Thats just telling u the temp outside on celcious and fahrenheit thats all.
it’s the codes for the ECC circuit, best bet is to bring it to a shop and
see if maybe it needs coolant in the ac system. If you’re also looking to
get to the obd codes, you have to push the outside temp button and change
to 01 with the lo or hi button, then again push the outside temp button.
I have the 148 and 32 codes …..and the A/C clutch not enguage…I try
hard to make it run and change the climate control and it’s never work…so
I make external connection for the clutch with saparate switch……I have
the repair manual for these models 🙂 the codes are the # that flash when
you press “WARM &OFF” all together
No, they are diagnostic codes. The temp is shown in the normal setting,
this is in diagnostic mode. The codes are no longer popping up after it
went through an auto shop to have it safetied and e-tested. It now gives
code 32, which I’m not sure off hand what it means.
