Injector Bank #1 Malfunc-
tion - High Voltage
- Malfunction of injector (#1, #4, #3)
circuit (High): Short to Ground or to
Battery.
- Operating voltage: 6 ~ 18 V
- Check the injector bank #1: Short
and poor contact
- Check if the trouble recurs with the
injectors removed and the ignition
key “OFF”.
• If recurred, check the injector
and ECU wiring harness.
- Check if the trouble recurs while
installing the injectors one by one
with the ignition key “ON”.
• If recurred, replace the injector
(perform C2I coding after
replacement).
• Check the other injectors with
same manner.
- Check the ECU wiring harness.
• ECU pin #44 and #63
- Replace the ECU if required.

Wrong response from Im-
mobilizer (refer to immo-
bilizer section)
- The invalid key is inserted or no
communication between transpon-
der and immobilizer (no response
from transponder).
- Perform the immobilizer coding again.
- Check the ECU wiring harness.
• Check the ECU pin #34 for open
and short.
- Check the immobilizer unit for open and
short or check the supply voltage.
- Check the immobilizer antenna and
transponder for damage.
- Replace the ECU if required.
