PINPOINT TEST A: B0001:11, B0001:12, B0001:13, B0001:1A

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the driver airbag stage 1 circuits for the following faults:

Resistance out of range
Unexpected voltage
Short to ground
Faulted driver airbag

If a fault is detected, the RCM stores DTC B0001:11, B0001:12, B0001:13 or B0001:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.

The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM . If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC . As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

Wiring
Connections
Clockspring
Driver airbag
RCM

1 - May set DTC
2 - Desired range

Normal Operation and Fault Conditions

The RCM monitors the driver front door and passenger C-pillar side impact sensors and circuits for the following faults:

Open circuit
Short to voltage
Short to ground
Faulted driver front door side impact sensor
Faulted passenger C-pillar side impact sensor

If a fault is detected, the RCM stores DTC B1414:11, B1414:12, B1414:13, B1419:11, B1419:12 or B1419:13 in memory and sends a message to the IPC to illuminate the airbag warning indicator.

Normal Operation and Fault Conditions

The RCM monitors the passenger front door and driver C-pillar side impact sensors and circuits for the following faults:

Open circuit
Short to voltage
Short to ground
Faulted passenger front door side impact sensor
Faulted driver C-pillar side impact sensor

If a fault is detected, the RCM stores DTC B1415:11, B1415:12, B1415:13, B1418:11, B1418:12 or B1418:13 in memory and sends a message to the IPC to illuminate the airbag warning indicator.

A short to ground on either impact sensor feed circuit sets DTC B1415:11 and B1418:11.
A short to voltage on either impact sensor feed circuit sets DTC B1415:12 and B1418:12.
A CMDTC for circuit short to battery (failure type: 12) can be set by a short to voltage on the return circuit of the impact sensor.
When the feed circuit of either impact sensor is shorted to voltage, an invalid data received fault (failure type :81) may also be present for both sensors.

PINPOINT TEST AK: BXXXX:2B (ANY BXXXX DTC (DIAGNOSTIC TROUBLE CODE) WITH A 2B FAILURE TYPE) SIGNAL CROSS COUPLED

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The RCM monitors all deployable device and sensor circuits for a signal cross coupled (short) between components. Signal cross coupled Diagnostic Trouble Codes (DTCs) are present when one or both circuits of a component are shorted to one or both circuits of another component. Signal cross coupled Diagnostic Trouble Codes (DTCs) do not set when the circuits of a single device are shorted together, a different DTC is present (for example, a DTC for circuit resistance below threshold). The RCM sends a message to the IPC to illuminate the airbag warning indicator. When a normal loop fault is present (one loop is either shorted to battery/ground, open circuit or low resistance), then signal cross coupled diagnostics are not active. Once the normal loop fault is repaired, the signal cross coupled diagnostics resume.

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The Belt Tension Sensor (BTS) operates in conjunction with the OCS . The OCS interprets a variable voltage signal provided by the Belt Tension Sensor (BTS) to identify the possible presence of a child safety seat in the front passenger seat. The voltage output of the Belt Tension Sensor (BTS) is proportional to the amount of tension applied to the sensor by the belt: no belt tension causes a low voltage (approximately 0.95 volt) to be output and high belt tension causes a high voltage (approximately 3.8 volts) to be returned to the OCSM .

The OCSM monitors the Belt Tension Sensor (BTS) and related circuits for the following faults:

Resistance out of range
Unexpected voltage
Short to ground
Faulted Belt Tension Sensor (BTS) (part of front passenger seatbelt buckle)

If a fault is detected, the OCSM stores DTC B0061:11, B0061:12, B0061:13 or B0061:64 in memory and sends a message to the RCM over the HS-CAN2 indicating that an OCS fault is present. Upon receipt of this message, the RCM sets DTC B00A0:09 and sends a message to the IPC to illuminate the airbag warning indicator.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
OCSM B0061:11	Passenger Seatbelt Tension Sensor: Circuit Short To Ground	A fault is indicated when the OCSM measures voltage below a predetermined threshold on the Belt Tension Sensor (BTS) signal circuit. An open Belt Tension Sensor (BTS) VREF circuit can also set this DTC .
OCSM B0061:12	Passenger Seatbelt Tension Sensor: Circuit Short To Battery	A fault is indicated when the OCSM measures voltage above a predetermined threshold on the Belt Tension Sensor (BTS) signal circuit. An open Belt Tension Sensor (BTS) return circuit can also set this DTC .
OCSM B0061:13	Passenger Seatbelt Tension Sensor: Circuit Open	A fault is indicated when the OCSM senses an open on the Belt Tension Sensor (BTS) signal circuit.
OCSM B0061:64	Passenger Seatbelt Tension Sensor: Signal Plausibility Failure	A fault is indicated when the passenger seatbelt is unbuckled and the OCSM measures voltage on the Belt Tension Sensor (BTS) signal circuit greater than the maximum voltage returned during normal sensor operation.

PINPOINT TEST BA: B00C2:11, B00C2:12

Refer to Wiring Diagrams Cell 46 for schematic and connector information.

Normal Operation and Fault Conditions

The Belt Tension Sensor (BTS) operates in conjunction with the OCS . The OCSM provides a reference voltage to the Belt Tension Sensor (BTS), which changes as it passes through the sensor, based on how much tension is applied to the seatbelt and Belt Tension Sensor (BTS).

The OCSM monitors the Belt Tension Sensor (BTS) reference voltage circuit for a short to voltage or a short to ground.

If a fault is detected, the OCSM stores DTC B00C2:11 or B00C2:12 in memory and sends a message to the RCM over the HS-CAN2 indicating that an OCS fault is present. Upon receipt of this message, the RCM sets DTC B00A0:09 and sends a message to the IPC to illuminate the airbag warning indicator.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
OCSM B00C2:11	Passenger Seat Occupant Classification Sensor 'C': Circuit Short To Ground	A fault is indicated when the OCSM senses a short to ground on the Belt Tension Sensor (BTS) reference voltage circuit.
