DIAGNOSIS SYSTEM (ICC SENSOR INTEGRATED UNIT)

Diagnosis Description

INFOID:0000000000965393

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 BAOAD SELF-DIAGNOSIS SYSTEM DIAGRAM

ON BOARD SELF-DIAGNOSIS OPERETION PROCEDURE

1.

Turn ignition switch OFF.

2.

Start engine.

3.

From 5 seconds through 15 seconds after start engine, press
RESUME/ACCELERATE switch 5 times, and SET/COAST
switch 5 times.
NOTE:
• Never turn the MAIN switch ON.
• When operation above is not completed from 5 seconds

through 15 seconds, start again from above go to 1.

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-91, "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.

and DISTANCE switch 5 times in this order.
NOTE:
• Press them within 10 seconds after pressing CANCEL switch

at first.

• When operation is not completed within 10 seconds, start

again from step 2 above.

4.

DTC 55 will be shown.
NOTE:
DTC of an existing malfunction will not be erased.

5.

Turn ignition switch OFF to exit the diagnosis.

: 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-91, "DTC Index"

.

NOTE:
“DTC RESULTS” and “TIME” are indicated on “SELF-DIAG RESULTS”. “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])
