Scheme 71: DTC B16A0: Taillight (RH) circuit open (Open circuit in rear side marker light (RH), taillight (RH)

TROUBLE JUDGMENT

When an open circuit is detected in the rear side marker light, taillight or position light circuit, the ETACS-ECU sets DTC B16A0. If a short circuit is detected, DTC B16A7 is set.

TECHNICAL DESCRIPTION (COMMENT)

The problem detection of rear side marker light, taillight or position light is made based on the digital feed back signal (input signal to ETACS-ECU) which operates the rear side marker light, taillight or position light. When the ignition switch is "ON", the ETACS-ECU determines the rear side marker light, taillight or position light circuit state from the load placed on the line. After 100 ms has elapsed since the start of the check, the ETACS-ECU performs a sampling with each 10 ms. If an abnormality is detected, it increases the counter by 2, and when no abnormality is detected, it decreases the counter by 1. Once the counter reaches "10", the ETACS-ECU sets the DTC B16A0 if the load is detected on the line, and sets the DTC B16A7 if no load is detected.

Check the wiring harness between rear combination light (LH) connector F-25 (terminal 3) and ETACS-ECU connector C-311 (terminal 10). Check the wiring harness between rear combination light (RH) connector F-06 (terminal 3) and ETACS-ECU connector C-311 (terminal 13). NOTE: Also check joint connector C-43 and intermediate connector D-11 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If joint connector C-43 or intermediate connector D-11 is damaged, repair or replace the connector as described in «HARNESS CONNECTOR INSPECTION»(/mitsubishi/lancer-evolution/x-2007-2016/remont/body-electrical/#general-electrical-lancer-evolution) . Q: Is the wiring harness between rear combination light connector and ETACS-ECU connector in good condition? YES: Go to Step 6. NO: The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary.
  6. STEP 6. Retest the system. Check that the taillight illuminates normally. Q: Does the taillight work normally? YES: The trouble can be an intermittent malfunction (Refer to «HOW TO COPE WITH INTERMITTENT MALFUNCTION»(/mitsubishi/lancer-evolution/x-2007-2016/remont/hoistjack/#general-information-lancer-evolution__how-to-cope-with-intermittent-malfunctions) ). NO: Replace the defective rear combination light unit.
