2007 SRX code C0550 and C0281

Martinmoerenhout · Sep 22, 2015

Hello, my name is Martin, living in the Netherlands and I own a 2007 SRX.
When I start the car several messages are displayed: service powersteering, service brakeassist, service stabilitrak.
The steering is heavier than normal.
When I drive approx 1 kilometer (engine right temperature) and I then restant the car the messages disappear and the steering is back to normal.

I have the codes C0550 and C0281 that indicatie a problem with the EBCM.
But when this part is broke why does the problem go after driving a kilometer?
I have a new battery installed and all masspoints cleaned.

Can someone help me? Thanks in advance!

Your DTCs are likely due to connection problems or loss of ground for the ECBM. These can be intermittent. Best check all ground connections and reset connectors at ECBM and ECM.

Thanks for your reaction Glake89.
All groundconnections have been cleaned.
How do you reset the connectors? Or do you mean disconnect, clean and reconnect?

disconnect, clean and reconnect- yes.

Did that work out for you? I'm getting the same codes on the same year SRX. Thanks

I'm also getting these codes as well C0281 C0550 P1793 P0017 (twice) crankshaft position cam shaft correlation bank 1 sensor B and P0523

523 is a short or open in oil pressure sensor circuit. 1793 is an invalid read from a wheel speed sensor, poor connection at TCM or bad TCM.
0017 is cam position bank 1 out of whack- may be early chain problem. 523 is also the oil sender. 550 and 281 are related, EBCM has likely lost its ground. In a nutshell, probably all are wiring problems.
