FLASH: Oil Change Monitor Alerts Prematurely
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM).
2008 (JK) Wrangler
NOTE: This bulletin applies to models equipped with a 3.8L engine (Sales Code EGT) built prior to February 22, 2008 (MDH 0222XX).
The customer may experience a premature alert of the Oil Change Monitor. This alert is displayed as â€œCHANgE OILâ€? on the instrument cluster odometer. This condition may be intermittent or may occur after a battery disconnect has occurred. The customer may be
more aware of this condition if the Oil Change Monitor alerts shortly following an oil change.
Do not confuse this condition for an Oil Change Monitor alert due to the Oil Change Monitor not being reset following an oil change.
