Tester LEDs and Controls

TESTER 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).

Note All LEDs light orange during On-Board Diagnostic.

3. Solenoid Activate Buttons: energize respective solenoids and selected circuits.
4. Bench/Drive Switch: selects operating mode.
5. Solenoid/Gear Select Switch: has three functions:
- Bench Mode: acts as shift solenoid selector for click testing.
- Drive Mode: acts as gear selector in place of PCM control.

Note
- Hydraulic safety mechanisms are built into the transmission.
- Ohms Check: allows circuit resistance tests.
