Speed Sensor
This diagnostic code is associated with speed sensor transmission
(Transmission Output 1)
output No. 1. FMI 02 means ECM has determined signal frequency or
Incorrect, Intermittent, or
pulse width is not within expected range. There are two speed sensors
Erratic Data Signal.
for transmission output. This diagnostic code occurs when one sensor
is recording a speed and other sensor is not. ECM will log diagnostic
code.

Engine ECM
This diagnostic code is recorded when engine ECM is not sending
Abnormal Update.
parameters to machine ECM at proper rates. Update rate for parameters
generated by engine ECM is not correct.
Possible causes of this diagnostic code are:
Data link circuit has an open circuit.
Data link circuit is shorted to battery ground.
Engine ECM is not operating properly.
Software for engine ECM has been erased.
Engine ECM has wrong software.
0600 03
Temperature Sensor
This diagnostic code is recorded when ECM reads hydraulic oil
(Hydraulic Oil)
temperature sensor signal voltage and voltage is too high. Possible
Voltage Above Normal.
causes of this diagnostic code are: sender has failed, sender return
circuit is open in machine harness, signal circuit in machine harness is
shorted to a source of positive voltage, signal circuit in machine harness
is open or sender is disconnected, or ECM has failed (such a failure is
unlikely). ECM will log diagnostic code.
0600 04
Temperature Sensor
This diagnostic code is recorded when ECM reads hydraulic oil
(Hydraulic Oil)
temperature sensor signal voltage and voltage is too low. Possible
Shorted to Ground.
causes of this failure are: sender has failed, signal circuit in machine
harness is shorted to ground, or ECM has failed (such a failure is
unlikely). ECM will log diagnostic code.
0629 04
Switch (Neutralizer)
This diagnostic code is associated with transmission neutralizer
Shorted to Ground.
override switch. Switch is connected to one ECM input. Switch is a
momentary switch, and is only grounded when switch is pressed. This
FMI 04 means ECM has determined contact is closed for a too long
time period.
0668 02
Shift Lever Input
This diagnostic code is recorded when ECM determines signal from
Invalid Signal.
shift lever is invalid.
