GENERAL DIAGNOSIS
Warning Lamp Check
As soon as the opening voltage is applied to the
sensing and diagnostic module (SDM) ignition input,
the SDM activates the warning lamp for a bulb check.
The SDM allows the lamp to blink at seven times for 7
seconds and then turn off.
During the bulb check, the SDM is not ready to detect
a crash or deploy the supplemental inflatable
restraints.

DIAGNOSTIC INFORMATION AND PROCEDURES
Fault Indication
The sensing and diagnostic module records the
system’s faults in two categories:
•
Active Fault
Current detected faults and the “C” appears the
first digit of the fault code on the scan tool display
(example: “C16”).
•
History Fault
These faults that were detected in the past, but are
no longer active. The “H” appears the first digit of
the fault code on the scan tool display (example:
“H17”).
Diagnosis by Using Warning Lamp
•
The warning lamp flashes for 7 seconds at seven
times and turn off : Normal Status - There is not
any history or current fault code.
•
The indicator turns on for 7 seconds and then turn
off : Normal Status - A fault has been detected
previously but now there is not any more of the same
detected fault. Clear the fault using the scan tool.
•
The indicator turns on for 7 seconds and turns off
for 1 second and then turn on again: Abnormal
Status - It has detected a current fault or has been
occurred same fault more than five times, or has
been occurred more than five types of faults. Perform
the diagnosis using the scan tool.
•
Warning lamp stays ON : Connection fault between
the SDM wiring harness connector and the SDM
connector, or the airbag wiring harness fault.
•
No the indicator turn ON : Power supply malfunction,
indicator circuit open, bulb fault, SDM internal
defect.
Diagnosis by Using Scan Tool
•
Check the fault code by connecting the diagnostic
(ALDL) connector.
•
Receive serial data from terminal 9 of the ALDL
connector.
•
Receive the ground signal from terminal 4 or 5 of
the ALDL connector.
Clearing Fault Codes
When the sensing and diagnostic module (SDM)
receives the “CODE ERASE” command from the scan
tool, the SDM:
•
Clears the entire fault memory.
•
Turns OFF the warning lamp.
•
When it is removed the scan tool after clearing the
fault code, the SDM rechecks the airbag system to
detect the SDM’s fault.
External Fault
Service personnel can reset the SDM and turn OFF the
warning lamp if the fault is an external fault.
Internal Fault
An internal fault of the SDM or a CRASH RECORDED
fault code cannot be reset.
In the case of an internal fault of the SDM or a CRASH
RECORDED fault code, the SDM must be replaced.
Microprocessor-Independent Lamp
Activation
If the sensing and diagnostic module (SDM) electrical
connector is not properly attached, the SDM cannot
function and cannot control the warning lamp.
If this fault is present, the warning lamp will operate
independently from the SDM through the use of shorting
bars that are built into the SDM connector.
Notice: Do not measure the resistance of the airbag
module because the multimeter’s battery may deploy
the air bag causing any personal injury.
