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. https://quickserve.cummins.com/qs3/pubsys2/xml/en/tsb/2017/tsb170085.html 2/4 3/25/2021 Fault Code 5867: PACCAR™ Chassis with Battery Disconnect Switch Figure 1, Battery Disconnect Direction Sticker.
