EPS AND ENGINE LIGHT ON

Which fuse box is this 60 amp fuse located in ? Under hood in engine bay ?

I see one 60 amp fuse in that fuse /relay box , EPS
60A
Electronic Power Steering (EPS) Control Module , Why is this an issue with Chevy HHR'S ? where did you read this ? Fuse's don't go bad an don't blow for no reason , fuse's blow because of a electrical short circuit . Somewhere the wiring that fuse is suppose to protect is touching ground - metal on the body of the vehicle or somthing with the electric power steering system is a miss.

Whay do you say this ,My battery seems to go out around the same time as the fuse? Have you replaced the battery when this fuse blows ?

You need to under stand the electronics involved , serial data networks specifically . With a module , the electronic power steering module in your case going off line because of that blown fuse ,will disrupt serial data communications . Modules won't talk , information from the BCM - body control module to the PCM/ECM engine computer for starting won't happen .

This is why the people that changed your starter did that , they have no clue what happens when you turn the key to start . Suggest you find a better class of technician to take your vehicle to.

Circuit Description
Moving the ignition switch to the START position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM) requesting engine start. The ECM receives a 12-volt signal from the park/neutral position (PNP) switch or clutch pedal start switch notifying that it is safe to start the engine. There is a splice on this circuit in the fuse block-underhood that supplies power for the CRANK relay coil. The starter relay coil control circuit is then grounded by the ECM closing the switch in the CRANK relay suppling 12 volts to the S-terminal of the starter. Ground is supplied through the engine block. For remote vehicle start (RVS) information refer to Keyless Entry System Description and Operation in Keyless Entry.

Sorry but your not as savy about your vehicle as you think .

The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.

EPS Motor
The EPS motor is a 12-volt brushed DC reversible motor with a 61-amp rating. The motor assists steering through a worm shaft and reduction gear located in the steering column housing.

eps ???? spell it out electric power steering (EPS) system ? The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, nor the EPS motor are serviced separately from each other or from the steering column. Ant EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.
The scan tool won't communicate with what ? The power steering control module , BCM or PCM/ECM .

ever get a full tune up in 15 years.
lost power is 99% of time just that, not doing service on car.
and is very common,.... so....did you?
spark parts and filters?
lost power can be misfiring or bogging,
misfire is violent and spark.
bogging (smooth) is loss of fueling.
stalling is same
if you cant save the stall with a fast right foot, it is usually loss of fueling.
say, bad fuel, out of fuel, wrong fuel (diesel)
or filter clogged, low fuel pressure. (forget EPS)
fix engine.
unless transmission was slipping what it, RPM rises car fails to move faster, that be SLIP.

Bad computer it sounds like, possibly just a bad ground wire

SOUNDS LIKE EITHER THE STARTER RELAY, OR THE SWITCH! I'D START WITH THE RELAY FIRST!

If it's only happening erratically (cold) your seem to be describing a faulty starter, or even ck the relay if avail. Starter, most probable.

Could be a high resistance connection between the battery and starter or on the earth strap from the battery or the earth strap from the engine to the chassis. Get someone to turn the engine over whilst measuring the voltage on the starter motor. If you can't do that then unbolt the earth straps from the chassis, clean with some emery or glass paper and grease before re-tightening. There are other possible causes but I have had this on a couple of occasions. Dave

Every morning at lunch time and evening my jeep won't start. It doesn't grind but the electrical goes crazy. After a couple of trys it finally starts. Help

My EPS on my mitsubishi colt 2006 stopped working about 8 months now, I changed the electronic box,but it started to work for ten minutes and then stopped.I carried it by some electricians and they put the computer on it, but it is not getting through.Could someone lend some assistance!!!!!!!!!!!!!!!!!!!!!!!!1
