All of the warning lights or certain specific lights? If you have multiple system failures, the first suspect is a failed charging system. Measure the battery voltage with the engine running. It must be between 13.75 and 14.75 volts. If it is low, have the charging system tested by your mechanic.
With low system voltage, many of the computers will not work properly. Knowing that, they will shut down, and turn on their warning light to tell you.
