U3006 - 17:- Control Module Input Power “A” – Circuit Voltage above Threshold
Overview:
-
This fault will come if Input Power "A" is more than threshold voltage (In ignition on & engine running condition)
Input Power "A" - is the Voltage Supply from battery.
ISO Code
U3006 - 17
Customer Symptom
IC (display, gauges etc) goes OFF
Fault Effects (On Vehicle)
Cluster will be OFF
Lamp Status (If Any)
NA
Fault Detection Condition
If Battery(supply) voltage goes above 16V
Normal Operating Condition
IPC shall work normally in the operating voltage range of:
8V to 16V (Tolerance ± 0.2V).
Probable Trouble Area
Discharged Battery
Fuse blown (3 amp)
Battery cable terminal (corroded/Sulphation/Loose)
High resistance within the supply cable.
IPC power connector loose etc.
Healing Condition
N/A
Component Details:-
N/A
Preliminary Checks:-
1. Voltage at the battery terminals should be greater than 8V at the Ignition ON Condition.
2. IPC power supply connector should have greater than 8V for normal functionality of IPC.
3. Check battery cable and IPC connector terminals for damage.
4. Check IPC ECU for pin bend/damage.
