Normal Operation

WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

The safety belt retractor pretensioners are activated by the Restraints Control Module (RCM) to remove excessive slack from the safety belt webbing when an impact exceeding preprogrammed limits is detected.

The RCM checks all of the safety belt retractor pretensioners for faults. If the RCM detects one of the following faults on any of the safety belt retractor pretensioner circuits, it will store DTC B2292 in memory and, depending on the fault, flash a Lamp Fault Code (LFC) on the air bag warning indicator.

Fault PIDsa Description Fault Trigger Condition
2292_24_OD and 2292_24_CM Pretensioner Circuit Short to Ground, Front Passenger Side When the Restraints Control Module (RCM) senses a short to ground on either of the passenger safety belt retractor pretensioner circuits, a fault will be indicated.
2292_25_OD and 2292_25_CM Pretensioner Circuit Short to Battery, Front Passenger Side When the RCM senses a short to voltage on either of the passenger safety belt retractor pretensioner circuits, a fault will be indicated.
2292_26_OD and 2292_26_CM Pretensioner Circuit Open, Front Passenger Side When the RCM measures resistance greater than 5 ohms between the passenger safety belt retractor pretensioner circuits, a fault will be indicated.
2292_27_OD and 2292_27_CM Pretensioner Circuit Resistance Low, Front Passenger Side When the RCM measures resistance less than 0.9 ohm between the passenger safety belt retractor pretensioner circuits, a fault will be indicated.
2292_28_OD and 2292_28_CM Pretensioner Circuit Short to Ground, Front Driver Side When the RCM senses a short to ground on either of the driver safety belt retractor pretensioner circuits, a fault will be indicated.
2292_29_OD and 2292_29_CM Pretensioner Circuit Short to Battery, Front Driver Side When the RCM senses a short to voltage on either of the driver safety belt retractor pretensioner circuits, a fault will be indicated.
2292_30_OD and 2292_30_CM Pretensioner Circuit Open, Front Driver Side When the RCM measures resistance greater than 5 ohms between the driver safety belt retractor pretensioner circuits, a fault will be indicated.
2292_31_OD and 2292_31_CM Pretensioner Circuit Resistance Low, Front Driver Side When the RCM measures resistance less than 0.9 ohm between the driver safety belt retractor pretensioner 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 B2292. Fault PIDs that end in CM indicate continuous memory status and are associated with continuous DTC B2292.
