PCM PCA
- This PCA is located inside the PCM and monitors internal PCM
sensors and pulses the control solenoids. The PCA contains the control
algorithm, monitors the primary pressure directly from the selected PMM, and
interfaces with the main PCA.
LED indication (located on the PM600 module PCA - visible when you service
the PM600 module):
•
Application running - on/off blink at 1 second intervals
•
Application running, no communication - on/off blink at 2-second intervals
•
Downloading or no application loaded - pause, double blink
•
Not functioning - full on or full off
Communications / Firmware
Figure 5 shows a high-level summary of the communication inside the Product
chassis. The main PCA and front-panel interface communicate with USB. The
main PCA, solenoid drivers, PMM, and PCM interface communicate over a
canbus interface.
