Re: SYS light (Jasin9687)
If "SYS" is displayed in the LCD section of the instrument panel cluster after the customer installs a new stereo, he will need to do the following:
1. Buy (2) 1 kilo-ohm 1/2 Watt resistors. [Radio Shack part # 271-023. They sell them as a 2-pack for 29 cents.]
2. Disconnect the negative battery cable.
3. Remove the receiver.
4. Connect one end of both resistors to ignition power. (Yellow wire in the car.)
5. Connect the other end of one resistor to the purple/white wire in the car.
6. Connect the other end of the second resistor to the grey/black wire in the car.
7. Cover all connections and completely cover the resistors.
8. Reconnect the negative battery cable.

I believe the light will go away, but until you clear the codes, there will be an error stored in the history....

Re: SYS light (Jasin9687)
I did this when I recently installed my head unit and it worked. It really is simple, just put the 2 resistors in, cover everything up, and put the dash back together. I did have the SYS light on for a day or so while waiting for my head unit, but as soon as I installed the resistors it went away. I don't know if there is a code stored, have to check that out today.

Oh, one other thing..... this problem only occurs for people with manual a/c controls I think..... you guys getting this code, is that what you have? Or do you have auto climate control?
