TEXT
CSC = Customer Symptom Code
DTC = Diagnostic Trouble Code
DESCRIPTION
When diagnosing Diagnostic Trouble Codes (DTC's) for the Brake Control System, a technician must always follow the complete diagnostic fault-tracing path in VIDA. VIDA always lists the "Possible Sources" of the fault. In cases where the Brake Control Module (BCM) is NOT listed as a possible source, VIDA has added this note:
We understand that BCMs are being replaced solely on the appearance of a DTC in this RTJ, without following the diagnostic path in VIDA.
The occurrence of any of the DTC's listed in this TJ is not conclusive proof that the BCM is defective. Similarly if none of the following DTC's is found, the BCM has no hardware defect and the BCM must not be replaced. Replacing the BCM without a proper analysis may cause repeat repairs and consequently decreased customer satisfaction .
A workflow chart has been created and should be used as a guideline (additional to VIDA) when diagnosing BCM DTCs. See Figure 1 below.
SERVICE
If the BCM is replaced, printed information from VIDA which shows an appropriate DTC is required. Use the 'print' function on the VIDA screen. Note that this printout must show the VIN (which must match the VIN on the warranty claim), the appropriate DTC, and the date, which must be near the QW90 repair date. All three of these requirements are circled in Photo 1 in the attachment.
S40 MY 04-, V50 MY 05-, C30 MY 07-, C70 MY 06-
The BCM may have a general hardware defect if any of the following conditions is true. Go to VIDA for fault tracing. Check the "Possible source" list. Replace the BCM only if proper fault tracing according to VIDA concludes that the BCM is faulty. - One or more of the following BCM DTCs is set:

S80 MY 07-, V70/XC70 MY 08-, XC60 MY 10-
The BCM may have a general hardware defect if any of the following conditions is true. Go to VIDA for fault tracing. Check the "Possible source" list. Replace BCM only if proper fault tracing according to VIDA concludes that the BCM is faulty.
- One or more of the following BCM DTC's is set:
B10DF046, C000101, C000201, C000301, C000401, C001001, C001101, C001401, C001501,

In all other cases, the BCM does not have a hardware defect and should not be replaced.
If any of the above conditions apply, VIDA Fault tracing procedures must still be followed to find the root cause. They are not proof in themselves that the unit is defective. However if "none" of the conditions above applies, the unit has no hardware defect and the root cause lies elsewhere.
If TMA requests that the BCM be returned, the VIDA printout must be returned with it. BCM's returned without this printed information, or, printouts which do not show applicable VIN and DTC's as indicated above, may result in a warranty claim debit by VCNA.
