Normal Operation
A side air bag module provides protection of the thorax area (between the neck and abdomen) of the body, working in conjunction with the head protection provided by a safety canopy module. Refer to Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) .
The restraints control module (RCM) monitors the side air bag module circuits for faults. The RCM will set a DTC if a short to battery or short to ground fault is detected. The RCM will also set a DTC if the loop resistance is less than 0.9 ohm or greater than 5.0 ohms. The normal expected resistance range is 1.31 to 4.29 ohms. If a loop resistance is between 0.9 and 1.31 or between 4.29 and 5.0 ohms, a DTC may or may not set, yet there exists a strong potential for an intermittent fault. If the RCM detects one of the following faults on any of the side air bag circuits, it will store DTC B2295 in memory and send a message to the instrument cluster (IC) module to illuminate the air bag warning indicator.
| Fault PIDsa | Description | Fault Trigger Condition |
|---|---|---|
| 2295_24_OD and 2295_24_CM | Side Air Bag Circuit Resistance Low, Front Passenger Side | When the restraints control module (RCM) measures less than 0.9 ohm between the passenger side air bag module circuits, a fault will be indicated. |
| 2295_25_OD and 2295_25_CM | Side Air Bag Circuit Open, Front Passenger Side | When the RCM measures greater than 5.0 ohms between the passenger side air bag module circuits, a fault will be indicated. |
| 2295_26_OD and 2295_26_CM | Side Air Bag Circuit Short to Ground, Front Passenger Side | When the RCM senses a short to ground on either of the passenger side air bag module circuits, a fault will be indicated. |
| 2295_27_OD and 2295_27_CM | Side Air Bag Circuit Short to Battery, Front Passenger Side | When the RCM senses a short to voltage on either of the passenger side air bag module circuits, a fault will be indicated. |
| 2295_28_OD and 2295_28_CM | Side Air Bag Circuit Resistance Low, Front Driver Side | When the RCM measures less than 0.9 ohm between the driver side air bag module circuits, a fault will be indicated. |
| 2295_29_OD and 2295_29_CM | Side Air Bag Circuit Open, Front Driver Side | When the RCM measures greater than 5.0 ohms between the driver side air bag module circuits, a fault will be indicated. |
| 2295_30_OD and 2295_30_CM | Side Air Bag Circuit Short to Ground, Front Driver Side | When the RCM senses a short to ground on either of the driver side air bag module circuits, a fault will be indicated. |
| 2295_31_OD and 2295_31_CM | Side Air Bag Circuit Short to Battery, Front Driver Side | When the RCM senses a short to voltage on either of the driver side air bag module circuits, a fault will be indicated. |
a Fault PIDs that end in OD indicate an on-demand status and are associated with on-demand DTC B2295. Fault PIDs that end in CM indicate continuous monitor status and are associated with continuous DTC B2295.
