In the battery box, set the battery cut-off switch to the OFF position prior to working on the vehicle. Lockout & Tag out (LOTO) must be performed during set-up, maintenance or repair activities. Refer to your local procedure for detailed information regarding the control of hazardous energy. 1. Turn OFF the vehicle • Turn OFF the vehicle electrical system, by turning the ignition switch to the OFF position. SAFETY RECALL SR23-82 Writer: rbv Date Expiration Group No. Page 02.2023 NA 3 3(6) 2. Open the body electrical center compartment. • Open the vehicle electrical center compartment located at the left side of the entrance door steps. 3. Remove the GPS component digital signal connection. • The bad digital signal connection of the GPS is located between VECU (A17) and the throttle position sensor (B25), therefore; look for spliced GPS wires near the IB9 connector of the power distribution center in the vehicle electrical center compartment. NOTE The digital signal of the GPS can be spliced to the wires located at PIN9, 10 or 11 of the IB9 connector as seen below. • Once the GPS digital signal is located, remove it from the IB9 connector corresponding wire. This wire of the IB9 connector must be repaired to ensure proper “interference free” signal so the throttle response is back to normal operation. This will also resolve the VECU communication problem with the CAN network. • Repair the wire using supplied butt splice connector and shrink tubing (solder the connection). NOTE Do not remove or modify other GPS connections. The problem only exist at the digital signal connection. SAFETY RECALL SR23-82 Writer: rbv Date Expiration Group No. Page 02.2023 NA 3 4(6) REF BA WIRING DIAGRAM 4. Connect the GPS negative signal to the VECU. • The GPS must send a negative LDI signal(-) from the power distribution center located in the vehicle electrical center compartment to the VECU vehicle control module. • To send the correct GPS signal, the GPS signal wire must be connected to PIN12 of the power distribution center BB13 connector (BB13:12). This connection will send the signal to PIN17 of the VECU control module CN3 connector (CN3:17 see wiring diag. BA). NOTE Connect the GPS negative signal wire to the power distribution center using supplied wire and terminals (use shrink tubing and solder the terminals) SAFETY RECALL SR23-82 Writer: rbv Date Expiration Group No. Page 02.2023 NA 3 5(6) 5. Turn ON the vehicle. • Turn ON the vehicle electrical system, by turning the ignition switch to the ON position. 6. VECU control module programming. • Using TechTool, VOCOM and related cables, apply the software conversion kit PN: 24336420 to enable the acceleration limiting function. SAFETY RECALL SR23-82 Writer: rbv Date Expiration Group No. Page 02.2023 NA 3 6(6) 7. Check proper operation. • Check proper operation of the vehicle throttle and the engine starting. 8. Turn OFF the vehicle. • Turn OFF the vehicle electrical system, by turning the ignition switch to the OFF position. 9. Close the body electrical center compartment. • Close the vehicle electrical center compartment located at the left side of the entrance door steps.

How Remedy Component Differs from Recalled Component : The issue concerns an inadequately installed component, and not a defective component. After the remedy, the GPS device will be adequately installed on the vehicle. Identify How/When Recall Condition was Corrected in Production : Considering that the issue involves non-Volvo GPS devices that were only installed on a small number of vehicles per a specific client’s request, the recall condition was corrected in production on 2021-10-25 after the last vehicle equipped with the device was built. Other than the subject population, no additional vehicles were equipped with the GPS device. To avoid similar issues in the future, the process that aims to validate the installation instructions of non-Volvo components has been reviewed by Volvo.
