Control Module (ECM). Please refer
to the vehicle “Operator's Manual”
and “Engine Aftertreatement Systems”

information.
Wait to Start Lamp

needs to warm the intake air prior to
starting the engine.
The ON-time for the “Wait to Start”
lamp will vary depending on the
ambient air temperature. See “Normal
Starting Procedure” on page 4-4.
For vehicles equipped with an “Engine
Starting-Motor Protection” feature,
another function of the “Wait to Start”
lamp is to flash for two minutes if
the starting motor is engaged for 30
seconds or more.
The “Wait to Start” lamp can look like:
•
The words “Wait to Start” spelled
out
•
A symbol similar to the graphic
illustrated
•
The color of the symbol or
words can vary, based on the
manufacturer of the vehicle, but
will typically be red or amber.
