1	Check wiring between front right vehicle level sensor and level control module for short circuit to B+:	Switch off ignition. Pull plugs A and B off level control module. Pull off plug on front right vehicle level control sensor. Switch on ignition. Measure voltage between level control module plug A 'pins 65, 76' and ground and plug B 'pin 83' and ground.	< 0.3 V Go to Step 2	Repair or replace wiring harness. → End
2	Check wiring between front right vehicle level sensor and level control module for short circuit to ground:	Switch off ignition. Measure resistance between level control module plug A 'pins 65, 76' and ground and plug B 'pin 83' and ground.	∞ ° Go to Step 3	Repair or replace wiring harness. → End
3	Check wiring between front right vehicle level sensor and level control module for open circuit:	Measure resistance between level control module plug A 'pins 65, 76' and front right vehicle level control sensor plug 'pins 5, 1' and plug B 'pin 83' and front right level control sensor plug 'pin 6'.	< 5 Ω Go to Step 4	Repair or replace wiring harness. → End
4	Re-calibrate level control module Calibrating level control module, refer to 43 K2 CALIBRATION - AS OF MY 2003 (ALL MODELS EXCEPT CAYENNE S TIO TITAN) .		→ End	Go to Step 5
5	Replace front right vehicle level sensor.		→ End	Go to Step 6
6	Replace level control module.		→ End
