Code No.B16A2 Turn-signal (LH) bulb outage
DIAGNOSTIC FUNCTION
JUDGEMENT CRITERIA
- With the diagnosis code not set, if there is a malfunction
to the left turn-signal lamp bulb, the blown left bulb counter counts once when the illumination
of hazard or turn-signal lamp (left side) is attempted.
- If the blown left bulb counter reaches "3," diagnosis code No. B16A2 is set.
PROBABLE CAUSES
- Malfunction of turn-signal lamp bulb (left side)
- Malfunction of turn-signal lamp assembly (left side) <Integrated in door mirror
type>
- Damaged harness wires and connectors
- Malfunction of the ETACS-ECU
DIAGNOSIS PROCEDURE
STEP 1. Bulb check
Q.
Is the check result normal?
STEP 2. Resistance measurement at the headlamp assembly (TURN: LH) connector, side turn-signal lamp (LH) connector and rear combination lamp (TURN: LH) connector
(1)Disconnect the connector, and measure at the wiring harness side. |
(2)Measure the resistance between the connector terminal of lamp which does not illuminate
and the body earth.

Q.
Is the check result normal?
STEP 3. Check of open circuit in earth line between headlamp assembly (TURN: LH) connector, side turn-signal lamp (LH) connector or rear combination lamp (TURN: LH) connector and the body earth
Q.
Is the check result normal?
STEP 4. Check of open circuit in TL1&TL2-1 line between ETACS-ECU connector and headlamp assembly (TURN: LH) connector
Q.
Is the check result normal?
STEP 5. Check of open circuit in TL1&TL2-1 line between ETACS-ECU connector and side turn-signal lamp (LH) connector <Fender panel attachment type>
Q.
Is the check result normal?
STEP 6. Check of open circuit in TL3-1&TL3-2 line between ETACS-ECU connector and rear combination lamp (TURN: LH) connector
Q.
Is the check result normal?
STEP 7. Check of open circuit in TL2-2 line between ETACS-ECU connector and side turn-signal lamp (LH) connector <Integrated in door mirror type>
Q.
Is the check result normal?
STEP 8. Check whether the diagnosis code is reset.
(1)Erase the diagnosis code. |
(2)Turn the ignition switch from "LOCK" (OFF) position to "ON" position. |
(3)Check if diagnosis code is set. |
