4.6 Alarm Codes, Descriptions, and Suggested Actions
Description
PECM PIC: On-board diagnostic indicat‐
ing that a LWH is not working correctly.
This diagnostic is active only when a
SSR output is configured for PECM self-
control, when the loop-back connector is
present. The diagnostic is not active
when the control is from a temperature
controller. If this happens when the out‐
put is controlled by a temperature con‐
troller, it indicates a defective harness
between the DPM and the PECM. (The
PLUG_DETECT pin (#5) is not grounded
and the output is turned on).
PECM PIC: On-board diagnostic indicat‐
ing that an ABH is not working correctly.
This diagnostic is active only when a
SSR output is configured for PECM self-
control, when the loop-back connector is
present. The diagnostic is not active
when the control is from a temperature
controller. If this happens when the out‐
put is controlled by a temperature con‐
troller, it indicates a defective harness
between the DPM and the PECM. (The
PLUG_DETECT pin (#5) is not grounded
and the output is turned on).
PECM PIC: The air bath heater control
cable is missing in J9 and at least one of
the air-bath heaters is non-disabled. If
the cable is missing, the NO_AIR_ABH_x
flag will also be set on the non-disabled
air-bath heater channels.
PECM PIC: The air-bath heater air-sen‐
sor connector is missing and at least one
of the air bath heaters is non-disabled.
PECM PIC: Neither the SYSCON nor the
HMI level 1 LED panel is connected. It
indicates that there is no purge indicator
connected, the PECM has nowhere to
report the purge information.
PECM PIC: The low wattage relay board
is not connected properly to the PECM
electronics.
General Maintenance and Troubleshooting
Action
If associated with an 'Invalid configura‐
tion alarm' (1659), then check the J con‐
nector on the PECM associated with
the specified LWH.
Otherwise, replace the PECM or the ca‐
ble between the DPM and PECM.
If associated with an 'Invalid configura‐
tion alarm' (1659), then check the J con‐
nector on the PECM associated with
the specificed ABH.
Otherwise, replace the PECM or the ca‐
ble between the DPM and PECM.
If the air bath heater is not used, then
disconnect J91 and J92 on PECM in or‐
der to eliminate the alarm.
Otherwise check J9.
Check J10 on PECM.
Check J1302 and J101 on PECM. Ver‐
ify the cable connected into J1302.
Confirm that the relay board is connec‐
ted properly.
Replace the relay board and/or the
PECM electronics.
