PRECAUTION
1.EMERGENCY ENGINE START CONTROL
(a)If there is a malfunction in the stop light switch or STOP fuse, their signals may not be correctly transmitted to the main body ECU. This may result in the engine not starting even if the engine switch is pressed while the brake pedal is depressed and the shift lever is in the P position.
To activate the starter:
(1)Turn the engine switch from off to on (ACC).
(2)Press and hold the engine switch for 15 seconds.
2.PRECAUTIONS FOR PUSH-BUTTON START FUNCTION:
(a)Before starting the engine, firmly depress the brake pedal until the indicator in the engine switch turns green.
(b)The power source mode (off, on (ACC), on (IG)) is always retained in memory by the vehicle. If the battery is disconnected, the power source mode that was present before disconnection will be restored after the battery is reconnected. Be sure to turn the engine switch off before disconnecting the cable from the negative battery terminal. Be careful if the power source mode of a vehicle with a discharged battery is not known.
(c)After the battery is reconnected, be sure to wait 10 seconds or more before attempting to start the engine. The engine may not start immediately after the battery is reconnected.
(d)If the electrical key is held near the engine switch to start the engine when the electrical key battery is depleted, the following warnings will sound:
(1)Driver's door open → closed
•An exit warning will sound if the shift lever is in a position other than P and the power source is in a mode other than off.
•An exit warning will sound if the shift lever is in the P position and the power source is in a mode other than off.
(2)Doors other than the driver door open → closed
•A warning will sound to indicate that the
electrical key has been taken out of the
vehicle. ST These warnings will sound because it is not possible for the
vehicle to determine if the key is present in the vehicle (due to the depleted key battery). These warnings do not indicate system malfunctions.

|
|
|
|
Control |
|
Outline |
|
|
|
|
|
|
|
|
|
• When driver operates engine switch with electrical key in driver's |
|
|
|
|
possession, certification ECU starts indoor electrical key oscillator, |
|
|
|
|
which transmits request signal to electrical key. Upon receiving |
|
|
|
ST |
|||
Engine switch control |
|
this signal, the electrical key transmits ID code signal to main body |
|
|
|
|
ECU. |
|
|
|
|
• ID code box verifies check results received from certification ECU |
|
|
|
|
via LIN and sends them to main body ECU. Based on these |
|
|
|
|
results, main body ECU authorizes operation of engine switch. |
|
|
|
|
|
|
|
Diagnosis |
|
When main body ECU detects malfunction, main body ECU |
|
|
|
diagnoses and memorizes failed section. |

4.CONSTRUCTION AND OPERATION
|
|
Indicator Light |
|
(a) |
Engine Switch |
|
||
|
|
|
|
|
|
The engine switch consists of a momentary type |
||
|
|
|
|
|
|
switch, 3 color (amber, green, greenish white) |
||
|
|
|
|
|
|
LEDs, and a transponder key amplifier. |
||
|
|
|
|
|
|
|||
|
START |
|
|
• The greenish white LED is for illumination. |
||||
|
STOP |
|
|
• The amber and green LEDs are for the indicator |
||||
|
|
|
|
|
|
lights. The driver can check the present power |
||
|
|
|
|
|
|
source mode and whether the engine can start in |
||
|
|
|
A109251E01 |
accordance with the illumination state of the |
||||
|
|
|
|
|
|
indicator light. |
||
|
|
|
|
|
|
|||
|
|
|
|
|
|
• When the main body ECU detects an |
||
|
|
|
|
|
|
abnormality in the push-button start function, it |
||
|
|
|
|
|
|
makes the amber indicator light flash. If the |
||
|
|
|
|
|
|
engine stopped in this state, it may not be |
||
|
|
|
|
|
|
possible to restart it. |

Main body ECU |
|
|
|
|
|
|
|
|
The main body ECU consists of the IG1 and IG2 |
||
|
|
|
|
|
|
relay actuation circuits and CPU. |
||
|
|
|
|
|
|
HINT: |
|
|
Before removing the battery, make sure to turn the engine switch off. The main body ECU constantly stores the present power source mode in its memory. Therefore, if the main body ECU is interrupted by disconnecting the battery, the main body ECU restores the power source mode after the battery is reconnected. For this reason, if the battery is disconnected when the engine switch is not off, the power will be restored to the vehicle at the same time the power is restored to the main body ECU (by reconnecting the battery).
5.PUSH-BUTTON START FUNCTION OPERATION

When the battery of the key is low, the push-button start function can be operated by holding the key against the engine switch.
• After approximately 1 hour has passed with the engine switch on (ACC) and the shift position in P, the main body ECU will automatically cut the power supply (the power source mode changes to off).

|
HINT: |
|
|
While the vehicle is being driven normally, |
|
|
operation of the engine switch is disabled. |
|
|
However, if the engine must be stopped in an |
|
|
emergency while the vehicle is being driven, |
|
|
pressing the engine switch for 3 seconds or more |
|
|
stops the engine. Power source mode changes |
|
|
from start to on (ACC). |
|
6. WHEN KEY BATTERY IS LOW |
|
Required Distance: |
(a) |
To operate the push-button start function when the |
10 mm (0.39 in.) |
|
key battery is low, hold the key close to the engine |
|
|
switch with the brake pedal depressed. |
|
(b) |
The main body ECU transmits a key verification |
|
|
request signal from the stop light switch to the |
|
|
certification ECU. |
Engine Switch |
(c) |
The certification ECU does not receive an ID code |
|
response from the entry door control receiver, so it |
|
|
|
actuates the transponder key amplifier built into the |
|
|
engine switch. |
|
(d) |
The transponder key amplifier outputs an engine |
|
|
immobiliser radio wave to the key. |
|
(e) |
The key receives the radio wave, and returns a |
|
|
radio wave response to the transponder key |
|
|
amplifier. |
Key |
(f) |
The transponder key amplifier combines the key ID |
|
|
codes with the radio wave response, and transmits |
|
|
it to the certification ECU. |
|
(g) |
The certification ECU judges and verifies the ID |
|
B137947E01 |
code, and transmits a key verification OK signal to |
|
|
the main body ECU. The buzzer in the combination |
|
|
meter sounds at the same time. |
(h)After the buzzer sounds, if the engine switch is pressed within 5 seconds with the brake pedal not depressed, the power source mode changes to on (ACC) or on (IG), the same as in the normal condition.
7.DIAGNOSIS
The main body ECU can detect malfunctions in the pushbutton start function when the power source mode is on (IG). When the ECU detects a malfunction, the amber indicator light of the engine switch flashes to warn the driver. At the same time, the ECU stores a 5-digit DTC (Diagnostic Trouble Code) in the memory.
•The indicator light warning continues for 15 seconds even after the power source mode is changed to off.
• The DTC can be read by connecting the intelligent tester |
ST |
to the DLC3. |
•The push-button start function cannot be operated if a malfunction occurs.

HOW TO PROCEED WITH TROUBLESHOOTING
HINT:
• Use the following procedures to troubleshoot the pushbutton start function.
• The intelligent tester should be used in steps 4, 5 and 8.

2 CUSTOMER PROBLEM ANALYSIS CHECK
HINT:
• In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.
|
• Gather as much information as possible for reference. |
|
|
Past problems that seem unrelated may also help in some |
|
|
cases. |

(a)Turn the engine switch on (START) and check that the engine starts normally. Make sure the brake pedal is depressed and the shift position is P at this time.
(b)Check that the engine switch mode can be changed by pushing the engine switch.
HINT:
Without depressing the brake pedal, push the engine switch repeatedly. Engine switch mode should turn from off to on (ACC) to on (IG) and back to off.
With the brake pedal depressed, push the engine switch repeatedly. Engine switch mode should turn to ENGINE START from any status.
OK:
Engine can start normally.

HINT:
Connect the cable of the intelligent tester to the DLC3, turn the engine switch on (IG) and attempt to use the tester. If the display indicates that a communication error has occurred, there is a problem either with the vehicle or with the tester.
•If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the original vehicle.
•If communication is still not possible when the tester is connected to another vehicle, the problem may be in the tester itself. Consult the Service Department listed in the tester's instruction manual.
3.INSPECT BATTERY VOLTAGE Standard voltage:
11 to 14 V
If the voltage is below 11 V, recharge or replace the battery before proceeding.

DATA LIST / ACTIVE TEST
1. READ DATA LIST
HINT:
Using the intelligent tester to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful as intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the DATA LIST information early in troubleshooting is one way to save diagnostic time.
(a) Connect the intelligent tester (with CAN VIM) to the
|
|
|
|
DLC3. |
|
|
|
|
|
|
When using the intelligent tester with the engine |
||
|
|
|
|
switch off, turn on and off any of the door courtesy |
||
|
|
|
|
light switches repeatedly at 1.5 or less second |
||
|
|
|
|
intervals until communication between the tester |
||
|
|
|
|
and vehicle starts. |
|
|
|
|
|
(b) Turn the engine switch on (IG). |
|||
|
|
|
(c) Enter the following menus: DIAGNOSIS / |
|||
|
|
|
|
ENHANCED OBD II / DATA LIST. |
