I would take the car to an autoparts store and have the battery condition and alternator output checked. Most parts stores will do this for free. Since the message displayed indicated an engine electrical problem, checking the battery and alternator output is a good start toward isolating the problem. The generation of this message indicates a possible problem in the starting/charging system and these areas would be a good originating point. Check that you have a good and clean engine ground and clean and tight battery connections. I find that electrical problems are the worst to troubleshoot and sometimes you find the problem simply by process of elimination and careful observation. Really sorry for your trouble and I hope this helped. Best wishes.

Have a 1989 Riviera. Diagnostics on the touch screen keep saying there is an engine electrical problem and to service the engine. Buick Dealer says I need a CDM Control Box which seems to be part of


No it is not the computer (ECM) Check again I can't find any CDM module in this year. The problem you have is caused by a defective dash display in most of the cars I've repaired with this problem, you can call one of the many online repair sites and talk to them about the problem and see what they think.

My '05 LeSabre warning light for check tire pressure came on. I checked all 4 tires and they each have 32# of pressure. How do I reset the monitor? No manual in the car. Thanks


make sure your spare is up to 32#'s pressure also , unless its one of the donut tires, turn ignition switch to on with engine off , press and hold GUAGE INFO button which is located to the left of the sterring column until TIRE PRESSURE messgage is displayed , press and hold RESET BUTTON for 5 seconds , TIRE PRESSURE RESET message should appear on display , release RESET button, a TIRE PRESSURE NORMAL message should appear on the display , after ressetting the Tire Pressure Monitor system it requires 30 minutes of straight driving to complete calibration process .
