HVAC Diagnostic Code Translation 90-96.
For 90-96 owners these are the codes you can read from your AC control panel.
To access these codes do the following procedure.
1. Press both fan(up and down)buttons together and hold them for roughly 5 seconds. This will display a 00 on the A/C control panel LCD.
2. Use the fan up and down buttons to select the desired code you wish to read.
3. After selecting the code press button in-between the fan controls. This will display the code information on the A/C LCD.
Here are the codes:
HVAC Diagnostic codes
0- System Faults
(one of these will be set if your air conditioning controls have an LED flashing)
00=No Faults
01= Temp Door Motor Circuit Fault
02= Temp Door Motor Circuit Fault
03 = Ambient Sensor Open
04 = Ambient Sensor Short
05 = In-Vehicle Temp Sensor Open
06 = In-Vehicle Temp Sensor Short
07 = Solar Load Sensor Open
08 = Solar Load Sensor Short
09 = Low Freon Detected
10 = UART Failure
1- Temp Setting 60F to 90F
2- In-Car Temp Sensor 10 = HOT -130 = 230 = COLD
3- Outside Temp Sensor 10 = HOT -130 = 230 = COLD
4- Sun Load Sensor Max light Max Dark
L98 38 183
LT5 115 -110 = 210
5- Ignition System Voltage 0 = 9 Volts -155 = 255 = 16 V
6- Engine Speed (RPM divided by 25)
7- Vehicle Speed
9- A/C System Mode
00 = OFF
01 = Re-Circulation
02 = A/C
03 = Bi-Level
04 = Heater
06 = Defrost
07 = Vent
10 = Manual Re-Circulation
10- Blower PWM 0 = 0 Volts 128 = 14 Volts
11- Program Number 00 = COLD -155 = 255 = HOT
12- Mix Number -155 = 255 = COLD 00 = COLD
16- Coolant Temperature In degrees C
17- Solar Correction 114 = Max light 128 = max dark
30- Stored Full Hot Value 0 to 50
31- Temp Door Travel Range 100 to 200
34- Temp Door Position Requested 00=Full HOT -153=253=Full COLD
35- Compressor On Time 0.1 second increments
36- Number Of Times Below Critical Time
37- Software Version Number
