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(L133) HEADLAMP LEVELING MOTOR CONTROL CIRCUIT SHORT TO GROUND(L133) HEADLAMP LEVELING MOTOR CONTROL CIRCUIT SHORTED TO VOLTAGETOTALLY INTEGRATED POWER MODULE1. TEST FOR INTERMITTENT CONDITIONTurn the ignition on.With the scan tool, clear all DTC'sTurn the Headlamps on.With the scan tool, read DTC's.Does the scan tool display active: B17BA-HEADLAMP LEVELING MOTOR 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. (L133) HEADLAMP LEVELING MOTOR CONTROL CIRCUIT SHORT TO GROUNDTurn the ignition off.Disconnect the TIPM C7 harness connector.Disconnect the Headlamp harness connector.Measure the resistance between ground and the (L133) Headlamp Leveling Motor Control circuit.Is the resistance above 10k ohms?YesGo To 3NoRepair the (L133) Headlamp Leveling Motor Control circuit for a short to ground.Perform the BODY VERIFICATION TEST-VER1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE) 3. (L133) HEADLAMP LEVELING MOTOR CONTROL CIRCUIT SHORTED TO VOLTAGETurn the ignition on.Measure for voltage on the (L133) Headlamp Leveling Motor Control circuit.Is there any voltage present?YesRepair the (L133) Headlamp Leveling Motor Control circuit short to voltage.Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE) NoReplace the Totally Integrated Power Module (TIPM) in accordance with the Service Information.Perform the BODY VERIFICATION TEST - VER 1.
