battery anode (stepping motor dormant) is very low (close to 30ohms).
2) Q LINE SENSOR KO
CAN Bus code = 242
- Cause:
When the average voltage of step motor( join CNA#8) is not zero
cuase sfault: Stepping motor voltage is a sine wave of total null voltage.
- Handle:
Check the step motor connection,especially resistance measurement
between CNA# 9 and battery anode (stepping motor dormant) is very low
(close to 30ohms).
3) S.P OUT OF RANGE
CAN Bus code =248
-
Cause: Adjust wrong potentiometer occurs fault. (CPOC1 on CNA#9, CPOC2 on
CNA#8). When choosing single unit output potentiometer, if the output signal goes
beyond between 0.8 V and 4.2 V will be a fault. When choosing double potentiometer,
two ways of output voltage beyond the scope of the 4.5 V to 5.5 V will be a fault
。
- Handle:
Check the wiring of potentiometer, when the connection point
potentiometer damaged can be caust fault alarm.
4) F.B OUT OF RANGE
CAN Bus code =249
- Cause:
Potentiometer feedback (CPOTon CNB#6) signal is wrong
If CPOT out of the range between 0.3Vand 4.7V,alarming
。
- Handle:
Check the wiring of feedback potentiometer. Feedback potentiometer
wiring damage will alarm.
5) POSITION ERROR
CAN Bus code =228
- Cause:
the fault occurred when tests potentiometer feedback
。
1) When the feedback potentiometer is used together with the feedback
encoder, When feedback potentiometer and feedback encoder used
together, and controls steering Angle of steering wheel .
The same setting in the test menu of FEEDBACK ENC and FEEDBACK POT
When both numerical different, more than 20 degrees will be alarm.
(SET MAX FB POT–SET MIN FB POT amount to 180 degree).
2) When encoder feedback and trigger switches used together, if the area
(trigger switch to install and configure area) is not match with encoder
calculation will be alarm.
This area is read through the test menu of FEEDBACK SECTOR
：
Encoder calculated value is read through WHEEL ANGLE of testing
menu. Special note: the actual application is two trigger switch

Treatment: check the potentiometer connection is correct or not . the trigger switch connection between
the CNA# 2 and CNA# 3,check if the inspection wiring is correct or not , and will AUX FUNCTION 11 is set
