hi, new here, looking for some help. Girlfriend has a 11’ CRZ EX 6mt. The 12v battery died over winter. The car now has EPS issues and a 32-0C Battery Current Detect Circuit code. Nothing else. It has now power steering. After new 12v battery, the code still won’t clear, I replaced EPS module with an identical module, took the car for a drive, still nothing. Any help?
Thank you! Using an Autel btw.

Are you able to pull up the live data PID for battery current? Autel is usually pretty good with that. Might be worth checking the output of the battery sensor. Did the positive lead have a lot of corrosion on it?

Nevermind, the other guys are on the right track. It would have other codes associated with it in other modules.
Honda's own diagnosis is to clear codes and see if they come back; then check wire integrity to the EPS module.

EPS Fuse?

check for chewed wires in and around the EPS connections (pop the hood and look down just on the inward-side of the brake booster)

Fuse 2 under the hood was good and 11 and 22 also checked out

yes I was able to pull data, I got 0v output I believe at motor. Might have to double check that. Or for corroded/ compromised wires going to motor.

I know I gave it a quick “looks good” check. But it may be time to start ohm testing. Just seems coincidental

Go into the EPS subsystem on the Autel and print the data list/any codes?

32-0C is the only code. It will clear and immediately come back. I can pull a data list tomorrow

32-0C is battery current detect circuit.

The only troubleshooting step in the manual is check for loose terminals in the EPS control unit. If no poor connections are found, replace the EPS control unit.

EPS control unit is in the cabin mounted to the firewall above and to the left of the clutch pedal bracket. Has two connectors with some heavy gauge wires.

Update for anyone wondering. I’m thinking it was self-inflicted when I installed springs/dampeners/ sway bar I lowered the front subframe enough to pull a wire out of the connector on top of the motor. Easy fix thankfully as it just pulled apart easily. Lesson learned! Thanks for all the help!

Sounds like the time I lowered the subframe to install the Swaybar, except that space is sooooooo tight, I forgot that there was a third connector to plug in....got in the car, no power steering, lol. Glad it's intact and back on the road!
