Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information SRS-U023500

Condition
The control modules in the vehicle send and receive information continuously on the vehicle's controller area network (CAN).
The Supplemental restraint system module (SRS) is the main system in a local network, sensor-CAN, that both transmits and receives information via a standardised serial communication protocol - CAN (Controller Area Network). The local network can have several different control modules connected (market dependent).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The Communication between the Supplemental restraint system module (SRS) and Closing velocity module (CVM) is missing.
- Incorrect value runs longer than 2.5 seconds.

Note! This fault code is set regardless of on which network the problem is located.

The control module's test for the diagnostic trouble code (DTC) starts when:
- Ignition on.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Substitute value
- None.

Possible source
- Open circuit or loose connection in the cable between the Supplemental restraint system module (SRS) and the Closing velocity module (CVM).
- Fault-trace in transmitting control module.

Fault symptom[s]
- EA, Text window and warning symbol/Red symbol and text message
- KT, Warning lights and chimes/Supplemental Restraint System (SRS) indication/no indication
