Engine Monitoring Lamps
Oil Level Switch Installation Status
OEM
Description:
The Oil Level Switch Installation Status parameter is
only available on medium duty on-highway engines
when the Truck Manufacturer parameter is programmed
to GM and the Truck Model parameter is programmed to
GMT-560.
This parameter confi gures the ECM to monitor a
normally-opened OEM-installed oil level switch mounted
in the oil pan and wired to the ECM’s engine connector
(J2). Proper oil level keeps this switch closed, but if the
oil level is too low, the switch will be opened. The ECM
reads the status of the switch on each power-up. If
three sequential engine starts show an open switch, low
oil level is indicated.
Available:
3126E, C7, C9 medium duty engines (GMT560 only)
Range:
Range Cat Default

Advantages:
This parameter enables the operator of a GMT-560 truck
with a medium duty engine the ability to more closely
monitor the engine oil level via an OEM-installed oil level
switch.
Disadvantages:
None
