For a complete wiring diagram Refer to Section 8W.When Monitored:With the ignition on.Set Condition:The TIPM detects a short to ground on either CAN Interior Bus (125K) circuit.Possible Causes(D265) CAN INTERIOR BUS (125K)(+) CIRCUIT SHORTED TO GROUNDANY CAN INTERIOR BUS MODULETOTALLY INTEGRATED POWER MODULE1. TEST FOR INTERMITTENT CONDITIONTurn the ignition on.With the scan tool, record and erase TIPM DTC's.Cycle the ignition from on to off 3 times.Turn the ignition on.With the scan tool, read active TIPM DTC's.Does the scan tool display this DTC as active?YesGo To 2 NoThe conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.2. ANY CAN INTERIOR BUS (125K) MODULE— INTERNAL SHORTWhen performing this step, turn the ignition off (wait one minute) before disconnecting any module. When the module is disconnected turn the ignition on.This step is to determine if the fault is internal within a module.While monitoring the scan tool, disconnect each CAN Interior Bus (125K) module one at a time.Check for this DTC to become active after disconnecting each CAN Interior Bus (125K) module the vehicle is equipped with.If the DTC becomes stored when a particular module is disconnected, that module is causing the DTC to set.With all the CAN Interior Bus modules disconnected does the scan tool display this DTC as active?YesGo To 3NoReplace the module that when disconnected caused this DTC to become stored in accordance with the service information.Perform the BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).3. (D265) CAN INTERIOR BUS (125K)(+) CIRCUIT SHORTED TO GROUND

Turn the ignition off.Measure the resistance between ground and the (D265) CAN Interior Bus (125K)(+) circuit at the TIPM C7 harness connector.Is any resistance present?YesRepair the (D265) CAN Interior Bus (125K)(+) circuit for a short to ground.Perform the BODY VERIFICATION TEST – VER 1.(Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).NoInspect the wiring and connectors for damage or shorted circuits. If ok, replace and program the Totally Integrated Power Module in accordance with the service information.Perform the BODY VERIFICATION TEST – VER 1.(Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).
