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
.
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.

CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
WORK SUPPORT
Assumed abnormal point
Inspection item
Combination meter system.
Combination meter malfunction.
Check that the self-diagnosis function of the combination
meter starts up. Refer to
MWI-38, "Diagnosis Description"
.

Cause of Auto-Cancel Display Item List
×
: 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
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
0
→

→
2...38

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
