Caution: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless otherwise
noted.

lCheck starter wires
lCheck TCU wires (only for 5-
speed automatic transmission)
lCheck starter and TCU
lECU No.2 pin : check normal

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.

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)
