ATM Test

NOTE: Chrysler Diagnostic Readout Box is required to perform ATM test. Follow manufacturer's instructions on use of diagnostic readout box. If diagnostic readout box is not available, multiple test procedures may need to be performed to diagnose vehicle.

ATM test is used to check functionality of fuel injectors, ignition and Automatic Idle Speed (AIS) motor. While performing ATM test, record "Y" if fuel and spark are present, and AIS motor actuates, or "N" if fuel or spark are not present, or AIS motor does not actuate (i.e. YYY, NNN or NNY).
