NOTE: See attached engine serial number (ESN) list for affected units.
There are two ground wires in the diesel exhaust fluid (DEF) Supply module wiring harness. A
green wire (GRN 3231) is the ground wire for the DEF pressure sensor ground return. A white
wire (WHI 3232) is the ground wire for the DEF supply module tank heater ground return. The
ground wires are installed in the wrong connector cavities on some CM2350 PX7, PX9, ISX12
and ISX15 engines. When the ground wires are installed incorrectly and the DEF supply
module heater turns on, Fault Codes 1981,1921,1922, 1981, 3375, and 3376 can occur.

The illustration below depicts the wires in the wrong locations. The green wire (GRN 3231)
should be located in the number 4 connector cavity. The white wire (WHI 3232) should be
located in the number 6 connector cavity.
Resolution
Contact an original equipment manufacturer (OEM) PACCAR™ dealer for repair instructions.
Please reference Kenworth™ Document 43-035 or Peterbilt™ Document FRN 1213-1.
Relocate the wires in the connector. The green wire should be inserted in cavity number 4. The
white wire should be inserted in cavity number 6.
Follow these steps:
1. Examine the engine control module (ECM) for Fault Codes 1921, 1922, 1981, 3375, and
3376. If these fault codes are active, move to Step 2.
2. Determine the truck build date. If the truck was built in September, October, November,
or December of 2013, proceed to Step 3. If not, follow the published troubleshooting
trees. (This step may fluctuate; PACCAR™ is attempting to understand the dates for
affected units).
3. Determine the DEF tank harness part number. If the part number is P92-8255 Rev C,
proceed to Step 4. If not, follow the published troubleshooting trees.

4. Disconnect the DEF tank harness from the DEF supply module. PACCAR™
nomenclature for this harness is the DEF tank harness. Examine connector pins 4 and 6.
Pin 4 should be a green wire and Pin 6 should be a white wire. If the pins are incorrect,
swap the pins at the DEF supply module connector. Connector P931 (below) shows the
correct pin outs for pins 4 and 6.
