40-60 seconds of the vehicle starting the DBFB will test the two internal contacts on and off. A successful routine will generate 4 cyclic
audible clicks from the DBFB, as the contactors charge and discharge. If 4 audible clicks are not heard then, using SDD, read the DTC’s
logged and refer to the DTC table shown in step 10 and attached as a PDF file to this SSM.
If the battery has been disconnected go to step 7, else go to step 8
7. If battery has been disconnected reset Battery Monitor – Incorrect battery monitor state will cause the alternator to enter a cyclic
continuous charge mode and ECO Stop will not function. Throttle Adaptions will also need to be reset.
8. Conduct a drive cycle to ensure Eco Stop is functioning. Ensure that the seatbelt is on, electrical load on the vehicle is kept to a
minimum and the outside temperature is >5C(41F)
9. If ECO Stop is correctly activated during the drive cycle return the vehicle to the customer, advising of the parameters that can inhibit
the operation of ECO Stop.
10. If ECO Stop does not activate after the drive cycle and a DTC is generated please refer to the information in the DTC table attached,
after ensuring that all wiring and earth points leading into the Dual Battery Module, Dual Battery Fusebox, Secondary Battery and
Gateway module connector are correctly seated and the circuits are complete.
NOTE: In order for Eco Stop to be active a number of criteria need to be fulfilled such as:
Temperature > 5c (41F)
Battery Charge State > 70%
Seatbelt On
Door Closed
Speed before stop >5mph
Sufficient pressure applied to brake pedal during stop
Vehicle electrical loading
