Hyundai i-30: SRSCM / SRS Control Module (SRSCM)
Components and components location
1. SRSCM (Supplemental
Restraint System Control Module)
|
|
Description and operation
• |
Supplemental Restraint System Control Module (SRSCM) determines whether
and when to deploy air bag module, seat belt pretensioner (BPT) and
emergency fastenig device (EFD).
|
• |
It supplies the air bag module with the power required to deploy the
module or the BPT and EFD.
|
• |
It also performs self-diagnosis function of the supplemental restraint
system.
|
Repair procedures
1. |
Remove the ignition key from the vehicle.
|
2. |
Disconnect the battery negative cable and wait for at least three minutes
before beginning work.
|
3. |
Remove the floor console.
(Refer to Body - "Floor Console Assembly")
|
4. |
Pull up the lock (A), of the SRSCM connector, then disconnect the connector.
|
5. |
Remove the SRSCM nuts from the SRSCM, then remove the SRSCM.
|
1. |
Remove the ignition key from the vehicle.
|
2. |
Disconnect the battery negative cable and wait for at least three minutes
before beginning work.
|
3. |
Install the SRSCM (A) with the SRSCM mounting nouts.
Tightening torque :
7.8 - 10.8 N.m (0.8 - 1.0 kgf.m, 5.8 - 7.2 lb-ft)
|
|
4. |
Connect the SRSCM harness connector.
|
5. |
Install the heater ducts and floor console.
(Refer to Body - "Floor Console Assembly")
|
6. |
Reconnect the battery negative cable.
|
7. |
After installing the SRSCM, confirm proper system operation :
•
|
Turn the ignition switch ON; the SRS indicator light should
be turned on for about six seconds and then turns off.
|
|
After replacing the SRSCM with a new one, the "Variant Coding" procedure must
be performed.
1) |
On SRSCM variant coding mode, the airbag warning lamp periodically
blinks (ON : 0.5sec., OFF : 0.5sec.) until the coding is normally
completed.
|
2) |
If the variant coding fails, DTC B1762 (ACU Coding Error) will
be displayed and the warning lamp will turn on.
In this case, perform the variant coding procedure again after
confirming the cause in "DTC Fault State Information".
Variant Coding can be performed up to 255 times, but if the
number of coding work exceeds 255 times, DTC B1683 (Exceed Maximum
coding Number) will be displayed and SRSCM must be replaced.
|
3) |
If the battery voltage is low (less than 9V), DTC B1102 will
be displayed. In this case, charge the battery before anything
else, and then perform the variant coding procedure.
DTC B1762 (ACU Coding Error) and B1102 (Battery Voltage Low)
may be displayed simultaneously.
|
|
