REMOTE ENGINE STARTER CHARACTERISTICS

(a) The operation distance varies according to how customers hold the transmitter or where it is used.

(b) Strong external radio waves or other frequency noise may interfere with the Remote Engine Starter’s operation distance.

REMOTE ENGINE STARTER BASIC FUNCTIONS

(a) Stand on the driver’s side, three feet away from the vehicle.

(b) Turn the transmitter toward the vehicle and press and release the LOCK button twice within two seconds. Immediately press and hold the LOCK button for three seconds. The hazard lights flash after three seconds.

(c) The engine then starts, and the hazard lights flash for 20 seconds.

(d) Press the UNLOCK button. The engine stops and hazard lights flash twice.ORPress and hold the LOCK button for two or more seconds. The engine stops and the hazard lightsflash once.

DIAGNOSTIC OPERATION

ENGINE STARTER DIAGNOSIS

NOTE: Turn the engine off before performing any diagnostic function.

The Diagnostic Mode can help determine why the engine stops/fails.To set the Diagnostic Mode, you must locate and connect the Diagnostic Connectors (RDIG). To do so, follow the steps below:

(1) Remove the passenger side step cover.

(2) Remove the passenger side cowl cover.

(3) Find and connect the Diagnostic Connectors (RDIG) with label, located in the passengercowl area.

RES DiagnosticConnectors

Theseconnectorsmust be connected.

Diagnostic Operation

DIAGNOSTIC FACTOR IDENTIFICATION

The Diagnostic Mode indicates the causes of engine stop or failure to start as listed below.

Engine Stop Factor

*1: The immobilizer registration should be confirmed if the connection and terminal signal don’t have any problem. (Only installation timing)

*2: When two or more of these conditions are responsible for the engine stop or non-start, they will be indicated by order of priority.

Press the Brake pedal: < OFF ON (Press) >

Connect the diagnostic connector: < Open GND (Connect) >

Wait for more than 3 seconds


DIAGNOSTIC MODE EXIT CONDITIONS

You may exit the Diagnostic Mode by doing either of the following:

1: Disconnect the diagnostic connectors.OR2: Wait 10 minutes from the time the diagnostic connectors were connected.

After completing the repair, the diagnostic connectors should be disconnected and re-secured prior to reassembly of the trim covers.

NOTE: The Remote Engine Starter will store the code for the last engine stop factor in its memory, even after exiting Diagnostic Mode. The code cannot be cleared from the Remote Engine Starter ECU’s memory.

DIAGNOSTIC CODE BY SCAN TOOL

When RES has the following defects, diagnostic code is indicated by the scan tool.

1: Internal Relay of the RES ECU Abnormality Detected CODE [B2334] 2: Internal Switch of the RES ECU for Vehicle Starter Abnormality Detected CODE [B2333]

If you find the above code by the scan tool, PLEASE CALL Fujitsu Ten Technical Support at (800) 237-5413.


INSPECTION 1/9

(a) Ignition must be “OFF” when starting this procedure.

(a) Press the LOCK button. (b) Confirm the doors are locked.

<Smart Entry Vehicle> (a) Start the engine with the POWER button. (b) Confirm the engine is activated.

4 CHECK REMOTE ENGINE STARTER DIAGNOSIS

(a) Please check the diagnostic code by scan tool. (See “Diagnostic Code by Scan Tool” on page 12). If [B2334] or [B2333] is indicated, please call Fujitsu Ten Technical Support at (800) 237-5413.

(b) Connect the diagnostic connectors to enter the Diagnostic Mode. (See “Diagnostic Operation” on page 10 for the location of the connectors). If the connectors are already plugged in, please disconnect and plug them in again. (c) Check the factor to stop the engine by applying the brake in Diagnostic Mode. Hazard lights will flash in accordance with the factor of engine stop. (See “Diagnostic Factor Identification” on page 11.)

Measure the voltage and resistance of the affected terminals (listed on page 11) on the wire harness for Remote Engine Starter ECU and Accessory Gateway ECU. Then, compare measured value to specifications. (See RES ECU and Accessory Gateway ECU pin layout and terminal information from pages 4 to 6 for specifications.)

Measure the voltage and resistance of the other or all terminals on the wire harness for Remote Engine Starter ECU and Accessory gateway ECU. Then, compare measured value to specifications. (See RES ECU and Accessory Gateway ECU pin layout and terminal information from pages 4 to 6 for specifications.)

Check for continuity of the wire harness. (See Installation Instruction and Electrical Wiring Diagram.)

ENGINE STOPS UNEXPECTEDLY

2 CHECK REMOTE ENGINE STARTER DIAGNOSIS

HINT: EXPLAIN HOW ENGINE STARTER WORKS TO CUSTOMER:Any vehicles started with the Remote Engine Starter can idle for a total 20 minutes. Automatic engine shutdown occurs after 10 minutes, but the vehicle may be remotely started as many times as the user wishes and run for an additional 10 minutes. After 20 minutes of total operation, however, the vehicle must be started manually to reset the Remote Engine Starter.
