SAFETY BELT SYSTEM - PRINCIPLES OF OPERATION
| WARNING | After any crash, all of the following safety belt assemblies and attaching hardware must be inspected by an authorized dealer to verify correct function: Retractors Buckles Belt tension sensor (BTS) (if equipped) Front safety belt buckle support assemblies (slide bar) (if equipped) Safety belt shoulder belt height adjusters (if equipped) Child safety seat tether bracket assemblies Automatic locking retractor (ALR) feature for child safety seats (passenger seating positions only) |
If any safety belt assembly is damaged, does not operate correctly or does not pass all of the Functional Tests in the Diagnosis and Testing portion of this information, a new safety belt assembly must be installed. If any safety belt assembly attaching areas are damaged or distorted, the sheet metal must be restored to its original structural integrity and new safety belt assembly and attaching hardware must be installed. Failure to install new safety belt assemblies and attaching hardware may increase the risk of serious personal injury or death in a crash.
After any crash that results in deployment of the driver and/or front outboard passenger safety belt pre-tensioners, new driver and/or front outboard passenger safety belt systems (including retractors, buckles and height adjusters) must be installed. Failure to install new safety belt systems increases the risk of serious personal injury or death in a crash.
Principles of Operation
The Restraints Control Module (RCM) continuously receives/monitors all inputs from the following Supplemental Restraint System (SRS) components.
- LH front impact severity sensor (left frontal restraints sensor)
- RH front impact severity sensor (right frontal restraints sensor)
- Driver first row side impact sensor B-pillar (left side restraints sensor 1)
- Passenger first row side impact sensor B-pillar (right side restraints sensor 1)
- Driver second row side impact sensor B-pillar (left side restraints sensor 2)
- Passenger second row side impact sensor B-pillar (right side restraints sensor 2)
- Safety belt buckle switches (driver and passenger)
- Driver seat track position restraints sensor
- Occupant Classification System Module (OCSM)
If the RCM detects sudden vehicle deceleration and/or lateral deceleration based on all the information received from all sensors and switches and determines that deployment is required, the RCM sends voltage and current to deploy the appropriate air bag module(s), safety canopies, adaptive load limiting retractors and/or safety belt buckle pretensioner(s).
The RCM contains an internal sensor that detects vehicle rollover angles. If the RCM determines that a rollover condition exists and deployment is required, the RCM sends voltage and current to the safety canopies, safety belt pretensioner(s) and/or adaptive load limiting retractors.
During a frontal or side crash, the RCM may deploy the following SRS components, based on crash severity conditions.
- Safety belt retractor pretensioner(s)
- Safety belt buckle pretensioner(s)
- Safety canopies
- Seat side air bag(s)
- Driver/passenger dual-stage air bag (one or both stages)
The fact that the safety belt buckle pretensioners, adaptive load limiting retractors or air bags did not activate for both front seat occupants in a collision does not mean that something is wrong with the system.
The RCM performs a self-test of the complete SRS during each startup. If a SRS fault exists, the air bag warning indicator will illuminate and remain illuminated for the rest of the ignition cycle. In addition to the self-test at start up, the RCM continuously monitors all of its SRS components and circuitry for correct operation.
Normal Operation
The Instrument Cluster (IC) module will illuminate the air bag indicator continuously for 6 seconds after the ignition switch is placed in the RUN or ON position. If the Supplemental Restraint System (SRS) is fault free, the air bag warning indicator will turn off and remain off. If a fault is detected in the SRS, the air bag warning indicator will illuminate and remain illuminated for the rest of the ignition cycle. The Restraints Control Module (RCM) will communicate to the IC via the High-Speed Controller Area Network (HS-CAN). The IC will illuminate the air bag indicator based on messaging from the RCM or if there is no communication between the RCM and IC.
The Restraints Control Module (RCM) continuously monitors driver air bag stage 1 (driver frontal stage 1 deployment control) circuits for the following faults
- Resistance out of range
- Unexpected voltage
- Short to ground
If a fault is detected, the RCM will store DTC B0001:11, 12, 13 or 1A in memory and send a message to the Instrument Cluster (IC) to illuminate the air bag warning indicator.
The RCM monitors driver air bag stage 1 circuits for resistance and expects a normal resistance between 2 and 3.68 ohms.
If resistance is between 1.75 and 1.99 ohms or between 3.69 and 4.29 ohms, there exists a strong potential for an intermittent fault to occur (a DTC may or may not set).
The RCM will also set and store a DTC if the loop resistance is less than 1.74 ohm or greater than 4.3 ohms.

The Restraints Control Module (RCM) continuously monitors driver safety belt retractor pretensioner circuits (driver seatbelt retractor pretensioner deployment control) for the following faults
- Resistance out of range
- Unexpected voltage
- Short to ground
If a fault is detected, the RCM will store DTC B1211:11, 12, 13 or 1A in memory and send a message to the Instrument Cluster (IC) to illuminate the air bag warning indicator.
The RCM monitors driver safety belt retractor pretensioner circuits for resistance and expects a normal resistance between 1.7 and 2.78 ohms.
If a loop resistance is between 1.47 and 1.69 ohms or between 2.79 and 3.31 ohms, there exists a strong potential for a fault to occur (a DTC may or may not set). The RCM will also set and store a DTC if the loop resistance is less than 1.46 ohms or greater than 3.32 ohms.

DTC DESCRIPTION
Normal Operation - Restraints Control Module (RCM)
The Restraints Control Module (RCM) continuously monitors the input voltage for correct operation. If the RCM detects input voltage below 9.5 volts, it will store DTC U3003:16 in memory. If the RCM detects input voltage of 20 volts, it will store DTC U3003:17 in memory. If the RCM sets DTC U3003:16 or U3003:17, it will send a message to the Instrument Cluster (IC) to illuminate the air bag warning indicator.
Normal Operation - Occupant Classification System Module (OCSM)
The Occupant Classification System Module (OCSM) continuously monitors the input voltage for correct operation. If the OCSM detects input voltage below 8 volts, it will store DTC B1318 in memory. If the OCSM detects input voltage above 17.2 volts, it will store DTC B1317 in memory. If the OCSM sets DTC B1317 or B1318, it will send a fault message to the RCM. The RCM will then send a message to the IC to illuminate the air bag warning indicator.
Note. DTCs B1317, B1318, B1676 U3003:16 and U3003:17 can be set if the vehicle has been recently jump started, the battery has been recently charged or the battery has been discharged. The battery may become discharged due to excessive load(s) on the charging system from aftermarket accessories or if the battery has been left unattended with the accessories on.

| B1318 - Battery Voltage Low | If the OCSM detects voltage below 8 volts, it will set this DTC. |
DTC DESCRIPTION
The Occupant Classification Sensor (OCS) system is used to classify the front passenger seat occupant in the event of a deployable impact.
The Occupant Classification System Module (OCSM) monitors the pressure sensor and circuity for faults. If the OCSM detects a fault with the sensor or circuitry, it will store DTC B2290 in memory and send a message to the Restraints Control Module (RCM) which will store DTC B00A0:09 in memory and send a message to the Instrument Cluster (IC) to illuminate the air bag warning indicator.
The OCS system components (seat cushion foam pad, bladder with pressure sensor and OCSM) are calibrated to each other and are serviced as an assembly. The OCS system components are not to be installed separately. If a new OCS system component or seat cushion foam pad are needed, a new OCS system service kit must be installed as an assembly.
| Fault PID Description | Fault Trigger Condition |
|---|---|
| 2290_12_OD and 2290_12_CM - Passenger Seat OCS Sensor No. 1 Circuit Short to Battery | When the OCSM senses a short to voltage on the bladder pressure sensor circuits, a fault will be indicated. |
| 2290_13_OD and 2290_13_CM - Passenger Seat OCS Sensor No. 1 Circuit Short to Ground | When the OCSM senses a short to ground on the bladder pressure sensor circuits, a fault will be indicated. |
| 2290_15_OD and 2290_15_CM - Passenger Seat OCS Sensor No. 1 Internal Fault | When the OCSM senses an internal failure with the bladder pressure sensor, a fault will be indicated. |
FAULT PID DESCRIPTION
Note. Fault PIDs that end in OD indicate an on-demand status and are associated with on-demand DTC B2290. Fault PIDs that end in CM indicate continuous monitor status and are associated with continuous DTC B2290.
The Belt Tension Sensor (BTS) operates in conjunction with the Occupant Classification Sensor (OCS) system. The OCS system interprets a variable voltage signal provided by the BTS to identify the possible presence of a child safety seat in the front passenger seat. The voltage output of the BTS is proportional to the amount of tension applied to the sensor by the belt, no tension low voltage (approximately 0.95 volt), high tension high voltage (approximately 3.8 volts).
The Occupant Classification System Module (OCSM) monitors the pressure sensor, BTS and all circuitry for faults. If the OCSM detects a fault on any of the BTS circuits, it will store DTC B2909 in memory and send a message to the Restraints Control Module (RCM), which will store DTC B00A0:09 in memory and send a message to the Instrument Cluster (IC) to illuminate the air bag warning indicator.
The OCS system components (seat wiring harness, seat cushion frame, seat cushion foam pad, bladder with pressure sensor and OCSM) are calibrated to each other and are serviced as an assembly. The OCS system components are not to be installed separately with the exception of the BTS. If a new OCS system, OCS system component or seat cushion foam pad are needed, a new OCS system service kit must be installed as an assembly.
| Fault PID Description | Fault Trigger Condition |
|---|---|
| 2909_29_OD and 2909_29_CM - Front Passenger Side Belt Tension Sensor Short to Ground | When the OCSM senses a short to ground on the BTS circuits, a fault will be indicated. |

| 2909_28_OD and 2909_28_CM - Front Passenger Side Belt Tension Sensor Circuit Short to Battery | When the OCSM senses a short to voltage on the BTS VREF or signal circuits, a fault will be indicated. |
FAULT PID DESCRIPTION
Note. Fault PIDs that end in OD indicate an on-demand status and are associated with on-demand DTC B2909. Fault PIDs that end in CM indicate continuous memory status and are associated with continuous DTC B2909.
The Restraints Control Module (RCM) monitors air bag, air curtain/canopy, seatbelt sensor, seat track sensor and safety belt pretensioner circuits for a signal cross coupled (short) between circuits. If the RCM detects a short between the circuits of one device and another device, it will store a DTC for each of the signal cross coupled faults in memory and send a message to the Instrument Cluster (IC) to illuminate the air bag warning indicator. When a normal loop fault is present (one loop is either shorted to battery/ground, has an open circuit or has low resistance), then signal cross coupled diagnostics will not be active. Once the normal loop fault is repaired, then the signal cross coupled diagnostics will resume.

DTC DESCRIPTION
The Restraints Control Module (RCM) supplies the stability/traction control system with the yaw rate, roll rate, lateral and longitudinal accelerometer over a dedicated Controller Area Network 2 (CAN2) bus. If the RCM detects a fault with communications with the ABS module or CAN2 bus circuits, it will store DTC U0028:08 or DTC U0028:88 in memory.
The RCM will not request the Instrument Cluster (IC) module to illuminate the air bag warning indicator if either DTC U0028:08 or DTC U0028:88 is set. The air bag warning indicator will remain off if either of these DTCs are set.
- DTC U0028:08 (Vehicle Communication Bus A: Bus Signal/Message Failures) - When the RCM does not receive CAN2 bus messages from the ABS module for 5 seconds, a fault will be indicated. An open CAN2 circuit, incorrect installed ABS module or loss of power and/or ground to the ABS module can set this DTC.
- DTC U0028:88 (Vehicle Communication Bus A: Bus Off) - When the RCM detects the CAN2 circuits are shorted to ground, shorted to voltage or shorted to each other, a fault will be indicated.
The ABS module may set DTCs U0151 (Lost Communication With Restraints Control Module) and U0452 (Invalid Data Received From Restraints Control Module).
