9A1-68 RESTRAINT CONTROL SYSTEM

DTC B0061 (Flash Code 61) Warning Lamp Circuit Failure



RTW 79ALF000301

Circuit Description
W hen the ignition switch is first turned “ON”, “Ignition 1”
voltage is applied from the “METER” fuse to the “SRS”
warning lamp which is connected to “SRS" warning
lamp, terminal “4”. The “SRS” fuse applies system
voltage to the “Ignition 1” inputs, terminal “1”. The SRS
control unit responds by flashing the “SRS” warning
lamp 7 times. The SRS control unit monitors the “SRS
W arning Lamp" terminal "4" for conditions that are
incorrect for the commanded state of the "SRS" warning
lamp.
For example, a failure condition exists if the SRS
control unit detects low voltage when the "SRS" warning
lamp is commanded OFF, or high voltage when the
"SRS" warning lamp is commanded ON. If the SRS
control unit detects an improper voltage on the “SRS
W arning Lamp" terminal "4", DTC B0061 will set.
DTC Will Set When
The SRS control unit try to turn "ON" the "SRS" warning
lamp but the battery voltage is not supplied to terminal
"4".
The SRS control unit try to turn "OFF" the "SRS"
warning lamp but the battery voltage is supplied to
terminal "4".

Action Taken
If circuits of the “SRS" warning lamp power supply and
ground are normal condition, the SRS control unit turns
“ON” the “SRS” warning lamp and sets a diagnostic
trouble code.

11A-24 IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6)
DTC B0003
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 never receives a 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 does not receive a response signal from the transponder key.
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 • Electromagnetic interference may affect intermittent condition.
• An antenna coil problem may set this DTC.
• Objects that block transponder key in the steering lock may set this DTC.
• Another key that is attached to the key ring may affect this DTC to set.
• If the ignition switch has been turned ON without transponder key this DTC sets.

IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6) 11A-27
DTC B0007
Circuit Description
When the transponder key authentication is completed,
the ICU begins authentication of the ECM. The ECM
transmits a specific request signal to the ICU and the
ICU sends back a response signal to the ECM. Both
communication signals are carried out via a controller
area network (CAN) communication bus. If the ICU
does not detect a request signal from the ECM, this
DTC will set.
Condition for Setting the DTC • The ICU does not receive a request signal from the ECM.
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 • Electromagnetic interference may affect intermittent condition.
• If the ignition switch is cycled (ON > OFF > ON) rapidly, this DTC may set but engine starts. This is
normal and a current DTC clears once ignition
cycle has been normally occurred.

Resetting and Programming
Resetting and Programming Guidelines
Notice:The security information must be programmed
when the ICU, ECM, PIM or transponder key(s) is
replaced, or transponder key(s) is added.
Vehicle Security Information Card (If issued)
When performing ICU, ECM, PIM or transponder key(s)
resetting or programming functions using a scan tool,
you will be prompted to enter four digits of security
code (1). This information is found on the vehicle
security information card issued with the vehicle when
new. If the card is unavailable, contact a distributor’s
service department to obtain the relevant security code.
For new owners, distributor or dealership must provide
vehicle security information card that has identification
numbers of owner’s vehicle immobilizer system. This
information is very important in case of repair or
transponder key is lost. It is necessary to provide
following items in your responsibility.
• Vehicle security information card to a new owner.
• Blank vehicle security information card it is for reissue.
• Instruction to your dealership how to use it.
Your organization must keep security code for all
vehicles as confidential data. In case of vehicle security
information card is lost, the data can be requested from
a distributor’s service department. This request will only
be processed if accompanied by the enclosed form and
proof of ownership. Once the data is received, it can be
entered in a blank card and given to the customer. The
unused card should be destroyed. Instructions on filling
out the Data Request Vehicle Security Information Card
as follows.
• The data requested under items 1 to 10 must be provided completely, including the authorized
dealership number, the vehicle identification
number (VIN) and engine type/ number. • Complete the form by entering data and signature/
authorized dealership stamp and send it along with
proof of ownership to address provided in the form.
• The requested data will be sent by fax to dealership that made the request after your
organization has confirmed that the information is
correct.
Security Code
The security code is required when performing ICU,
ECM, PIM or transponder key(s) resetting or
programming functions. When a scan tool requests the
security code to be entered, and an incorrect code is
entered, the ICU, ECM or PIM will go into a security
wait time stage. This wait time stage will prevent any
further attempts to enter the security code until the wait
time has elapsed. Should a second incorrect security
code be entered after the initial wait time has elapsed,
the ICU, ECM or PIM will go into a second wait time
stage. The wait time will increase each time an
incorrect code is entered. When the correct code is
entered the wait time will rest back to its original value
of 10 seconds.
• Stage 1 = 10 seconds
• Stage 2 = 10 seconds
• Stage 3 = 10 minutes
• Stage 4 = 20 minutes
• Stage 5 = 40 minutes

IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6) 11A-45
Description and Operation
Immobilizer System Description
Legend1. Transponder key
2. ICU
3. Controller area network (CAN) communication bus lines 4. Anti-theft control unit (with anti-theft system)
5. Engine control module (ECM) (4JK1/ 4JJ1)
6. Powertrain interface module (PIM)
7. Engine control module (ECM) (HFV6)

The immobilizer controls engine starting along with the
engine control module (ECM). The main system
components are the ICU, the ECM, the PIM (HFV6)
and the transponder key. The immobilizer system is
activated (immobilized) by an incorrectly programmed
or non-programmed transponder key, the ICU or the
ECM. While this system is activated, the ECM controls
the fuel injection system and starter cut relay in order to
fail to engine running. A typical engine starting
sequence is below.
1. When the ignition switch is ON, the ICU begins authentication of the transponder key in the
steering lock. The ICU transmits a specific request
signal to the transponder key and the transponder
key sends back a response signal to the ICU. Both
communication signals are carried out via antenna
coil.
2. Because the anti-theft system alarms if a key or other methods unlock the door, when the
transponder key is correctly authenticated the ICU
transmits an alarm cancel (disarm) signal to the
anti-theft control unit. (With anti-theft system)
3. After the transponder key authentication is completed, the ICU begins authentication of the
ECM. The ECM transmits a specific request signal
to the ICU and the ICU sends back a response
signal to the ECM. Both communication signals
are carried out via a controller area network (CAN)
communication bus. 4. After the ECM authentication is completed, the
ECM enables engine running.
