one last question ,there is no other codes in any of the other car modules, did you run like a full test on all modules with your scanner and only srs codes came up correct ?

The codes that I received on the full scan were as follows 1. AAC-Air Conditioning DTC code is 919100 The current refrigerant level is outside the permissible range fault is stored & current. 2 ESP- Electronic stability program DTC code C221500 one or more signals sent from control unit ' A1 ( Instrument cluster)' via the can bus is implausible. 3. SRS- Supplemental restraint system DTC code B273513 The squib for pyrofuse 'On-board electrical network line' has a malfunction. There is an open circuit.

Chad
Did you have any luck getting a response to my question?
Regards John
Expert:  Chad Farhat replied 4 months ago.

hey john, i m sorry for the delay

DTC 919100 , you need to check Freon level, a/c gauges needed . while car running & ac on you should see . 30 to 50 psi on low side & 150 175 psi max on hogh side

for system to operate correctly, if you see, low side pass the 50 psi and high side is within specs, then you low on freon

the other codes , i cant pull up, I will opt out , maybe another expert

the other codes are not pulling up for me.

have you tried clearing these codes and see what comes back ?

Chad

Customer: replied 4 months ago.
Hi Chad I have tried clearing these faults but they are stored and current on the scan tool .
Chad try typing in DTC code 9CFE into your system it for some reason has the same description as " SRS- Supplemental restraint system DTC code B273513 The squib for pyrofuse 'On-board electrical network line' has a malfunction. There is an open circuit." I found this infomation on the web is there a link between these codes ????? If this is the case does the code refere to the pyrofuse on the Battery positive terminal ??? what procedure is there to first of all check is operation and then repair this.Regards John

Thank you
