C.

PASS:

Continue with the below steps 1-3 to perform the
Multi-ECU update:

(NOTE: Refer to TSB 15-GI-001 for the general GDS Mobile ECU update procedures).
1. Perform the GDS ECU updates for each of the 4 systems as shown on the next page.
2. After successful completion of all 4 system updates, perform an All Fault Search for Diagnostic
Trouble Codes and erase any DTC.
3. Confirm normal vehicle operation.
!

WARNING



THE 12V BATTERY VOLTAGE CHECK IS CRITICAL FOR THIS MULTI- ECU UPDATE
AS IT WILL DRAW DOWN THE 12V BATTERY FOR 40 MINUTES AT IGNITION ON.



STOCK VEHICLES ARE PRONE TO LOW BATTTERY CONDITION, SO IT IS BEST TO
OPERATE A STOCK VEHICLE AT READY ON FOR 20 MINUTES PRIOR TO STARTING
THE MULTI-ECU UPDATE.



THIS WILL ENSURE 12V BATTERY WILL BE CHARGED TO AN ADEQUATE LEVEL,
PREVENTING POTENTIAL UPDATE FAILURE OR CONTROLLER DAMAGE.

GDS Vehicle Battery Voltage Warning:
If voltage is below 12 volts as per the below GDS warning, then select Back and operate the
vehicle in Ready mode for at least 20 minutes to ensure an adequate battery state of charge for
reliable update results. Turn ignition back on, and then retry the ECU update again.
