Does anyone have any knowledge of or experience with this code TMCD0013? The code is actually "THC_d0013 Battery Coolant Heater Malfunction" The first step in diagnostics listed in the service manual is to check your 12V battery, as this error code can be improperly set by a drop in the 12V battery voltage. Batteries more than 3 years old are often suspect. Beyond that, it's either a problem in the wiring harness (which is what your dealer was proposing to check next), a problem with the thermal controller (located in the right rear cargo area, and rarely at fault), or a malfunctioning battery coolant heater (most likely culprit, after the wiring and 12V system has been ruled out). |
