Two common ways to reboot are: (1) remove battery ground cable from battery post for 20-30 minutes, or (2) remove ground cable and press and hold brake pedal down for several seconds. A failing BCM can cause all sorts of problems including - unwanted security alarms (horn and lights), cycling door locks, run-away odometer, and other equally ugly symptoms.Ī few owners have had results (short-term) by rebooting the BCM.
This is why I suggested you make sure the basic electrical system is operating as expected.Īnother item which can directly affect both IPC and EPS is the body control module (BCM).
Keep in mind all vehicle grounds are common to the battery ground post. You'll note they're widely separated and so I'd think chasing individual grounds is not a good use of time. See the attached diagram for ground locations - item 7 is for instrument panel cluster (IPC) ground and item 12 is for electric power steering (EPS). No i am NOT replacing my engine, i simply dont know which ground cable location would be the one affecting my cluster and power steering to turn off and yes the problem only occurs when vehicle is moving and everything returns to normal when i stop/park, There'll be a smaller red cable between the battery positive terminal and the under-hood fuse/relay box (UHFB) - connected at windshield end of UHFB.Ĭould you clarify that problem only occurs while underway? That things return to normal when you stop/park? I believe I'd start at the battery connections - making sure the positive and negative cables are clean and tight.įollow the large red and black cables from battery to eventual destination to verify all connections are clean and tight. When this happens, they’ll need to be replaced.Sorry for activating a thread but, i have the same vue the 02 vue with a five speed and a 2.2 ecotec engine, i seem to be having a ground problem, would you happen to know which ground would cause my gages to turn on and off and at the same time turn my service engine, ABS, service engine soon, and parking brake light to come and also make my power steering shut off, also this only seems to be happening when the day is really hot, and also when ever the car is at a still position everything goes back to normal thanks and again sorry Like all batteries, auxiliary batteries will eventually wear out or fail. The primary battery delivers voltage during cranking, and the auxiliary battery runs some or most of the car’s accessories. In these instances, the alternator is responsible for charging both the primary and the auxiliary battery. These are used to power other systems on the car that require 12 volts of power, and which the alternator is not capable of powering directly. There’s the primary battery under the hood, but there’s also an auxiliary battery. However, some vehicles (notably higher-end European imports) have more than one battery. All other power generated during operation to power the radio, signal lights, and other accessories comes from the alternator.
This battery’s job is simple – it provides the electricity needed to start the engine. It’s generally located under the hood, although some makes and models have the primary battery in the trunk, near the spare tire. The vast majority of passenger vehicles on the road today have only a single, large battery. Service type Auxiliary Battery Replacement
