For a complete wiring diagram Refer to Section 8W.When Monitored:Continuously.Set Condition:When the Totally Integrated Power Module (TIPM) detects a OVERCURRENT condition.Possible Causes(L54) RIGHT STOP LAMP CONTROL CIRCUIT SHORT TO GROUND(L54) RIGHT STOP LAMP CONTROL CIRCUIT SHORTED TO VOLTAGETOTALLY INTEGRATED POWER MODULE1. TEST FOR INTERMITTENT CONDITIONTurn the ignition on.With the scan tool, clear all DTC'sTurn the Left Turn Signal on.With the scan tool, read DTC's.Does the scan tool display active: B17B9–RIGHT STOP LAMP CONTROL CIRCUIT OVERCURRENT?YesGo To 2NoThe condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE) 2.
