DTC B16A8: Taillight (LH) Circuit Short < Short Circuit In The Position Light (LH) Circuit, Taillight (LH) Circuit Or The License Plate Light Circuit >: Diagnosis
WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
Required Special Tools:
- MB992006: Extra fine probe
- MB991223: Harness set
- STEP 1. Bulb check
Check the bulb(s) of the light that does not illuminate.
Q: Is the check result normal?
- YES: Go to Step 2.
- NO: Replace the bulb(s) of the light that does not illuminate.
- STEP 2. Resistance measurement at the headlight assembly (position/side maker: LH) connector, rear combination light (tail/side maker: LH) connector, license plate light (LH) connector and license plate light (RH) connector (ground terminals).
- Disconnect the connector, and measure at the wiring harness side.
- Measure the resistance between the connector terminal of light which does not illuminate and ground.
- Measure the resistance between the headlight assembly (position/side maker: LH) connector (ground terminal) and ground.
- Measure the resistance between the rear combination light (tail/side maker: LH) connector (ground terminal) and ground.
- Measure the resistance between the license plate light (LH) connector (ground terminal) and ground.
- Measure the resistance between the license plate light (RH) connector (ground terminal) and ground.
OK: The resistance should be 2 ohms or less
Q: Is the check result normal?
- YES: Go to Step 4.
- NO: Go to Step 3.
- STEP 3. Check of open circuit in ground lines between the headlight assembly (position/side maker: LH) connector, rear combination light (tail/side maker: LH) connector, license plate light (LH) connector or license plate light (RH) connector and ground.
Q: Is the check result normal?
- YES: Go to Step 5.
- NO: Repair the connector(s) or wiring harness.
- STEP 4. Check of short to power supply, short to ground, and open circuit in (TAL1, TAL2) lines between the headlight assembly (position/side maker: LH) connector, rear combination light (tail/side maker: LH) connector, license plate light (LH) connector or license plate light (RH) connector and ETACS-ECU connector.
Q: Is the check result normal?
- YES: Go to Step 5.
- NO: Repair the connector(s) or wiring harness.
- STEP 5. Using scan tool (M.U.T.-III), Check whether the diagnostic trouble code is stored again. CAUTION: To prevent damage to scan tool (M.U.T.-III), always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool (M.U.T.-III).
- Connect scan tool (M.U.T.-III). Refer to "HOW TO CONNECT SCAN TOOL (M.U.T.-III) ".
- Erase the DTC.
- Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
- Check if DTC is stored.
Q: Is the DTC stored?
- YES: Replace the ETACS-ECU.
- NO: The diagnosis is complete.
