System Description

Remote Control Engine Starter Operation

1. Press the start button of the transmitter to send the start signal.

2. When the control unit receives the start signal, it checks the start conditions listed below.

3. When the start conditions listed above have been met, the control unit switches on the IG1 relay and checks the start conditions listed below.

4. When the start conditions listed above have been met, the control unit switches on the starter signal to start the engine.

5. When the charge indicator goes off, the control unit interprets this to mean that the “engine has started”, and it switches off the starter signal.

6. When the engine starts successfully, the control unit turns on the IG2 relay and transfers to the warm-up operation.

7. When one of the conditions listed below is input during the warm-up operation, the control unit switches off the IG1 relay and IG2 relay to stop the engine.

• All doors are closed. (Door switches: OFF)

• Tailgate is closed. (Tailgate latch switch: OFF)

Self-diagnostic Function

Checking the Engine (Doesn’t) Run History

If the engine has failed to start, the engine (doesn’t) run history of the engine can be displayed by the transmitter.By taking the following steps, the last 8 events in the engine (doesn’t) run history are displayed in sequence starting with the latest event.* For details of the displays, refer to the symptom-to-cause chart (see page 8)

1. While keeping the transmitter’s ENGINE button pressed, hold down the LOCK button, and after five seconds check that ERROR HISTORY is displayed.

2. CHECKING is displayed on the transmitter, and the engine (doesn’t) run history events are displayed in sequence starting from event 1.

* If there are fewer than 8 engine (doesn’t) run history events, the operation is completed as soon as the saved history is displayed. If there are no engine (doesn’t) run history events, NO ERROR is displayed on the transmitter.
