Hello, yes more than likely, the sudden Surge of power can cause a spike which can upset more sensitive pieces of equipment. Your local garage should be able to clear them for you.

SOURCE: Radio does not work.

what you need is the radio code to get rid of the error code just disconnect both battery cables touch them together for approx. 30 seconds reconnect cables turn on the radio it should read code there might be a credit card size card in the glove box with the radio code if not look for a sticker in the glove box this is your radio code if not then the radio has to be removed to get the radio seial# then call a honda dealer up give them this number and they can look it up or if your bought the car new call that dealer up they should have this in their history

SOURCE: 2000 Honda Odyssey. The passenger side

The driver's Multiplex Control System is a small computer that controls (among many other things) the dash lights brightness, ignition key interlock, shift interlock, and has a tie in to the brake light system and horn relay. It may be that this small computer malfunctioned and started the whole problem chain.

However, I note from the factory shop manual that if polarity is reversed on the shift interlock--it can be damaged. Reverse polarity will ruin the diode inside the shift interlock. This could have happened when you jumped the battery--a brief period of getting the cables and terminals mixed up could have done it.

Checking the shift lock solenoid can be done by removing the steering column upper cover. Disconnect the shift lock solenoid connector (2 terminals). Using long jumper wires, apply battery voltage to terminal 1 (yellow wire side) of the solenoid and ground terminal 2 (green wire side). Check that the shift lever can now be moved out of Park. NOTE: applying voltage in the opposite direction of that above will damage the diode in the solenoid and will probably ruin it. Remove your jumpers and shift back to park and check that the solenoid locks. If the solenoid does not work properly, it will need to be replaced. This involves removing the end of the transmission shift cable and is a complex job. Remember, no power to the solenoid equals a locked solenoid--it takes power to unlock it.

The Multiplex Control Unit has a self diagnostic feature which checks the computer itself and inputs to the computer. The computer check is called mode 1 and the input test is mode 2. The diagnostic trouble codes are outputted to the ignition key light and beeper.

To test, first confirm that all fuses are good, especially fuse 9 (10A) in the driver's under dash fuse box (left kick panel) and fuse 13 (7.5A) in the passenger's under dash fuse box (right kick panel). Then use a jumper wire (a wire with small alligator clips on each end works best) to jump the two leads of the multiplex test connector. (This is a light green 2 terminal connector dangling from the same wire bundle as the brake pedal switch connector.) Buckle the driver's seat belt (avoids nuisance beeps). Now turn the ignition switch to on. After about 5 seconds, the ignition key light should come on and the beeper should beep for 2 seconds then stop for .2 sec. then beep once for .2 seconds. This indicates that the system is in diagnostic mode 1.

If no diagnostic trouble codes (DTC's) are present, the key light and beeper will not blink/beep again. If there are codes: about one second after entering mode 1, the key light and beeper will indicate the DTC and repeat it every 3 seconds. If there are more than one, the system will indicate them in ascending order. The codes will be a light flash and beep so you will have to count the flashes/beeps to keep track. The codes range from 1 to 6. Code 3 (three flashes/beeps) indicates a problem with the multiplex control unit itself. Write back here for other codes or for questions about mode 2.

1998 expedition yesturday was low on fuel got gas drove with headlights on got 4 miles down road vehicle died thought was bad gas 3hrs later vehicle would run but abs light and brake light would flash


There is a problem in the electrics of the vehicle. First place to start is to check the alternator drive belt for condition and tension. Next place is the battery terminals and condition and tension . Third place is to have a load test done on the battery as it may have an internal short and drawing all the current from the alternator. In effect when you add power requirements ( park lights then brake lights then headlights) you are actually using more current than the alternator can supply to keep the engine system running.

Battery and abs light come on then car dies new battery and alternater


Take an have it checked for DTC'S - diagnostic trouble codes . Guessing an replacing parts isn't the way . The charging system on your vehicle is computer controlled by the PCM - engine computer,. Your best bet , take it to a qualified repair shop.

Yes, they can be related. If the PCM, (computer) did not have sufficient voltage it can throw all kinds of lights on. Shouldn't be anything to worry about. As soon as your vehicles PCM goes through a drive circle or two they should go off on there own.

Was fine started great then voltage hand went left abs light came on brake light came on dome lights came on head lights went off all panel lights went crazy blinking then jeep would not start without


Seems to be having problems with the alternator. Alternator itself can be bad, but also the voltage regulator, which sits inside the PCM (powertrain control module).
DonĀ“t continue using with battery voltage around the 10V, because it will ruin your battery as well. Completely charge the battery with an external battery charger and let the alternator be checked out first.

ABS light is on


Try unhooking the negative lead to the battery and leave it off overnight. Hook it back up and see if this resets the ECU.

The ABS,Brake Light,Battery light go on and off sporadically while driving.Does this indicate an Alternator failure or a sensor/computer problem?


yes it's most likely a alternator problem,usually the internal diode bridge breaks causing all lights you mentioned to come on,if this happens at a idle open the hood and remove green connector on alt.if lights go out you've found the problem

1987 Saab, battery problems or my own error?


If some internal light "went out" but the switch is still "on", that might do it.
Something could be shorted. Check power seats' wiring. Radio.
