Normal Operation and Fault Conditions

To place the vehicle in ON mode, locate the passive key inside the vehicle and press the ignition switch once, for at least one second, without applying the brake pedal. When in ON mode, the BCM activates the integral run/start relay and provides a ground signal to activate the BJB run/start relay, which distributes fused voltage to various components. The integral run/start relay in the BCM receives voltage from high current BJB MEGA fuse 2 (125A). The BJB run/start relay receives voltage from the battery through the high current BJB . The BCM uses a Field Effect Transistor (FET) to control the relays.

To start the engine, locate the passive key inside the vehicle, position the selector lever into PARK or NEUTRAL, and press the ignition switch while applying the brake pedal. When the ignition switch is pressed, a voltage signal is sent to the BCM and PCM . When the BCM detects the ignition switch is pressed, it begins the key initialization sequence by activating the front PATS antenna and the keyless entry rear antenna. Once the PATS detects a valid passive key is present, the PCM supplies power and ground to the starter relay.



  DTC Fault Trigger Conditions


  DTC Description Fault Trigger Conditions
B108A:01 Start Button: General Electrical Failure Sets if the BCM does not receive any signal from the ignition switch.
B108A:24 Start Button: Signal Stuck High Sets if the BCM detects a short to voltage from the Start/Stop 1 input circuit from the push button ignition switch.
B1142:29 Ignition Status 1: Signal Invalid This DTC sets when the BCM does not receive a valid ignition signal during a BCM self-test.
B1310:14 Run/Start Control: Circuit Short to Ground or Open The BCM continuously monitors the control side of the run/start relay. This DTC sets if the BCM detects an open or a short to ground on the control circuit. The BCM uses a Field Effect Transistor (FET) to control the run/start relay. When this DTC sets, the control side of the run/start relay is disabled via the Field Effect Transistor (FET). Once the condition that caused the DTC to set is repaired, the BCM must pass a self-test in order for the DTC to clear and the system to resume normal operation.

Refer to Wiring Diagrams Cell 13 for schematic and connector information.

Normal Operation and Fault Conditions

When the ignition is placed in RUN mode, the BCM provides a ground for the coil (control) side of the run/start relay located in the BJB . The BCM monitors the run/start relay control circuit and sets a DTC if the circuit is shorted to voltage.



  DTC Fault Trigger Conditions


  DTC Description Fault Trigger Conditions
B1310:12 Run/Start Control: Circuit Short to Battery When this DTC sets, the control side of the run/start relay is disabled via the Field Effect Transistor (FET). Once the condition that caused the DTC to set is repaired, the BCM must pass a self-test in order for the DTC to clear and the system to resume normal operation.

B135C:11 and B135C:15


Refer to Wiring Diagrams Cell 128 for schematic and connector information.

Normal Operation and Fault Conditions

When steering wheel heat is requested, the HSWM applies voltage and ground to the steering wheel heating element (integral to the steering wheel). The steering wheel heating element draws between 1 and 10 amps of current depending on steering wheel temperature. The HSWM uses a sensor in the steering wheel (integral to the steering wheel) to maintain the heated steering wheel temperature. The HSWM is designed to remain on, heating the steering wheel and maintaining temperature until switched OFF on the FDIM or until the ignition is turned OFF.



  DTC Fault Trigger Conditions


  DTC Description Fault Trigger Conditions
B135C:11 Heater Element: Circuit Short to Ground This DTC sets when the heated steering wheel is commanded on and the HSWM senses current greater than 10 amps on the steering wheel heating element output circuit for greater than 80 ms, indicating a short to ground. This DTC also sets when the steering wheel heating element output Field Effect Transistor (FET) in the HSWM has a thermal failure. When this fault sets, the steering wheel heating element output is disabled until the ignition is cycled.
B135C:15 Heater Element: Circuit Short to Battery or Open This DTC sets when the heated steering wheel is commanded on and the module senses current less than 1 amp on the steering wheel heating element output circuit for more than 80 ms. This indicates a short to voltage, an open circuit or an open circuit in the heating element. When this fault sets, the steering wheel heating element output is disabled until the ignition is cycled.

U210A:11 and U210A:15


Refer to Wiring Diagrams Cell 128 for schematic and connector information.

Normal Operation and Fault Conditions

When steering wheel heat is requested, the HSWM uses a sensor in the steering wheel (integral to the steering wheel) to maintain the heated steering wheel temperature. The resistance of the sensor rises as the temperature falls and the resistance falls as the temperature rises. The resistance can vary from 3,384 ohms at 50°C (122°F) to 34,699 ohms at 0°C (32°F). The HSWM supplies a reference voltage and ground to the temperature sensor and monitors the voltage drop from the temperature sensor for controlling current flow to the heating element. The HSWM is designed to remain on, heating the steering wheel and maintaining temperature, until switched OFF on the FDIM or the ignition is turned OFF.



  DTC Fault Trigger Conditions


  DTC Description Fault Trigger Conditions
U210A:11 Temperature Sensor: Circuit Short to Ground This DTC only sets when the heated steering wheel is commanded on and the HSWM reads a resistance value less than 627 ohms on the heating element temperature sensor input circuit for greater than 1 second, indicating a short to ground. When this fault occurs, the steering wheel heating element output is disabled until the ignition is cycled.
U210A:15 Temperature Sensor: Circuit Short to Battery or Open This DTC only sets when the heated steering wheel is commanded on and the HSWM reads a resistance value greater than 670,000 ohms on the heating element temperature sensor reference circuit for greater than 10 minutes. This indicates a short to voltage, an open circuit or an open heating element temperature sensor.

H8   CHECK FOR CORRECT HSWM (HEATED STEERING WHEEL MODULE) OPERATION
  • Disconnect HSWM C2406 .
  • Inspect for the following and repair as necessary:
    • corrosion (install new connector or terminals - clean module pins)
    • damaged or bent pins - install new terminals/pins
    • pushed-out pins - install new pins as necessary
  • Connect HSWM C2406 .
  • Reconnect all other previously disconnected connectors. Make sure all connectors are seated and latched correctly.
  • Ignition ON.
  • Using a diagnostic scan tool, clear all HSWM Diagnostic Trouble Codes (DTCs).
  • Using a diagnostic scan tool, carry out the HSWM self-test.
  • Operate the system and determine if the concern is still present.

Is the concern still present?

Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new HSWM .
REFER to: Heated Steering Wheel Module (HSWM) (211-05 Steering Wheel and Column Electrical Components, Removal and Installation).
No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
