9A1-58 RESTRAINT CONTROL SYSTEM

DTC Will Clear When
The “Driver Pretensioner Low " voltage comes to
specified voltage.

DTC Chart Test Description
Number(s) below refer to circled number(s) on the
diagnostic chart.
2. This test determines whether the SRS control unit is malfunctioning.
3. This test isolates the malfunction to one side of the driver pretensioner assembly yellow connector at the
base of the driver seat.
4. This test determines whether the malfunction is in “Driver Pretensioner High” circuit.
5. This test determines whether the malfunction is in “Driver Pretensioner Low” circuit.

Diagnostic Aids
An intermittent condition is likely to be caused by a short
to ground in the driver pretensioner assembly circuit.
Inspect circuits “Driver Pretensioner High” and “Drive
r
Pretensioner Low” carefully for cutting or chafing. If the
wiring pigtail of the driver pretensioner assembly is
damaged, the component must be replaced. A careful
inspection of “Driver Pretensioner High” and “Drive
r
Pretensioner Low”, including the driver pretensione
r
assembly pigtail is essential to ensure that the
replacement SRS control unit will not be damaged.

Scan Tool Data List
The Immobilizer Scan Tool Data List contains all
immobilizer related parameters that are available on
the scan tool. Use the Immobilizer Scan Tool Data List
only after the following is determined:
• The Immobilizer Controls - Diagnostic System Check is completed. • On-board diagnostics are functioning properly.
A scan tool that displays faulty data should not be used.
Use of a faulty scan tool can result in misdiagnosis and
unnecessary parts replacement.
Only the parameters listed below are referenced in this
service manual for use in diagnosis.
Scan Tool Data Definitions
This information will assist in immobilizer problems.
Always perform the Diagnostic System Check -
Immobilizer Controls first. The Diagnostic System
Check will confirm proper system operation.
Ignition Status
This parameter displays the state of the ignition switch
input to the ICU. On indicates the ignition switch is
turned ON position.
Transponder Key
This parameter displays the state of the transponder
key in the steering lock. Transponder Key 1 to 5
indicates a correctly programmed transponder key is
used. The number 1 to 5 indicates which transponder
key is used. Invalid indicates an incorrect key is in
used. Not Programmed Key indicates a non-
programmed new transponder key is used. No
Transponder Key indicates ICU does not recognize a
transponder key. Transponder Status
This parameter displays the state of the transponder
key in the steering lock. Correct Transponder-Key
indicates a correctly programmed transponder key is
used. Wrong Transponder-Key indicates an incorrect
key is in used. New Transponder-Key indicates a non-
programmed new transponder key is used. No
Transponder Detected indicates ICU does not
recognize a transponder key.
Transponder-Key 1 to 5 Status
This parameter displays the state of number of
programmed transponder key(s). Programmed
indicates transponder key 1 to 5 is correctly
programmed. The number 1 to 5 indicates programmed
order.
Security Code Programmed
This parameter displays the state of the security code
programming. Yes indicates a security code is correctly
programmed. No indicates a security code is not
programmed.

Security Wait Time
This parameter displays the security wait time length in
the ICU. Inactive indicates not in security wait time.
Time indicates under security wait time. This wait time
stage will prevent any further attempts to enter the
security code until the wait time has elapsed. The wait
time will increase each time an incorrect security code
is entered. Note that this parameter is not count
downed. It keeps displaying the same time until that
wait time has elapsed. The ignition switch must be kept
at ON position during the wait time period.
While Security Lock
This parameter displays the state of the security wait
time. Inactive indicates not in security wait time. Active

PIM Programming Procedure must be done
whenever any of the following condtions are met:
• Diagnostic chart instructs you to program PIM
• New PIM is installed
• PIM is reused that was rest in an original vehicle
ICU & PIM Programming Procedure must be done
whenever any of the following condition is met:
• New or resued ICU and PIM are installed at the same time
ECM & PIM Programming Procedure must be done
whenever any of the following condition is met:
• New or reused ECM and PIM are installed at the same time
ICU & ECM Programming Procedure must be done
whenever any of the following condition is met:
• New or reused ICU and ECM are installed at the same time (transponder key(s) also replaced)
ICU, ECM & PIM Programming Procdure must be
done whenever any of the following condition is met:
• New or reused ICU, ECM and PIM are installed at the same time (transponder key(s) also replaced)
Notice: During programming of the new transponder
key(s), an authentication code is programmed into the
transponder chip and it cannot be reprogrammed
again. When replacing both ICU and ECM at the same
time, a new authentication code to be programmed into
the newly installed ECM is based on information of
newly installed ICU. However, the transponder keys
cannot be reprogrammed therefore it must be replaced.
Do not replace the ICU and the ECM at the same time
to avoid needless transponder key(s) replacement
simultaneously unless complete damaging was
encountered (e.g. both modules cannot be
communicated with a scan tool).
