Hmm... depends on year make n model of your vehicle, and it depends which display is reading it.... Dash, driver, info center, etc. Without further info on the car, it just means environmental Health Officer, which is not helpful, I know. Where is this code being displayed?

The compass direction will show CAL if it needs to be calibrated.

The key has a chip in it.. :Possibly you key has lost its code.. try another key.. If that does not work check for fuel flow and spark at the plug wires/spark plugs.

disconnect your battery for 30 mins. this should reset everything

CAL stands for Calibrate. The IPC (instrument panel cluster) needs to be recalibrated. This could becaused by a battery/power spike, which means the IPC will need to relearn default settings, or therecould be an underlying problem. Technician will need to hook it up to a computer to analyze problem,and relearn settings.

You did not align the Ignition SWITCH

If the instrument cluster is getting battery voltage, then this means that the instrument cluster needs to be replaced. Only availible at the dealer.

The California emmission has a federal warranty is 5yrs or 60,000 miles. So if the vehicle is beyond the time and miles. The emmission warranty does not apply .

the security on the radio has been tripped you need to take it to a GM dealer and have them run a code to unlock it CAL means calibrate
