Tester Description
DESCRIPTION
Use Rotunda Transmission Tester 007-00085 and Update Kit 007-00125 or equivalent to diagnose electronically controlled transaxles. The following instructions described the set-up and use of this tester in the pinpoint tests.
OVERLAYS AND ADAPTERS
The following transmission tester overlays and adapters must be used with the Rotunda Transmission Tester 007-00085 or equivalent to properly diagnose the transaxle.
- Rotunda Transmission Tester Update 007-00125 or equivalent
- Rotunda TR/MLP Sensor Tester Overlay and Cable 007-00129 or equivalent
TESTER JACKS
1. VPWR Pin Jacks (red): VPWR test points for solenoid circuits.
2. Solenoid (TCC, EPC) Signal Line Pin Jacks (black): Signal line test points for solenoid circuits.
3. BAT+ (red) and BAT-(black) Pin Jacks: Battery reference points when measuring circuits for shorts.
4. TFT Pin Jacks: Test points for transmission fluid temperature (TFT).
5. TSS Pin Jacks: Test points for turbine shaft speed (TSS) sensor.
LEDs AND CONTROLS
1. Overlay and Cable Correctly Installed LEDs:
Only LEDs with the (O) symbol will not light when the overlay and cable match correctly.
2. Status LEDs:
(1) LED OFF when not activated by tester (solenoid not activated, open circuit or signal line short to ground).
(2) LED green when activated by tester and current draw is correct.
(3) LED red when activated by tester and current draw is excessive (short at VPWR).
(4) All LEDs light orange during self-test.
3. Solenoid Activate buttons energize respective solenoids during click testing and activate selected circuits during DRIVE mode testing.
4. Tester Mode switch selects operating mode, either BENCH or DRIVE.
5. The Solenoid Select/Gear Select switch has three functions:
(1) BENCH mode: acts as shift solenoid selector for click testing.
(2) DRIVE mode: acts as forward gear selector in place of vehicle's PCM-controlled shifting. Hydraulic safety mechanisms and overrides are built into the transaxle.
(3) OHMS check: allows you to measure ohms and to check for presence of a diode on specific solenoids.
INSTRUCTIONS
The Rotunda Transmission Tester 007-0085D or equivalent allows a technician to operate the electrical portion of the transmission independent of the vehicle electronics. This allows the technician to determine transmission concerns. The transmission tester usage is divided in five steps:
1. Preliminary testing and diagnosis
2. Installing the transmission tester
3. Static testing-engine OFF
4. Dynamic testing-engine running
5. Removing transmission tester and clearing diagnostic trouble codes
