The temperature display indicates single or multiple DTCs. If no DTCs are present, the indicator remains blank.

NOTE: If indicator segments A, C, D, E, G, K, with the AUTO indicator, or the A/C ON indicator are on at the same time, there may be an open in the common ground wire.

DTC (Driver's Temperature Indicator Segment)	Detection Item
A	Climate control unit internal error
B	Output shaft (countershaft) speed sensor signal error. Check for DTCs in the A/T system and go to the indicated DTC's troubleshooting. If no DTCs are found, replace the climate control unit
C	Engine coolant temperature (ECT) sensor signal error. Check for DTCs in the PGM-FI system and go to the indicated DTC's troubleshooting. If no DTCs are found, replace the climate control unit
D	Communication bus line error (bus-off)
