A1: CHECK THE VOLTAGE SUPPLY TO THE DSC CONTROL MODULE
1. Switch the ignition to the OFF position.
2. Disconnect the DSC control module electrical connector FH51.
3. Measure the voltage between DSC control module electrical connector FH51 pin 16, (R) and GROUND FH51 pin 32, (B).
^ Is the voltage less than 12 volts?
-> Yes
Go to [A2]
-> No
Go to [A3]

A2: CHECK THE VOLTAGE SUPPLY FROM FUSE 14 AT THE FRONT POWER DISTRIBUTION BOX
1. Measure the voltage supply from fuse 14 at the front power distribution box.
^ Is the voltage less than 12 volts?
-> Yes
INSTALL a new fuse. CLEAR DTC. TEST the system for normal operation. If the fuse fails CHECK the front distribution box.
-> No
REPAIR the circuit between the DSC electrical connector FH51 pin 16, (R) and the output side of fuse 14 at the front power distribution box. TEST the system for normal operation.

A3: CHECK THE VOLTAGE SUPPLY TO THE DSC CONTROL MODULE
1. Measure the voltage between FH51 pin 33, (R) and GROUND FH51 pin 32, (13).
^ Is the voltage less than 12 volts?
-> Yes
Go to [A4]
-> No
Go to [A5]

A4: CHECK THE VOLTAGE SUPPLY FROM FUSE 22 AT THE FRONT POWER DISTRIBUTION BOX
1. Measure the voltage supply from fuse 22 at the front power distribution box.
^ Is the voltage less than 12 volts?
-> Yes
INSTALL a new fuse. CLEAR DTC. TEST the system for normal operation. If the fuse fails CHECK the front distribution box.
-> No
REPAIR the circuit between the DSC control module electrical connector FH51 pin 33, (R) and the output side of fuse 22 at the front power distribution box. CLEAR DTC. TEST the system for normal operation.

A5: CHECK THE VOLTAGE SUPPLY TO THE DSC CONTROL MODULE
1. Measure the voltage between FH51 pin 22, (KY) and GROUND FH51 pin 32, (13).
^ Is the voltage less than 12 volts?
-> Yes
Go to [A6]
-> No
Go to [A7]

A6: CHECK THE VOLTAGE SUPPLY FROM FUSE 3 AT THE PRIMARY JUNCTION BOX
1. Measure the voltage supply from fuse 3 at the primary junction box.
^ Is the voltage less than 12 volts?
-> Yes
INSTALL a new fuse. CLEAR DTC. TEST the system for normal operation. If the fuse fails CHECK the front distribution box.
-> No
REPAIR the circuit between the DSC control module electrical connector FH51 pin 33, (R) and the output side of fuse 3 at the primary junction box. CLEAR DTC. TEST the system for normal operation.

A7: CHECK THE GROUND SUPPLY TO THE DSC CONTROL MODULE
1. Measure the resistance between the DSC control module electrical connector FH51 pin 32, (B) and GROUND.
^ Is the resistance less than 0.5 ohms?
-> Yes
Go to [A8]
-> No
REPAIR the circuit between the DSC control module electrical connector FH51 pin 32, (B) and GROUND point FH42. CLEAR DTC. TEST the system for normal operation.

A8: CHECK THE GROUND SUPPLY TO THE DSC CONTROL MODULE
1. Measure the resistance between the DSC control module electrical connector FH51 pin 15, (B) and GROUND.
^ Is the resistance less than 0.5 ohms?
-> Yes
INSTALL a new DSC control module. CLEAR DTC. TEST the system for normal operation.
-> No
REPAIR circuit between the DSC control module electrical connector FH51 pin 15, (B) and GROUND point FH42. CLEAR DTC. TEST the system for normal operation.
