Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Can you get the ECM scanned for codes please?
Astra ECM failure is fairly common now.
Is yours auto or manual transmission?
Do you have a Holden dealer nearby?
I have fixed many like this, could be ECM, could be CAN-BUS wiring.
Could also be a relay in the engine bay fusebox.
Sounds like your immobilizer is not reading the key.
Your key does have a chip, or should have if it, if it is missing.
That could be why the immobilizer light is flashing when you turn the key on.
Has your mechanic replaced any parts yet?
Has your vehicle been looked at by a HOLDEN Technician as yet?
They have the all the correct tools for correct diagnosis.
What tool did your mechanic use for programming?
The lights you are referring to the RH side, which aren't lit in your pic, are for traction control.
I'm wondering why the engine light and immobilizer light are not lit in the tachometer, where the charge warning light and cooling module lights are?
Do you need any further help?
I hope my advice has been of assistance to you.
