Nissan Qashqai srs airbag light flashing
Discussion
I have a problem with my Nisaan qashqai j10 2011, air bag light it started flashing so i scanned for codes, i got 3 codes, 2 x U1000 and DTCC12187
Body-BCM (body control module), 1 fault code, U1000 Fault in CAN Communication: Fault in communication circuit
Central control unit-IPDM/ER (Intelligent power distribution module engine room) 1 Fault code: U1000 fault in CAN Communication: Fault intimittent.
DTCs1
DTCC12187 - Can Communication fault with TCS (Traction control system),
Invalid source computer multiplex signals,
Intimittent.
I deleted the codes yesterday, the srs airbag light did not stop flashing, so i turned the key on and off 3 times for 5 seconds then on again to see the airbag light flash slower then off again then turned the engine on, the light went off i went for a drive but it came back on again, i've done this a couple of times today.
When i got back home today, i re scanned for for codes now i get no fault codes but the srs airbag light is again flashing, does any one know what the problem could be or what i should be looking at or testing.
I've posted some screen shots of the scan results, 3 from yesterday showing the fault codes and one from today showing no fault codes but the srs airbag light is flashing.

I fixed the problem with the srs airbag light, it was the clock spring at fault, when the car was stationary and idleing the light would be off but when the steering wheel was turned it would cause the light to come on, but there were no fault codes present when scanned.
I removed the clock spring to test with a multimeter, probes into the plug and a jumper connector across the two pins in the socket, when i turned the clock spring it would open circuit. So if you have a qashqai with a flashing srs airbag light but get no fault codes check and test the clock spring it maybe the cause.
