Checking the power supply and ground for the control module
Check steering wheel module connector A. Check for contact resistance and oxidation.
Check fuse 22 in the passenger compartment fusebox for the steering wheel module.
NOTE:
If the fuse was blown, check the circuit after the fuse. Check for contact resistance and oxidation.
Check the cable for power supply between fuse 22 in the passenger compartment fusebox and the control module terminals #A1 and #A6. Check for an open-circuit.
Check the ground lead between control module #A22 and ground terminal 31/84. Check for an open-circuit.
Check ground terminal 31/84. Check for contact resistance and oxidation.
