Airbag Trouble Codes
The airbag control module may report any of the following diagnostic trouble codes. For the following codes, replace the control module (ACM)
even if set intermittently:
-
ACM ACCELEROMETER
-
ACM OUTPUT DRIVER CIRCUIT OPEN
-
ACM INTERNAL DIAGNOSTIC CODE #1
-
ACM INTERNAL DIAGNOSTIC CODE #2
-
ACM STORED ENERGY
-
ACM OUTPUT DRIVER
For these codes, refer to the appropriate diagnostic procedure:
See: Testing and Inspection
Cluster Message Mismatch
Driver Squib Circuit Open
Driver Squib Circuit Shorted
Driver Squib Circuit Shorted to Battery
Driver Squib Circuit Shorted to Ground
Loss of Ignition Run Only
Loss of Ignition Run/Start
No Cluster CCD Message
No CCD Communication
Passenger Squib Circuit Open
Passenger Squib Circuit Shorted
Passenger Squib Circuit Shorted to Battery

Enhanced Accident Response (Highline Only)
If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the CCD bus to the CTM module to unlock the doors. The
interior lights will be turned ON 10 seconds after getting zero speed message on the CCD bus.
In addition to unlocking the doors, the lock feature will be disabled for a predetermined amount of time following the deployment. Once the
ignition key has been cycled to the "OFF" position, normal operation will resume.
CENTRAL TIMER MODULE
The AB RAM VAN has two different body electrical systems, High Line and Base. The High Line utilizes a Central Timer Module (CTM) to
provide the body features listed below. The CTM was designed to reduce cost, wiring complexity, and improve the system reliable. The CTM
interfaces with other modules in the vehicle on the Chrysler Collision Detection (CCD) data bus network. The CCD data bus network allows the
sharing of information between modules and diagnostic capability using the DRBIII (R). The CTM equipped vehicles can be identified by the
sound of a Key-In Ignition CHIME.
The Base AB RAM VAN body system is composed of individual modules. Because the standalone modules do not communicate on the CCD Bus
they cannot be diagnosed using the DRB. For concerns about the BASE AB VAN, refer to the appropriate service Procedures. The Base version
can be identified by the sound of the Key-In Ignition BUZZER.
