10
0000 reserved
11
0001 above maximum threshold
This sub type is used for failures where some circuit
quantity is above a specified range.
12
0010 below minimum threshold
This sub type is used for failures where some circuit
quantity is below a specified range.
13
0011 voltage low/high temperature
This sub type is used for failures where a temperature
sensor with a negative temperature coefficient detects a
voltage below a specified range.
14
0100 voltage high/low temperature
This sub type is used for failures where a temperature
sensor with a negative temperature coefficient detects a
voltage above a specified range.
15
0101 signal rising time failure
This sub type is used for failures where the signal rise
time is outside a specified range.
16
0110 signal falling time failure
This sub type is used for failures where the signal fall
time is outside a specified range.

17
0111 signal shape/ waveform failure
This sub type is used for failures where the shape of the
signal (plot of the amplitude with respect to time) is not
correct, e.g., improper circuit impedance.
18
1000 signal amplitude < minimum
This sub type is used for failures where the ECU
measures a signal voltage below a specified range but
not necessarily a short to ground, e.g., gain too low.
19
1001 signal amplitude > maximum
This sub type is used for failures where the ECU
measures a signal voltage above a specified range but
not necessarily a short to battery, e.g., gain too high.
1A
1010 bias level out of range
This sub type is used for failures where the ECU applies
a bias voltage to a circuit upon which is superimposed a
signal voltage, e.g., Oxygen Sensor circuit.
1B
1011 signal cross coupled
This sub type is used for failures where the ECU detects
a circuit shorted to another circuit when both circuits are
controlled by the ECU.
1C
1100 reserved
1D
1101 reserved
1E
1110 reserved
1F
1111 intermittent
This sub type is used for failures where the ECU
momentarily detects one of the conditions defined above
but not long enough to set a specific sub type.
