Entering the self-diagnostic mode
1. Push in and hold the “Change Indicator and Reset” knob.
2. Turn the ignition ON.
3. W hen the LCD odometer turns ON, release the “Change Indicator and Reset” knob.
4. Push in and release the “Change Indicator and Reset” knob three times in quick succession.
The meter cluster is now in “Self-diagnostic” mode.
NOTE: Steps 2-4 must be performed within 7 seconds.
The meter cluster will not enter “Self-diagnostic” mode if any of
the following conditions occur:
1. The “Change Indicator and Reset” knob is not depressed when the ignition is turned ON.
2. The “Change Indicator and Reset” knob is released within 600ms of turning the ignition ON.
3. The “Change Indicator and Reset” knob is not depressed and released three times within 7 seconds.

Self –diagnostic mode
LCD condition
• All LCDs are lit during the transition from self-diagnostic
decision mode to self-diagnostic mode
• The odometer/trip indicator scrolls throng its entire range
approximately once every 600 ms. All digits are lit (segment
check indication). This continues until the self-diagnostic
mode is terminated.

Meter and gauge indications
Meter and gauge indications with the change indicator and
reset knob on (self-diagnostic mode) are as shown in the
following table.




RTW 78ASF000101


Speedometer 100 kilometers per hour
Tachometer 3,000 rpm
Fuel gauge
Temperature gauge Mid-point on the dial

All indications return to zero when the change indicator and
reset knob is turned off.
The self-diagnostic mode and the self-diagnostic decision
mode are cancelled when the ignition switch is turned to the
OFF position. They also cancel when a speed pulse is sensed.
If either of the self-diagnostic modes are cancelled by turning
the ignition switch to the OFF position, the diagnostic unit
remains in the stand-by condition.
If cancellation occurs when a speed pulse is sensed, the unit
remains in the ordinary operating condition.

DTC B0002
Description
The electrically erasable programmable read only
memory (EEPROM) memorizes immobilizer security
code and transponder key information. If the ICU
detects immobilizer security code is not programmed
into the ICU, this DTC will set.
Condition for Setting the DTC • The ICU detects that the security code is not programmed.
Action Taken When the DTC Sets • The engine will fail to run if the fault occurs before starting the engine. Condition for Clearing the DTC
• A current DTC clears once ignition cycle has occurred without the fault recurring.
• A history DTC will clear after 50 consecutive ignition cycles, if the condition for malfunction is no
longer present.
• Use a scan tool to clear the DTC.
Diagnostic Aids • Non-programmed ICU sets this DTC.

11A-28 IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6)
DTC B0008
Description
When the ignition switch is ON, the ICU begins
authentication of the transponder key in the steering
lock through the antenna coil. Once the ICU transmits a
signal, the transponder must send back a specific
response signal. If the ICU receives a wrong response
signal from the transponder, this DTC will set.
Condition for Running the DTC • The ignition switch is ON.
Condition for Setting the DTC • The ICU receives a wrong response signal from the transponder key. Action Taken When the DTC Sets
• The engine will not start if the fault occurs before starting the engine.
Condition for Clearing the DTC • A current DTC clears once ignition cycle has occurred without the fault recurring.
• A history DTC will clear after 50 consecutive ignition cycles, if the condition for malfunction is no
longer present.
• Use a scan tool to clear the DTC.
Diagnostic Aids • If the transponder key or ICU is transferred (swapped) from another vehicle, this DTC will set.
