Troubleshooting Section
The starting aid is used to improve the engine starting
when the engine is cold. With the keyswitch in the ON
position, the engine Electronic Control Module (ECM)
will monitor the coolant temperature and the engine
intake manifold air temperature in order to decide if
the glow plugs are required to be switched ON. If the
glow plugs are required, then the ECM will activate
the starting aid relay for a controlled period of time.
While the glow plug start aid relay is activated, the
glow plug start aid relay will supply power to the glow
plugs.
Electronic Service Tool Test Aid
The electronic service tool includes the test "Glow
Plug Override Test". The "Glow Plug Override Test"
will assist the analysis of the cold starting aid.
Overview of the Glow Plug Override Test
This glow plug override test switches on the cold
starting aid when the engine is not running. The glow
plug override test aids the analysis of the circuit for
the glow plug start aid relay.
