Note:

certain vehicles affected by the WVM-23 Service Program may also be affected by the WVU-31 ECM Reprogramming Service Program. Since the
WVU-31 PAK file includes the updates contained in the WVM-23 PAK file, only reprogram the ECM using the WVU-31 PAK file. When WVM-23
is performed in conjunction with WVU-31, labor time will be reduced by 0.4 hours on the WVM-23 claim, to adjust for overlapping reprogramming
labor.
