Turn the theft deterrent system OFF.
6. Sensors
A. The coolant temperature sensor must provide a correct signal in order for cold mode operation to operate correctly.
Refer to "Cold Mode Operation" within the Systems Operation, "General Information".
B. Verify that the coolant temperature on Cat ET is reasonable for the conditions that are present.
Sensor output
Result: The sensor is operating properly.
Proceed to Test Step 7.
Result: The sensor is not operating properly.
Refer to Troubleshooting, "Sensor Signal (Analog, Passive) - Test" for troubleshooting information.
7. Engine Speed/Timing
A. Crank the engine and observe the engine speed on the Cat ET status screen. Refer to Troubleshooting, "Speed/Timing - Test" for additional information.
Upon initial cranking, the status for engine speed may indicate that the engine speed signal is abnormal. This message will be replaced with an engine speed once the ECM is able to calculate a speed from the signal.
Timing signal
Result: The timing sensor is operating properly.
Result: The timing sensor is not operating properly.
Refer to Troubleshooting, "Speed/Timing - Test" for troubleshooting information.
