Diagnosis Description
INFOID:0000000001606869
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
.
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.

If the on board self-diagnosis does not start up, check the following items.
ERASING ON BOARD SELF-DIAGNOSIS
1.
Stop the vehicle and turn ignition switch OFF.
2.
Start engine and start on board self-diagnosis.
3.
During on board self-diagnosis, press CANCEL switch 5 times,
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.
CONSULT-III Function (ICC)
INFOID:0000000001606870
DESCRIPTION
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-35, "Diagnosis Description"
Unified meter and A/C amp. malfunction.
Inspect the unified meter and A/C amp. power and ground
circuits. Refer to
MWI-50, "UNIFIED METER AND A/C
Communication error of the combination
meter and the unified meter and A/C amp.
Start up the self-diagnosis of the unified meter and A/C
amp. and check the self-diagnosis results. Refer to
.
ICC steering switch malfunction.
Perform the inspection for DTC “OPERATION SW CIR
[C1A06]” (DTC 6). Refer to
.
Harness malfunction between ICC steering switch and ECM.
ECM malfunction.
ICC sensor integrated unit malfunction.
• Inspect the ICC sensor integrated unit power and ground
circuits. Refer to
• Perform the self-diagnosis for the ICC sensor integrated
unit with CONSULT-III, and check the diagnosis results.

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
→
1
→
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
0
