B1676 - FAULT CODE - OBD2

B1676 Code failures by brands

B1676 FORD, LINCOLN, MERCURY: BATTERY PACK VOLTAGE OUT OF RANGE

Description of DTC code B1676

The B1676 OBD2 diagnostic code is a specific code from the fabricator. This code is activated when the PCM (Powertrain Control Module) notices abnormal battery voltage. When referring to battery packs such as those installed in hybrid and electric vehicles, it is important to say the code seems to be related to low battery voltages, but it refers to failures or malfunctions in the ABS Brake System.

One of the requirements for ABS is that it must be supplied with a constant current or voltage that is maintained within allowable ranges. It reduces the possibility that systems such as Traction Control, Cruise Control, Stability Control, and other related systems will not be adversely affected.

In a properly functioning system, the voltage from the battery to the ABS Control Module remains relatively constant. Some minor changes in the current supplied to the ABS are persistent. If the PCM detects that the ABS Control Module has received a voltage less than 9V or greater than 19V for more than 8 consecutive seconds, this code will set.

Possible solutions of the DTC code B1676

To troubleshoot DTC B1676 OBD2, try this:

To initiate the diagnosis, consult the TSBs.
Use an automotive scanner and check if additional DTCs to B1676 are stored, especially those related to ABS Repair according to the order shown by the scanner.
Check the wiring, connectors, and other electrical components related to the Anti-lock Wheel System and related systems. Look for damage caused by burns or corrosion. If you detect such conditions, make the appropriate corrections. Keep in mind this is an electrical fault, so there are many components involved in this code.
