Page 2 of 3
Root Cause:
• PACCAR™ chassis do not provide a dedicated power source to the aftertreatment
DEF dosing unit. Units equipped with battery disconnect switches can interrupt the
DEF system power down and purge sequence, logging Fault Code 5867.
Verification
• If unit is equipped with a battery disconnect switch; clear fault codes, turn key to
OFF position for two minutes, turn key to ON position and see if Fault Code 5867
returns. If Fault Code 5867 does not return after being cleared, see Resolution
section below.
Resolution
• Verify notification sticker directing proper power down procedures is affixed to
chassis near battery disconnect switch. Contact local PACCAR™ support location
for battery disconnect power notification sticker See Figure 1 below.
• Inform operator of proper power down procedure which requires two minutes before
disconnecting power using battery disconnect switch.
