Abs/TCS HU/Cm

WARNING: This page is about a different car, the 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE: ABS/TCS HU/CM is not able to read DTCs nor PIDs for confirming normal communication between instrument cluster. Therefore use scan tool to read PIDs from the instrument cluster in order to confirm normal communication between the two modules.
  1. Access and monitor "PCM_MSG" and "TCM_MSG" of PID using scan tool.
  2. Referring to PID/DATA MONITOR, confirm display status of the PID. See Figure.
