known as Astra G- these vehicles come from 99 to 2005
Z18xe- Simtec71
Variants
- there are 2 main variants z18xe with simtec 71 and a newer version called simtec 71.1
- after 2003 the fan controller is different, use your Vin and program with GDS to update is the ecu version is wrong, there is no CAN setting for this and you will not find it in the Tech2 or tech2win,
Programming
Vehicle
Nissan Navara, D40 yd25ddt, DPF Light on. (read the whole story not the fault you think it would be!)
Symptom:
A client of ours had mentioned that the vehicle had poor fuel economy and came in for a service we had check a few items such as fuel pressure and the infamous engine breather this vehicle did not have a catch can. 2 weeks later the vehicles DPF light had come on, this is where that fun started to work out what fault codes where displayed and why this could have happened only 2 weeks after checking faults codes and couldn’t find any reason to use more diesel than normal.
*PROGRAMMING EBCM ON VE COMMODORES
EBCM Replacement
If the electronic brake control module (EBCM) is replaced, the following procedures must be performed:
EBCM Reprogramming, refer to Service Programming System (SPS).
EBCM Reprogramming
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,

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.
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.
