expected reaction after event did not occur
. 
Eliminated due to redundancy with other existing fault 
types. 
58 
1000 
incorrect reaction after event 
This sub type is used for failures where the ECU does 
not see the expected change to a parameter or group of 
parameters in response to a particular event. 
59

circuit/component 
protection 
time-out 
This sub type is used for failures where the ECU detects 
a function is active for greater than a specified time 
period. 
5A 
1010 
plausibility failure 
This sub type is used for failures where the ECU 
compares two or more input parameters for plausibility.

0001 
actuator stuck 
This sub type is used for failures where the ECU does 
not detect any motion in response to energizing a motor, 
solenoid, relay, etc. 
62 
0010 
actuator stuck open 
This sub type is used for failures where the ECU does 
not detect any motion upon commanding the operation 
of a motor, solenoid, relay, etc., to close some piece of 
equipment. 
63 
0011 
actuator stuck closed 
This sub type is used for failures where the ECU does 
not detect any motion upon commanding the operation 
of a motor, solenoid, relay, etc., to open some piece of 
equipment. 
64 
0100 
actuator slipping 
This sub type is used for failures where the ECU detects 
excessive duration to command a motor, solenoid, relay, 
etc., to move a piece of equipment to a desired position. 
65 
0101 
emergency position not 
reachable 
This sub type is used for failures where the ECU is 
unable to command a motor, solenoid, relay, etc., to 
move a piece of equipment to the emergency position. 
66 
0110 
wrong mounting position 
This sub type is used for failures where the server 
detects 
incorrectly 
mounted 
components, 
e.g., 
acceleration sensor showing a position error of 90°. 
67 
0111 
incorrect assembly 
This sub type is used for failures where the ECU detects 
that the component has been incorrectly installed (e.g., 
circuits cross-wired) or polarity errors.
