when switch knob (planger) is pressed by 3mm : ¥
- Each ends resistance value of the switch when
switch knob(plunger) is not pressed :
less than 200 mW
lWhen brake is applied :
ECU (ABS:No.14, ABD:No.48) terminal 11 - 14 V
or VBattery.
When brake is released :
ECU (ABS:No.14, ABD:No.48) terminal 0 V
lCheck battery voltage.
lResistance between ECU (ABD:No.28 & 29,
ABS:No.19) pins and battery negative terminal :
less than 20 mW
lResistance between ECU No.1 (ABS:NO.15) pin and
ignition terminal : less than 60 mW
lCheck that normal voltage is applied to ECU
(ABD:No.1, ABS:No.15) pin when ignition switch is
turned to "ON" or "OFF".
lCheck ABS fuses of 15A and 80A.
lReplace the ECU.
lCheck wire (ECU No.50) for open or loose contact.
lCheck connection between connectors.
lCheck relevant wires for open or short.
(When connector is removed)
lCheck voltage between ECU side ground (ABD:No.1,
ABS:No.15 pin) and acceleration sensor side ground
(ABD:No.1, ABS:No.15 pin / ECU side ABD:No.39,
ABS:No.30 pin)
(When connector is installed and power is applied)
- Voltage : less than 0.25 V
lCheck voltage among related terminals.
(When connector is installed and power is applied)
- Voltage between ECU (ABD:No.43, ABS:No.28 pin
and ABD:No.39, ABS:No.30 pin)
: 4.75 - 5.25 V
- Signal voltage between ECU (ABD:No.51,
ABS:No.10) pin and (ABD:No.39, ABS:No.30) pin
: 1.95 V - 3.45 V
(Measure it by laying acceleration sensor horizon-
tally and without external force)

IMMOBILIZER SYSTEM 9W-9
Check and Remedy when Engine Does not Start
Starter operates normally?
Ye s No
lCheck fuses (No. 8 and 27)
lCheck ECU and antenna power
ECU terminal
- No. 12 (Power)
- No. 11 (Ignition)
- No.5/10 (Ground)
lCheck battery voltage
lCheck battery wiring
lCheck signal wires between ECU
and antenna
- Immobilizer No.3 wire (0.5BY) =
ECU No. 14 pin (0.75BW)
:
Writing immobilizer code number
- Immobilizer No.4 wire (0.5Y) =
ECU No.13 pin (0.75Y)
: Reading immobilizer cod number
lCheck starter wires
lCheck TCU wires (only for 5-
speed automatic transmission)
lCheck starter and TCU
lECU No.2 pin : check normal
signal of the starter 1)
- Engine cranking voltage : 8-15V
lCheck engine speed sensor wires
and replace
lReplace immobilizer antenna
lReplace transponder and ECUNotice
1)
MSE ECU equipped vehicle is designed to
make fuel injection when the engine speed
for initial cranking is over 450rpm if there
are no start switch inputs in ECU No. 2 pin.
If transponder and ECU are replaced,
perform programming.

IMMOBILIZER SYSTEM 9W-11
Check and Remedy when Engine Does not Start
Starter operates normally?
Ye s No
lCheck fuses (No. 19)
lCheck ECU and antenna power
and solenoid valve
ECU terminal
- No. 9 (Ignition)
- No. 6 (Ground)
lCheck battery voltage
lCheck battery wiring
lCheck signal wires between ICU
and antenna
- Immobilizer No.3 wire (0.5Y) =
ICU No. 1 pin (0.75BW)
:
Writing immobilizer code number
- Immobilizer No.4 wire (0.5G) =
ECU No.3 pin (0.75Y)
: Reading immobilizer cod number
lCheck starter wires
lCheck TCU wires (only for 5-
speed automatic transmission)
lCheck starter and TCU
lECU No.2 pin : check normal
signal of the starter 1)
- Engine cranking voltage : 8-15V
lCheck engine speed sensor wires
and replace
lReplace immobilizer antennaNotice
2)
New valve is possible coded either with a
new ICU or an already used ICU. But old
coded valve is only possible coded with a
new ICU.
If transponder and ICU are replaced,
perform programming.
lReplace transponder and ICUlReplace the valve
1. Turn Ign sw ON
2. Turn Ign sw OFF & ON
(To learn the valve correctly it is necessary
to switch on Ignition twice for at least 5
seconds.)2)
