C2304; AIR SPRING SUPPLY CIRCUIT FAULT

G256924t67: CHECK THE LEFT-HAND FRONT AIR SPRING SUPPLY CIRCUIT FOR SHORT TO GROUND
1. Disconnect the left-hand front air spring electrical connector, EC47.
2. Measure the resistance between EC47, pin 01 (WR) and GROUND.
^ Is the resistance less than 10,000 ohms?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G256924t68: CHECK THE LEFT-HAND FRONT AIR SPRING SUPPLY CIRCUIT FOR SHORT TO B+
1. Measure the voltage between EC47, pin 01 (WR) and GROUND.
^ Is the voltage greater than 3 volt?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G256924t69: CHECK THE RIGHT-HAND FRONT AIR SPRING SUPPLY CIRCUIT FOR SHORT TO GROUND
1. Disconnect the right-hand front air spring electrical connector, EC12.
2. Measure the resistance between EC12, pin 01 (WU) and GROUND.
^ Is the resistance less than 10,000 ohms?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G256924t70: CHECK THE RIGHT-HAND FRONT AIR SPRING SUPPLY CIRCUIT FOR SHORT TO B+
1. Measure the voltage between EC12, pin 01 (WU) and GROUND.
