Possible cause<\/b><\/p>\n<\/td>\n

\n

NOTE:<\/span><\/b><\/p>\n

    \n
  • \n

    To correctly write the configuration data, which is sent from the instrument cluster to the connectivity master unit (CMU), to the connectivity master unit (CMU), 30 s or more<\/b> must have elapsed since the ignition was switched ON (engine off or on).<\/p>\n<\/li>\n<\/ul>\n

\n

1<\/p>\n<\/td>\n

\n VERIFY ALL SYSTEM DTCs<\/b><\/p>\n\n

Yes<\/p>\n<\/td>\n

\n

Using the M-MDS, perform the instrument cluster configuration (using As-Built data) again, then go to the next step.<\/p>\n

(See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA)<\/a>.)<\/p>\n<\/td>\n<\/tr>\n

\n

No<\/p>\n<\/td>\n

\n

Go to Step 3.<\/p>\n<\/td>\n<\/tr>\n

\n

2<\/p>\n<\/td>\n

\n VERIFY ALL SYSTEM DTCs AGAIN<\/b><\/p>\n\n

Yes<\/p>\n<\/td>\n

\n

Replace the instrument cluster, then go to the next step.<\/p>\n

(See INSTRUMENT CLUSTER REMOVAL\/INSTALLATION<\/a>.)<\/p>\n<\/td>\n<\/tr>\n

\n

No<\/p>\n<\/td>\n

\n

Go to the next step.<\/p>\n<\/td>\n<\/tr>\n

\n

3<\/p>\n<\/td>\n

\n VERIFY THAT REPAIRS HAVE BEEN COMPLETED<\/b><\/p>\n\n

Yes<\/p>\n<\/td>\n

\n

Replace the connectivity master unit (CMU), then go to the next step.<\/p>\n

(See CONNECTIVITY MASTER UNIT (CMU) REMOVAL\/INSTALLATION<\/a>.)<\/p>\n<\/td>\n<\/tr>\n

\n

No<\/p>\n<\/td>\n

\n

Go to the next step.<\/p>\n<\/td>\n<\/tr>\n

\n

4<\/p>\n<\/td>\n

\n VERIFY IF OTHER DTCs DISPLAYED<\/b><\/p>\n
    \n
  • \n

    Are any other DTCs displayed?<\/p>\n<\/li>\n<\/ul>\n<\/td>\n

\n

Yes<\/p>\n<\/td>\n

\n

Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.<\/p>\n
