P0036
Packed the bonnet hinges and bonnet latch into the Commodore in the hope that I can find some time this arvo to give them a grit blast.

With all the starts I have been giving the Chev this week, I decided to disconnect the negative terminal and put the battery on trickle charge.

Yo!
This morning I swapped the fuel pump relay with one of the thermo fan relays and gave it a start. Buzzing as usual. I thought I would check fault codes...
P0036
P0056
P0463 and
P0483
...are all usual suspects, no problems there.
The interesting one is P0480...
Cooling Fan Relay 1 Control Circuit
Extract:
"The causes for this DTC may include:
- Faulty fan control relay 1"
Don't know B2aaa, but I think "B" is something to do with body control module (which is deleted). I know the low-speed thermo fan function is managed by the BCM, so there is every chance it is tied-in with P0480.
Video here...
After switching the car off I swapped the relays back again.
A few other things...
Coolant is below the top of the core.
