DIAGNOSIS SYSTEM (ICC SENSOR INTEGRATED UNIT)

Diagnosis Description

INFOID:0000000003130032

The ICC system includes the on board self-diagnosis function that allows the technician to check for any trou-
ble codes on the ICC system display by operating the ICC steering switch. 

ON BOARD SELF-DIAGNOSIS SYSTEM DIAGRAM

ON BOARD SELF-DIAGNOSIS OPERATION PROCEDURE

1.

Turn ignition switch OFF.

2.

Start engine.

3.

Wait 5 seconds after starting engine, then within 10 seconds,
push up RESUME/ACCELERATE switch 5 times, and push
down SET/COAST switch 5 times.
NOTE:
• Never turn the MAIN switch ON.
• When operation above is not completed within the specified

period, go back to procedure 1 and do all over again.

4.

When the on board self-diagnosis starts up, the ICC system display shows DTC No. (1) at the set vehicle
speed indicator. Refer to 

CCS-85, "DTC Index"

.

NOTE:
• DTC will disappear after 5 minutes.
• When more than one malfunction is detected, a maximum of 3 code numbers can be stored; the latest

malfunction will be displayed first.

: Applicable

• Last five cancel (system cancel) causes are displayed.
• “CAUSE OF AUTO-CANCEL” displays times of ignition switch ON/OFF up to 254 maximum. 254 is kept

though the number exceeds 254. The number returns to 0 when detecting the same cancellation causes. 

SELF DIAGNOSTIC RESULT

For details, refer to 

CCS-85, "DTC Index"

.

NOTE:
“DTC RESULTS” and “TIME” are indicated on “Self Diagnostic Result”. “TIME” is used as a reference data of
diagnosis. It shows when malfunction is detected.
“TIME” shows the following.
• 0: malfunction is detected at present (from malfunction detection to ignition switch OFF).

CAN communication (U1000, U1010)

• 1 ~ 39: Displays when it is normal at present and finds malfunction in the past. It increases like

39 after returning to the normal condition whenever IGN OFF

ON. If it is over 39, it is fixed to

39 until the self-diagnostic results are erased. It returns to 0 when malfunction is detected again in the pro-
cess.
Other than CAN communication (other than U1000, U1010) 

• 1 ~ 49: Displays when it is normal at present and finds malfunction in the past. It increases like
