Circuit Description
The Air Bag telltale indicates the ready status of the inflatable restraint system. The telltale activates when a class 2 message, indicating an inflatable restraint malfunction, is received from the SDM. The telltale will also activate during a loss of serial data class 2 and during the instrument cluster bulb check.
Conditions for Running the DTC
The diagnostic test is performed on the Air Bag lamp circuit whenever the telltale is being bulb checked.
Conditions for Setting the DTC
DTC B1510 sets when the instrument cluster detects a malfunction with the AIR BAG telltale circuit during the IPC bulb check.
Action Taken When the DTC Sets
The cluster sends a class 2 message to the SDM identifing a lamp circuit fault. The instrument cluster does not request the chime to sound or activate the CHECK GAUGES telltale in the HUD (if equipped).
Conditions for Clearing the MIL/DTC
The IPC successfully completes an entire Air Bag telltale bulb check without detecting any failures.
Diagnostic Aids
The IPC will store the code as current only as long as the failure exists. An intermittent failure will be stored as a history DTC.
