DTC P1682: Ignition 1 Switch Circuit 2

Circuit/System Description
There are 2 ignition 1 voltage circuits supplied to the engine control module (ECM). The first ignition 1 voltage circuit is provided by the powertrain relay, through a fuse. This ignition 1 voltage circuit supplies power to all the internal ECM circuits associated with the throttle actuator control (TAC) operation. The run/crank relay provides the second ignition 1 voltage circuit to the ECM, through a fuse. This ignition 1 voltage provides power to other internal ECM circuits, except those associated with TAC operation. The ECM continuously monitors the voltage level difference between the two circuits.


do you know how to test electrical circuits with a DVOM - digital volt ohmmeter ? Do you know what a wiring diagram is ?

SOURCE: 2003 Chevy Impala Service Traction Sytem show on Dash

I can't answer the question about the gas fumes, but I had the same problem last year with the "Service Traction Sysytem" message and the Trac and ABS lights coming on in my Impala. Mine turned out to be because of a bad wheel bearing, that was causing the ABS and traction system not to work. I'm not sure if you've experienced this, but another thing that would happen with mine was that I would go to brake and have a hard time depressing the brake pedal, almost like it was pushing back. That is the point when the Trac and ABS lights came on.

The torque converter clutch circuit may be at fault. The best way to determine the problem is to have a scanner/computer to read check engine codes.

Hello and welcome. the engine reduce power waraning is the key to the other problems. this is normally a problem with the electronic throttle system. the engine control module disables the traction control system when it detects a engine problem, in your case a problem with the electronic throttle system. you shouldnt drive with this concern. this is normally covered under the vehicles 100,000 mile warranty. you need to conteact your nearest dealer for help

{: ) Code P0010 refers to a fault at the Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit Bank 1. This code will set if the ECM (Engine Control Module) detects that the commanded state of the driver and the actual state of the control circuit do not match for greater than 3 s.
The service procedure requires close monitoring with a scan tool. Well it may be too technical for you, but simply put, it may require replacing the CMP actuator solenoid valve if it fails the component test. If the component is found to be okay, the circuit and wirings should be checked for possible shorts or open, and also the signal performance. If all circuit tests proved normal, a replacement ECM may be recommended.
If the engine light and code is consistently present, most likely it's the actuator solenoid valve. Check it out with your trusted mechanic. Goodluck.

Malibu hybird 2008 /service traction /engine power reduced


Your best bet would be to take it to a qualified repair shop. Special tool's and knowledge are needed . Scan tools , electrical diagnostic , service information . Your vehicle has a bunch of computers (control modules) C.A.N. cantroller area network serial data communication networks . Hi speed , med. speed , low speed . The power steering is electronic ,computer controlled , sensors on the steering shaft .With those light's lit , DTC'S - diagnostic trouble codes are stored etc... Plus there is a real chance of being electrocuted. High voltage !
