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.
