to the OHMS CHECK position, or damage to the ohmmeter could result.
5. Connect the appropriate interface cable to the tester and then to the transaxle connector.
CAUTION: Route all cables away from heat sources to prevent damage to cables during testing.
6. Install a 0.0-2500 kPa (0.0-300 psi) line pressure gauge into line pressure tap on case.
