Message Center Switch Module

  1. Instrument cluster monitors resistance readings of message center switch module to determine which switch is depressed.
  2. Check for response with any switch depressed. If instrument cluster does not respond, check continuity of circuit No. 875 (Black/Light Blue or Pink/Orange wire) and circuit No. 143 (Light Blue/Yellow wire) between instrument cluster and message center switch module. Switch module is located near message center.
  3. If responses are incorrect, check message center switch module resistance with specified button depressed. See MESSAGE CENTER SWITCH MODULE RESISTANCE SPECIFICATIONS  table.
