Fault Tracing By Successive Elimination
During fault tracing by successive elimination, try to localize the problem by measuring the power consumption at the same time as removing one fuse at a time in the vehicle.
Procedure
Expose the integrated relay/fusebox in the engine compartment and the fuses in the Central electronic module (CEM).
Use the multimeter and check that the relays and fuses have the correct voltage. Measure between fuses and suitable ground terminals. If any problem is detected, troubleshoot the system in question.
Remove a fuse and read off the standby consumption according to the instructions above. If the power consumption has dropped to less than 25 mA, fault trace the system that the fuse corresponds to. if power consumption has not reduced, repeat the procedure with another fuse.
Remove one fuse at a time and measure. Do not reinstall the fuses until the fault has been found, because it could awaken the car from "sleep mode " and restore the problem. If the vehicle was going to woken from "sleep mode" anyway, repeat the preparations for standby power consumption before continuing successive elimination.
If the fault has not occurred, continue with successive elimination on relays and the connectors for the vehicle's control modules.
