B210D-BATTERY VOLTAGE LOW

For a complete wiring diagram Refer to Section 8W.

When Monitored:
Engine running, during heated seat operation.
Set Condition:
This code is set immediately after the Heated Seat Module receives a low charging system voltage message over the CAN B Bus or detects voltage under 11.3 volts on the (A33) Fused B(+) circuit.

Possible Causes

CHARGING SYSTEM VOLTAGE LOW

(A33) FUSED B(+) CIRCUIT

HEATED SEAT MODULE

1.CHECK PCM FOR CHARGING SYSTEM DTC

Are there any Charging System DTC's set in the Powertrain Control Module?

Yes

(Refer to 8 - ELECTRICAL/CHARGING - DIAGNOSIS AND TESTING) for Charging System diagnostic procedures.

2.VERIFY THAT DTC B210D-BATTERY VOLTAGE LOW IS ACTIVE

Does the DTC B210D-BATTERY VOLTAGE LOW reset?

Yes

The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)

3.CHECK THE VOLTAGE ON THE (A33) FUSED B(+) CIRCUIT

NOTE: Check connectors - Clean and repair as necessary.

Is the voltage at the HSM connector the same as measured at the battery?

Yes

Replace the Heated Seat Module in accordance with the service information.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)

Repair the (A33) Fused B(+) circuit as necessary.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
