FUEL SYSTEM

FAIL-SAFE MODE

Mode

Description

Symptom

Possible Cause

MODE 1

FORCED ENGINE SHUTDOWN

Engine stop

• ETC system can’t proceed

reliable algorithm procedure
-

Fatal PCM internal
programming error

-

Faulty intake system
or throttle body

MODE 2

FORCED IDLE ＆ POWER

MANAGEMENT

Forced idle state controlled by
fuel quantity regulation and
ignition timing adjustment

• ETC system can’t control

engine power via throttle
device

• Disabled throttle control

or broken throttle position
information

MODE 3

FORCED IDLE

Forced idle state and no
response for accelerator
activation

• No information about the

accelerator position
-

Malfuctioning APS 1 and
2, faulty A/D converter
or internal controller

MODE 4

LIMIT PERFORMANCE ＆

POWER MANAGEMENT

Engine power is determined by
accelerator position and idle
power requirement (Limited
vehicle running)

• ETC system can’t securely

control engine power

MODE 5

LIMIT PERFORMANCE

1.

Engine power varies with
accelerator position, but
driver perceives lack of
engine power.

2.

MIL ON (Normal vehicle
running)

• Not reliable accelerator

position signal or bad
maximum power generation
-

Faulty APS, ignition
voltage or internal
controller

MODE 6

NORMAL

Normal

COMPONENT INSPECTION

THROTTLE POSITION SENSOR (TPS)

1.

Connect a scantool on Diagnoisis Link Connector
(DLC).

2.

Start engine and check output voltages of TPS 1 and
2 at C.T and W.O.T.

TPS 2

C.T

0.25 ~ 0.9V

Min. 4.0V

W.O.T

Min. 4.0V

0.25 ~ 0.9V

3.

Turn ignition switch OFF and disconnect the scantool
from the DLC.

4.

Disconnect ETC module connector and measure
resistance between ETC module terminals 4 and 1
(TPS 1).

5.

Measure resistance between ETC module terminals
7 and 6 (TPS 2).

ETC SYSTEM INITIALIZATION

1.

Erase DTC(s) memorized in PCM with a scan tool.

2.

Turn ignition switch off and wait for about 10 seconds.

3.

Turn ignition switch on for more then 1 second. (At this
time, the PCM records initial position of ETC motor on
its EEPROM).
