Diagnostic Trouble Codes and Associated Procedures

Immoblilizer

1. Turn ignition switch to ON.

2. The MIL should illuminate.

3. Turn the ignition switch to LOCK.

4. Locate the data link connector (DLC) in the engine conpartment and install the Hi-Scan Pro Tool.

5. Turn the ignition switch to ON and record any Diagnostic Trouble Codes displayed by Hi-Scan Pro Tool.

6. Refer to Diagnostic Trouble Code Chart, for fault description and actions.

Refer to Hi-Scan Pro Tool Manual.

1) Refer to Emission Control System, Hi-Scan Pro Tool Manual.
2) If a detected fault remains for the first time for a time, it is stored as "not confirmed fault". If the fault is detected

again when it is stored as "confirmed fault". It is stored as confirmed fault and MIL is ON after two driving cycles.

3) The driving cycle is counted up ten senconds passed after ignition ON or "erased code" of Kia Power Scan Tool.
4) Not confirmed fault : If a detected fault remains for the first time for a time, it is stored as a temporary failure that

is "not confirmed fault".

5) Confirmed fault : If the fault is detected again at status whitch is stored as "not confirmed fault", it is stored as

"confirmed fault"

6) Before replacing ICU or ECU, perform "Before Servicing and "Normal Coding" procedure and recheck inkey

immobilizer system.

General Diagnostics and Test

System check

Step

Action

Normal results

1

● Observe "IMMO" indicator.
● Turn the ignition switch to ON.

"IMMO" indicator illuminates for approximately
two seconds and goes out.

2

● Turn the ignition switch to START.

Engine starts.

3

● Turn the ignition switch to OFF.
● Diagnostic antenna coil connector from ICU.
● Turn the ignition switch to ON.
● Observe "IMMO" indicator.

"IMMO" indicator blinks continuously (2Hz).

4

● Perforn limphome with original corrent PIN.

"IMMO" indicator blinks from 2Hz to 0.5Hz.

5

● Turn the ignition switch to START.

Engine starts.

FOR 0K2AC 67 7R0 ONLY, MUST WAIT FOR 10 SECONDS AFTER PERFORMING "ECM CHECK" WITH KIA
POWER SCAN TOOL, BECAUSE THE RELAYOF ICU IS RETURNED IN ORIGINAL POSITION AFTER
APPROXIMATELY 10 SECONDS. IF YOU START ENGINE WITHIN 10 SECONDS, THERE ISTHE POSSIBLE OF
NOT STARTING ENGINE OR OCCURRING ECU FAULT CODE.
