If there is no port on the front of the radio, your vehicle does not have the option for an aux port.

there may be a problem with the key. take it to a dealer or a qualified repair shop.

charge the battery. disconnect the cables and hook it back up. you should be able to turn on the ignition key to clear out message. if that doesnt work you can plug in an odb reader and clear out the codes.

Have the drive line inspected for worn parts like CV axle joints.

Hi, This sounds like the servo has a problem check out all servo connections & look for any stains at joints, if nothing showing check electrical connections. Does the vehicle stop as good as it always has done? if so then probably just a dashboard fault. If your not happy to ignore the light recommend take to garage & get technician to check it out on their computer. Please give feedback Malcolm Campbell. [email protected] Thanks.

Factory anti-theft system or add on (aftermarket ) ?

ahhh the other could be's ===bad key--ignition switch--short in wiring--relay--battery -computer -alarm

Is it actually overheating? If not, could be a coolant temp sensor, which controls your gauge

I would first suspect the fuel pump. Do you hear it buzz on for a couple seconds with turning the key to ON, not start? It should come on for 2 seconds to prime the line with pressure to the engine. Do you hear it? Stand by the gas tank and have someone cycle the key to on if you need to. If you hear nothing from the tank, you need to investigate the fuel pump and it's circuit. There will be a fuse for the fuel pump, it is under the hood in the power distribution box-the fuse/relay block. The power for the pump goes from that fuse to the fuel pump relay (also in that fuse/block) and when the engine computer signals that relay on, the power goes through the relay and then directly to the pump in the tank. Try this test, if your pump doesn't work-test the FPR-to test if the relay is getting a signal from the computer: hold your finger lightly on the relay. now have a helper cycle the key again from off to on (not start). Every time the key is cycled you should feel the click of the relay energizing. If you feel it click and you checked the fuse and it is good, and you still have no pump coming on, then it is likely you need a new pump. Bang on the bottom of the tank, a couple of raps, then see if pump turns on. A failing pump can sometimes be turned on by jolting it like this, but it only works a time or two or three. So now what? If the pump is working and putting fuel to the engine, then check for spark at a spark plug. Usually a sudden no start means the engine has lost either gas or spark.

It is on the throttle body.

wheel speed sensor code. check the wires on both front wheel bearings. Most likely cause is a broken wire.

Does just the engine shut down or you loose all electrical? Have the codes read. Even if the light isn't on. History or pending codes.

The TCM is incorporated into the PCM

How do you know when the fans should or should not work ? The PCM - engine control module tells the fans when to work . A coolant temp. sensor inputs coolant temp info to the PCM . Fans can come on when the vehicle isn't running , depending on temp. The cooling fans are turned on by the PCM using three relays . You best bet would be to take your vehicle to a qualified repair shop . Relay Driven Dual Cooling Fan Diagnostics
