For a complete wiring diagram Refer to Section 8W.When Monitored:Continuously.Set Condition:When the Totally Integrated Power Module (TIPM) detects a HIGH condition.Possible CausesCHECK (Z904) GROUND CIRCUIT(Z904) GROUND CIRCUIT OPENCHECK (L89) FRONT LEFT FOG LAMP CONTROL CIRCUIT (L89) FRONT LEFT FOG LAMP CONTROL CIRCUIT OPEN(L89) FRONT LEFT FOG LAMP CONTROL CIRCUIT SHORTED TO VOLTAGEFRONT LEFT FOG LAMP BULBTOTALLY INTEGRATED POWER MODULE1. INTERMITTENT CONDITIONTurn the ignition on.With the scan tool, clear all DTC's.Turn the Front Fog Lamps on.With the scan tool, read DTC's.Does the scan tool display active: B16F9–FRONT LEFT FOG LAMP CONTROL CIRCUIT HIGH?YesGo To 2 NoThe 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. CHECK (Z904) GROUND CIRCUITSDisconnect the Front Left Fog Lamp harness connector.With a 12–volt test light connected to 12–volts, probe each (Z904) Ground circuit.Does the test light illuminate brightly on each ground circuit?YesGo To 4NoGo To 33. (Z904) GROUND CIRCUIT OPENMeasure the resistance of the appropriate (Z904) Ground circuit(s) at the Front Left Fog Lamp harness connector.Is the resistance below 10.0 ohms?YesReplace the Inoperative bulb in accordance with the Service Information.Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE) NoRepair the appropriate (Z904) Ground circuit(s) for an open.Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE) 4. CHECK (L89) FRONT LEFT FOG LAMP CONTROL CIRCUITTurn the ignition on.With a 12–volt test light connected to ground, check the (L89) Front Left Fog Lamp Control circuit.Does the test light illuminate brightly with the fog lamp switch turned on, and shut off with the fog lamps turned off?YesReplace the Inoperative bulb in accordance with the Service Information.Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE) NoGo To 55. (L89) FRONT LEFT FOG LAMP CONTROL CIRCUIT OPENTurn the ignition off.Disconnect the TIPM C4 harness connector.Measure the resistance between the (L89) Front Left Fog Lamp Control circuit and the Front Left Fog Lamp harness connector to the TIPM C4 connector.Is the resistance below 10.0 ohms?YesGo To 6NoRepair the (L89) Front Left Fog Lamp Control circuit for an open.Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE) 6. (L89) FRONT LEFT FOG LAMP CONTROL CIRCUIT SHORTED TO VOLTAGETurn the ignition on.Measure the voltage of the (L89) Front Left Fog Lamp Control circuit.Is there any voltage present?YesRepair the (L89) Front Left Fog Lamp Control circuit for a 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.
