DIAGNOSTIC TROUBLE CODE CHART

CAUTIONOn troubleshooting, if the ignition switch is turned ON while disconnecting connector(s), diagnostic trouble code(s) associated with other system may be set. On completion, confirm all systems for diagnostic trouble code(s). If diagnostic trouble code(s) are set, erase them all.
DTC No.Diagnostic item
B16A6Turn-signal fuse blown

DIAGNOSTIC TROUBLE CODE CHART

TROUBLE JUDGEMENT

When the hazard warning light fuse is blown, the ETACS-ECU sets the DTC B16A6.

TECHNICAL DESCRIPTION (COMMENT)

With the DTC not set, when the blown fuse of hazard warning light is detected three times consecutively, the ETACS-ECU sets the DTC B16A3.

TROUBLESHOOTING HINTS

  1. The wiring harness or connectors may have loose, corroded, or damaged terminals, or terminals pushed back in the connector
  2. Malfunction of the ETACS-ECU

DIAGNOSIS

Required Special Tools

  1. MB991958: Scan Tool (M.U.T.-III Sub Assembly) MB991824: Vehicle Communication Interface (V.C.I.) MB991827: M.U.T.-III USB Cable MB991910: M.U.T.-III Main Harness A (Vehicles with CAN communication system)
  1. STEP 1. Fuse check Check if the turn-signal light fuse is normal. Q: Is the check result normal? YES: Go to Step 2. NO: Replace the turn-signal light fuse.
  2. STEP 2. Using scan tool MB991958, Check whether the diagnostic trouble code is reset. CAUTION: To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958. Connect scan tool MB991958. Refer to " «HOW TO CONNECT SCAN TOOL»(/mitsubishi/lancer-evolution/x-2007-2016/remont/steering-column-switches/#hazard-warning-light-switch-except-lancer-evolution__how-to-connect-the-scan-tool) ." Turn the ignition switch to the "ON" position. Erase the DTC. Turn the ignition switch from "LOCK" (OFF) position to "ON" position. Check if DTC is set. Q: Is the DTC set? YES: Replace the ETACS-ECU. NO: The procedure is complete.

TROUBLE SYMPTOM CHART

Inspection Procedure 1: The hazard warning lights do not illuminate

CAUTIONBefore replacing the ECU, ensure that the power supply circuit, the ground circuit and the communication circuit are normal.

If the hazard warning light does not illuminate, the hazard warning light switch input circuit in center panel unit or the ETACS-ECU may have a problem.

  1. Malfunction of center panel unit
  2. Malfunction of the ETACS-ECU
  3. The wiring harness or connectors may have loose, corroded, or damaged terminals, or terminals pushed back in the connector

DATA LIST ITEM 265 Item No. Item name Normal conditions Item 265 Hazard switch ON Q: Does scan tool MB991958 display the items "Hazard switch" as normal condition? YES: (Normal condition is displayed for item) Go to Step 3. NO: (Normal condition is not displayed for item No. 265.) Troubleshoot the ETACS-ECU. Refer to «INSPECTION PROCEDURE 10: ETACS-ECU DOES NOT RECEIVE ANY SIGNAL FROM THE HAZARD WARNING LIGHT SWITCH»(/mitsubishi/lancer-evolution/x-2007-2016/remont/communication-devices/#electronic-time-and-alarm-control-system-etacs-except-lancer-evolution) .
  3. STEP 3. Retest the system Check that the hazard warning light illuminate normally. Q: Does the taillight work normally? YES: The trouble can be an intermittent malfunction (Refer to «HOW TO COPE WITH INTERMITTENT MALFUNCTIONS»(/mitsubishi/lancer-evolution/x-2007-2016/remont/hoistjack/#general-information-except-lancer-evolution__how-to-cope-with-intermittent-malfunctions) ).
