4X4 Mode Switch C225
GEM C223
Measure the resistance between mode switch C225-3, circuit 465 (W/LB), and GEM C223-8, circuit 465 (W/LB).
Is the resistance less than 5 ohms?
Yes
GO to A12.
No
REPAIR circuit 465 (W/LB). CLEAR the DTCs. TEST the system for normal operation.
A12 CHECK CIRCUIT 465 (W/LB) FOR SHORT TO POWER
Measure the voltage between mode switch C225-3, circuit 465 (W/LB), and ground.
Is any voltage indicated?
Yes
REPAIR circuit 465 (W/LB). CLEAR the DTCs. TEST the system for normal operation.
No
GO to A13.
A13 CHECK CIRCUIT 465 (W/LB) FOR SHORT TO GROUND
Measure the resistance between mode switch C225-3, circuit 465 (W/LB), and ground.
Is the resistance greater than 10,000 ohms?
Yes
GO to A14.
No
REPAIR circuit 465 (W/LB). CLEAR the DTCs. TEST the system for normal operation.
A14 CHECK CIRCUIT 359 (GY/R) FOR OPEN
