V70R L5-2.5L Turbo VIN 52 B5254T4 (2007)
Reinstall the battery's negative cable.
Look and listen for unusual vehicle behaviour. Check, for example, if a relay is hot, if it is this can indicate that current is flowing through it.
Note! Do not carry out work inside a vehicle equipped with mass movement sensors as the alarm may be triggered.
Check that the CAN network has continued in "sleep mode", see instructions. Checking Can-net's rest status See: Checking CAN-Net's Rest Status
If the standby current is OK and the CAN network is still in "sleep mode", reset the vehicle.
Note! Do not forget to unlock the trunk lid or tailgate and doors.
If a fault is detected, fault-trace the relevant system. Otherwise continue fault tracing by successive elimination.
Continue - Fault tracing by successive elimination
-------------------------------------------------
Fault tracing by successive elimination
During fault tracing by successive elimination, try to localise 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, use the wiring diagram and signal tables as assistance. 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 the power consumption has not dropped, reinstall the fuse and repeat the procedure with another
fuse.
Note! The vehicle is woken from "sleep mode" when certain fuses are affected. If this is the case, repeat the preparations for standby
measurement 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.
