Dodge Grand Caravan
On the 2012 Dodge Grand Caravan, the ABS code C212a-16 is “SYSTEM VOLTAGE LOW – CIRCUIT VOLTAGE BELOW THRESHOLD”. Which is saying there is low system voltage to the ABS Module. This can be the case of a battery that has low voltage, a failing alternator or a faulty ABS Module. So, first thing to do is check the charging system. There is a quick and easy test for this, with the use of a voltage meter. With the engine running (if you need to jump-start the vehicle, make sure to remove the jumper cables before testing), take a voltage reading at the battery terminals. If the voltage is not between 13.2-14.4v, or fluctuates in and out of this area, the Alternator will need to be replaced. If the Alternator passes this test, turn the engine off and wait 15min. Take another reading at the battery terminals, this time with the engine off. When the voltage is anything less than 12v, the battery may have a “bad cell” and is not accepting the alternator’s charge. If you do not have access to a voltage meter, most local “big chain” parts stores, like AutoZone, will run these tests for Free right in their parking lot. If the battery and alternator check good, suspect the ABS Module has failed and will need to be replaced.
