2009年3月15日 · DTC C2318 does imply that 12V bus voltage is low, which may be due to a failing 12V battery. Since that is the cheapest and easiest item to replace, I'd suggest starting with that. However there is no guarantee that your car does not have a more serious problem. The brake actuator will probably cost in the low four-digits to replace. Good luck.

2018年5月20日 · C2318 - Transmission low voltage P3000 - got two of these, one on the HV ECU and another one I didn't catch the detail of - "low voltage" P0A81 - HV battery coolant fan low voltage Measuring the little 12v battery from the relay box gives me 12.08 volts with the car off. I didn't check with the car on.

2023年11月16日 · C2318 sets when the "transmission control module" sees less than 9.3V at the B+ terminal for more than 1 second. This system only engages or releases the parking pawl to prevent the car from moving. Slight chance that a very weak 12V battery could set this. There's a particular B+ wire for the TCM in the underhood fuse box that can corrode.

2010年10月26日 · Re: After Collision and Body Repair, No Start & Code C2318 Thanks for the suggestion. I currently have the following warning lights and codes: Red lettered “BRAKE†light is on all the time, no code. Brake fluid level is good. Any ideas? ABS light is on, code 42, could not get it to clear using the method found on the forum.

2018年8月27日 · The only codes are-- Transmission module- C2318 Climate Module- B1411, B1421 . It only has 111,230 miles on it. The 12 volt battery tests good until when the ice is on, it's only being supplied 12.5 volts.

c2318 My +B was 7.18 V which makes sense for the code given the manual says, "Terminal +B voltage of the transmission control ECU is 9.3 V or less for 1 sec. or more." Reading through this as well:

2019年1月23日 · C2318 is about low power supply voltage reaching the transmission control ECU (a grandiose name for the box that drives the motor that shifts you in and out of Park). That could suggest a 12 V battery issue (though not necessarily; it could also be something in the wiring bringing the supply to that ECU).

2022年7月11日 · Later that day, the sound and lights came on again, without AC on. I took it to Autozone, borrowed their diagnostic tool, and the codes C1241 (Low battery positive voltage or abnormally high battery positive voltage), C1353 (Increasing pressure solenoid malfunction FL), and C2318 (low voltage error) came up.
