This week started off as a cracker, had a WK Caprice come in with a Traction control light that was not working, when the button next to the shifter was depressed.
The operation of the VY commodore, when pressing the TRAC button the TRAC OFF should change in the instrument cluster similar to that when pressing the PWR button.
This vehicle did have traction control as the button was present and also the 6 pipes on the ABS pump block where present, but the TRAC button and accelerator retarder did not work, after setting up the Tech2 on to the vehicle, it was found that the Tech2 could not communicate as the coding was wrong, we then set up the scan tool for a commodore V6 and the Tech2 connected we found fault 62 RPM sensor error, checked the RPM and at idle it was 275RPM instead of 650RPM,

We at P & G just love finding new things and sharing them with the our clients.
Below is the Australian product recalls website, there are a few recalls that are listed as well as the main website to browse.

Vehicle
Ford Falcon, BA, 4.0l 6cyl, P light flashing after driving for a short period of time.
Symptom:
The vehicle would go into limp mode and the P or D light will flash, whilst driving the accelerator actuation is stuck in limp mode so 30 kmh is as fast as you can drive the vehicle.
Vehicle
Alfa Romeo, 156, 2.0l Twin Spark, Surging Idle and stumble on take off, (sometimes).
Symptom:
Surging Idle When engine has warmed up, Worse with Air conditioner turned on
The Vehicle had been bought to the workshop to find out why the Idle was so erratic, the vehicle had undergone a few repairs already such as new spark plugs, air mass meter and throttlbody clean and reset the idle adaptions. Knowing this we set out to figure out why this problem in these vehicle is a hard one to pin point.
when can i drive?
At least twice a week we are asked if a client can drive the vehicle with no registration to our shop for an inspection, but did you know all the rules that apply to getting a vehicle registered?
We found the RMS website link that allows you to drive your vehicle.
Reading the information in the PDF document will help when trying to determine the source of the fault, not necessarily is the catalyst at fault there are many variables.
The first three bullet points on the list would be the hardest to test as these require testing before and after the cat converter with 5 gas analyser, the time to set up a vehicle would be a challenge.
To add to this the disappointment when you realise it is a v6 or v8 engine, this makes the setup to the vehicle even harder.
Vehicle
Holden Cruize, 2009, F18D Engine
Symptom:
The vehicle shows a check engine light on the dash board, the fault code is p2096 the description is post catalyst fuel trim system low limit.
the driving technique to make the symptom reoccur is warm up the vehicle so both o2 sensors front and rear are ready to send signal back to PCM, drive for 5 mins and drive to 80 kmh and back off the accelerator this will see that the o2 sensor both reach 0.00v when the vehicle is stopped and back to idle the front o2 sensor will start to cycle again, the rear o2 sensor will be at 0.12v – 0.18v and steady generally the voltage will take a while to rise, back to normal of 0.76v which is in the normal range of operation.
after this the check engine light will not come on the dash board but the fault code p2096 will be set in the PCM, during the test drive if you clear and carry out the same road test it will also be set again as the issue is still the same. this method of testing was the only way I could reproduce the fault time and time again.
Vehicle
Holden Cruize, 2009, F18D Engine
Symptom:
The vehicle did not start since towed in, we had a look at the fault codes and identified the fault as a body control Module (BCM) fault
Vehicle
Volkswagon Golf 1KZ 2008, TSI BLG engine
Symptom:
Engine light on, and vehicle responsiveness a little slow
The Vehicle had been bought to the workshop to find out why the engine light is coming on, a quick scan revealed a 08213 error also known as p2105 fault intake manifold flap position sensor fault improbable.
Vehicle
Holden Astra, AH, 1.8l Z18XER
Symptom:
Engine light on, and stalling sometimes when stopping at traffic lights
The Vehicle had been bought to the workshop to find out why the engine light is coming on, a quick scan revealed a p2120 error.
