  1. STEP 1. Check the battery. Refer to «BATTERY - EXCEPT EVOLUTION & SPORTBACK»(/mitsubishi/lancer-evolution/viii-2003-2005/remont/charging-system/#battery-except-evolution-sportback) . Q: Is the battery damaged? YES: Charge or replace the battery and then go to Step 4 . NO: Go to Step 2.
  2. STEP 2. Check the charging system. Refer to «GENERATORS & REGULATORS - EXCEPT EVOLUTION & SPORTBACK»(/mitsubishi/lancer-evolution/viii-2003-2005/remont/charging-system/#generators-regulators-except-evolution-sportback) . Q: Is the charging system damaged? YES: Repair the Charging System and then go to Step 4 . NO: Go to Step 3.
  3. STEP 3. Check the harness wires between junction block connector C-211 terminal 2 and ABS-ECU connector B-118 terminal 20. NOTE: After inspecting intermediate connector C-210 and C-122, inspect the wire. If intermediate connector C-210 and C-122 is damaged, repair or replace it. Refer to «HARNESS CONNECTOR INSPECTION»(/mitsubishi/lancer-evolution/viii-2003-2005/remont/oem-general-information/#general-electrical-except-evolution-sportback) . If the connector has been repaired or replaced, go to Step 4. Q: Is the harness wire between junction block connector C-211 terminal 2 and ABS-ECU connector B-118 terminal 20 damaged? YES: Repair it and go to Step 4. NO: Repair the hydraulic unit (integrated with ABS-ECU) and then go to Step 4.
  4. STEP 4 Recheck for diagnostic trouble code. Q: Does DTC 16 reset? YES: Start over at Step 1 . NO: The procedure is complete.
