Fault-Tracing Information

Fault-tracing

Fault-tracing information
Use the following information and general checks during fault-tracing.

Note! Check that the fuses are intact. For locations, see the instruction manual, cover for fuse box, fuse ratings or similar.

1. Check, if possible, relevant functions in the vehicle using buttons/controls/test drives to determine the status of the fault.

Note! If the vehicle does not show any of the given symptoms in the diagnostic trouble code information (DTC), this may mean that the fault is intermittent or that the control module is not detecting the fault at this moment.

2. Use the diagnostic trouble code's frozen values, status identifiers and counter to determine the operating conditions when the fault was detected, the fault's current status and any degree of intermittence of the fault.
3. Check and fault-trace according to the fault causes that are specified in the diagnostic trouble code (DTC) information.
4. Use VIDA Vehicle communication. Read off the parameters, activate components and functions, carry out quick tests and checking routines for the diagnostic trouble codes to identify the fault.
5. Check relevant components according to Component specifications.
6. Check relevant signals using wiring diagram, signal specification and breakout box.

Note! More information is available in Design and function.

Remedy as necessary.

Information





Diagnostic trouble code (DTC) information CVM-U002800

Condition
The control module checks the communication with Supplemental restraint system module (SRS).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- No communication with the Supplemental restraint system module (SRS).
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- The voltage supply to the control module is 9-16 V.
- Ignition switch position II.

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 on one or both CAN cables on sensor CAN.

Fault symptom[s]
- Text window and warning symbol/Red symbol and text message
