ACC = Automatic Climate Control
3 = you have a total of 3 codes - namely 2,8 and 11.
Here is the table of ACC codes. Try to recalibrate the ACC system (press AUTO and OFF simultaneously with engine running) and see if the codes come back.
Fault Code Defective function/component Malfunction Tech2 Code
1 Control module Internal control module malfunction B1605
2 Cabin temperature sensor Open circuit or short to B+ B1350
2 Cabin temperature sensor Short-circuit to ground B1350
3 Solar sensor Open circuit or communication error B1340
4 Mixed-air temperature sensor, LH Open circuit or short to B+ B1345
4 Mixed-air temperature sensor, LH Short-circuit to ground B1345
5 Mixed-air temperature sensor, RH Short-circuit to ground B2345
5 Mixed-air temperature sensor, RH Open circuit or short to B+ B2345
6 Stepping motor, air-mixing flap, LH Open circuit, short to B+ or short to ground B2490
7 Stepping motor, air-mixing flap, LH Jammed flap B2496
8 Stepping motor, air-mixing flap, RH Loose flap B2295
8 Stepping motor, air-mixing flap, LH Loose flap B2495
9 Stepping motor, air-mixing flap, RH Open circuit B2290
9 Stepping motor, air-mixing flap, RH Short-circuit to ground B2290
10 Stepping motor, air-mixing flap, RH Jammed flap B2296
12 Stepping motor, air distribution flap Open circuit B2400
12 Stepping motor, air distribution flap Short-circuit to ground B2400
13 Stepping motor, air distribution flap Jammed flap B2406
14 Stepping motor, air distribution flap Loose flap B2405
18 Heat exchanger solenoid Open circuit, short-circuit to ground B2375
18 Heat exchanger solenoid Short-circuit to B+ B2375
19 Circulation pump Open circuit, short-circuit to ground B2380
19 Circulation pump Short-circuit to B+ B2380
20 Control voltage, fan Short-circuit to B+ B2425
20 Control voltage, fan Short-circuit to ground B2425
21 Direct current motor, air recirculation flap B+ open circuit or shorted to ground B2410
22 This fault code means the ACC software is corrupt, this will require reflashing by a dealer using tech2
Most ACC systems will work normally with this code.
23 Sensor ground Ground to sensors shorting to B+ B2945
