Tester Description

Use Rotunda Transmission Tester 007-00130 007-00130 with AX4S cable and overlay 418-F029 (007-00087) (007-00087) or equivalent to diagnose electronically controlled transaxles. The following instructions describe the set-up and use of this tester in the pinpoint tests for the AX4S.

OVERLAYS AND ADAPTERS





The following transmission tester overlays and adapters must be used with the Rotunda Transmission Tester 007-00130 007-00130 or equivalent to properly diagnose the AX4S transaxle.
- Rotunda TR/MLP Sensor Tester Overlay part of kit 418-F128 (007-0086B) or equivalent
- Rotunda Digital TR Sensor Tester Overlay 007-00131 or equivalent
- Rotunda AX4S Transmission Tester cable and overlay 418-F029 (007-00087) (007-00087) or equivalent
- Rotunda Transmission Range (TR) Sensor Cable E (MLPS Cable) 418-F107 (007-00111).

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 sensor.
5. TSS Pin Jacks: Test points for turbine shaft speed sensor.

LEDS AND CONTROLS
1. Overlay and Cable Correctly Installed LEDs: Only LEDs with symbol and cable correctly match.
2. Status LEDs: LED OFF when not activated by tester (solenoid not activated, open circuit or signal line short to ground). LED green when activated by tester and current draw is correct. LED red when activated by tester and current draw is excessive (short to battery positive voltage (B+)). All LEDs light orange during On-Board Diagnostic.
3. Solenoid Activate Buttons: Energize respective solenoids during click testing and activate selected circuits during DRIVE mode testing.
4. Bench/Drive Switch: Selects operating mode, either BENCH or DRIVE.
5. Solenoid Select/Gear Select Switch: Has three functions:
- In BENCH MODE: acts as shift solenoid selector for click testing.
- In 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.
- In OHMS CHECK: allows you to measure ohms.

INSTRUCTIONS
The Rotunda Transmission Tester 007-00130 007-00130 with AX4S cable and overlay 418-F029 (007-00087) (007-00087) or equivalent allows a technician to operate the electrical portion of the transaxle independent of the vehicle electronics to determine specific transaxle concerns. Transmission tester usage is divided into five steps:
1. Preliminary testing and diagnosis
2. Installing the transmission tester
3. Static testing-engine OFF
4. Dynamic testing-engine running
5. Removing the transmission tester and clearing Diagnostic Trouble Codes (DTCs).
