Hi All,
I recently had my OEM Clockspring Fail and render my Steering Wheel Controls (Volume/Cruise/Horn) fail, which produced an airbag light.
Foolishly I replaced my Clockspring with a cheaper than oem Ebay replacement, as I could not source a genuine Nissan Clockspring.
After replacing the Clockspring I started experiencing VDC/Traction control issues, the Traction control would kick in intermittently when turning the wheel from left to right. I figured out that it was the Wheel Angle Sensor. Predictably, the cheap replacement Clockspring part failed altogether shortly afterwards.
I downloaded OBD Software (Nissan Datascan) to attempt to reset the steering angle sensor to 12 o'clock as I figured that when swapping the clockspring out, even with my best attempts to keep the wheel as straight as possible it may have cocked slightly either way whilst removing the steering wheel. I ran a reset which cleared the traction control issues.
I received a replacement clockspring yesterday and fitted this, ensuring the wheel was kept straight and all connections were carried over before reassembling. I also ran a reset on the wheel angle sensor after installation to be cautious and cleared any fault codes.
However I am still getting intermittent traction control intervention, nowhere near as bad as initially but enough to nearly cause me to lose control of the car, before eventaully the traction control and slip light are permanately switched on until the car is restarted.
I have pulled the below codes out of the ABS/ECU Units using my OBD Software
C1145 - YAW RATE SENSOR
C1143 - STG ANG SEN CIRCUIT
I am getting quite frustrated, therefore last night out of desperation I have ordered a genuine Nissan 350z Clockspring/Squib Assembly including another wheel angle sensor from Ebay (these have been taken from a 2005 350z and are known working parts) and I will swap these out when I receive these in the next couple of days to try these.
My question is, how does the steering angle sensor take it's readings? Does it sense the position of the clockspring or does it independently get it's readings of the steering wheel position via another method? The reason I ask is because before replacing the Clockspring I had no issues whatsoever with VDC/Traction Control or the Wheel Angle Sensor, so I wondered if the cheap Ebay Clocksprings are giving erratic readings to the Wheel Angle Sensor.
I also ran a OBD Data Logging test. I recorded the Values of the Engine RPM (To Ensure my test was valid) alongside the Steering Angle Sensor Values. Whilst turning the wheel from lock to lock twice, The steering angle sensor value stayed on 0, whilst I got true live data from the Engine RPM.
Again I did not have this issue before replacing the Failed Clockspring so my thoughts are that how can the Wheel Angle Sensor Circuit/Sensor be faulty along with the yaw rate sensor?
Any thoughts on this are much appreciated, otherwise it's off to Nissan.
Thanks
Ash
