Control Module
Input Power "A"
- circuit voltage
above threshold
1) Fuses in Fuse box
2) Battery Supply line
3) Alternator overcharging
1) Check wiring Connections &
connectors of power supply if
damaged than Replace the vehicle
wiring harness or connector.
2) Measure supply voltage (> 11.5 V)
at ECU power supply connector from
wiring harness side if voltage is > 16V
than check the battery if required
replace/repair the battery.
3)Check resistance between vehicle
ground and ground at the power
supply connector(should be <1 ohm) if
resistance did not meet the
requirement check the wiring
connection and if problem still persist
than replace the wiring harness.
4) Check the fuses in Fuse box (J-
Case Fuse (60 Amp)) if fuse is blown
than replace a fuse.
5) Check the power supply line for
short circuit if persist change the
wiring harness.
6) Check alternator voltage (13.5 V to
14.5 V in engine running condition) if
output is not correct than repair /
replace the alternator.
