Indicator Description
DS19
CAN jack transmitter indicator toggles when a packet is transmitted
• Toggling 10 times per second with DS21 toggling at the same rate – normal
operation
• Toggling slowly (1 second on, 1 second off) with DS21 not toggling – PLR is
transmitting but not receiving, a CAN node is detected but not responding to the
PLR****
• Toggling 10 times per second with DS21 not toggling – PLR is unable to transmit,
no CAN nodes are detected*****
DS20 Fan jack indicator turns on when voltage is active
D21
CAN jack receiver indicator toggles when a packet is received
• Toggling 10 times per second with DS19 toggling at the same rate – normal
operation
• Not toggling with DS19 toggling slowly (1 second on, 1 second off) – PLR is
transmitting but not receiving, a CAN node is detected but not responding to the
PLR****
• Not toggling with DS19 toggling 10 times per second – PLR is unable to transmit,
no CAN nodes are detected*****
DS22 VCAN indicator turns on when voltage is present at the CAN connector
* The receive indicator toggles at the rate that the diagnostic requests are received at
the port. When active, indicators that toggle with received/transmitted diagnostics may
toggle at a
1
/
2
interval, then remain idle for up to 60 seconds.
** This may be an acceptable state if any other ProLink6 receive Indicator 0 on the PLR is
toggling.
*** This may be an acceptable state if any other ProLink6 receive Indicator 1 on the PLR is
toggling.
**** The sensor’s configuration may be wrong, compare the address with the dial on the
sensor and all other sensor configuration parameters.
***** There is a problem with the CAN bus lines. The problem may be the sensor wiring
harness, sensor hardware, or PLR hardware. Check wiring harness connections.
