Kia Cadenza YG: SRSCM / SRS Control Module (SRSCM) Repair procedures

Kia Cadenza YG 2016-2021 Service Manual / Restraint / SRSCM / SRS Control Module (SRSCM) Repair procedures

Removal
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 the Body group - console)
4.
After removing the bolt (A), remove the rear vent duct (B).

5.
Pull the lock (1) forward and the pull the lever (3) after pressing the lever lock (2).
Disconnect the SRSCM connector (A) and (B).

6.
Remove the SRSCM mounting bolts(3EA) from the SRSCM, then remove the SRSCM.
Installation
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 with the SRSCM mounting bolts.
Tightening torque :
8.0 ~ 10.0 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)

   
Use new mounting bolts when replacing the SRSCM after a collision.
4.
Connect the SRSCM harness connector.
5.
Install the rear vent duct and floor console. (Refer to the Body group - console)
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 go off.
Variant coding
After replacing the SRSCM, the “Variant Coding” must be performed.
   
1)
On SRSCM variant coding mode, the airbag warning lamp is periodically blinking (ON: 0.5sec., OFF: 0.5sec.) until the coding is normally completed.
2)
If the variant coding is failed, DTC B1762 (ACU Coding Error) will be displayed and the warning lamp will be turned 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.
Variant coding Procedure

    Components

    Description The front impact sensor (FIS) is installed in the Front End Module (FEM). They are remote sensors that detect acceleration due to a collision at its mounting location.

    Kia Cadenza YG 2016-2021 Service Manual: A/C Pressure Transducer Description and Operation

    Description A/C pressure transducer convert the pressure value of high pressure line into voltage value after measure it. By converted voltage value, engine ECU controls cooling fan by operating it high speed or low speed. Engine ECU stop the operation of compressor when the temperature of refrigerant line is so high or so low irregularl

    Kia Cadenza YG 2016-2021 Service Manual: A/C Pressure Transducer Repair procedures

    Inspection 1. Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals. 2. Inspect the voltage value whether it is sufficient to be regular value or not. Voltage = 0.00878835 * Pressure + 0.37081095 [PSIA] 3.
