54 -CHASSIS ELECTRICAL > 54A-CHASSIS ELECTRICAL > TURN-SIGNAL LAMP > DIAGNOSIS CODE PROCEDURES > CODE NO. B16A5 TURN-SIGNAL LAMP (RH) SHORT CIRCUIT
Code No.B16A5 Turn signal(RH) circuit short
 
 
caution
  • Before replacing the ECU, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
 
 
DIAGNOSTIC FUNCTION
When the right wiring harness of turn-signal lamp is short circuited, the ETACS-ECU sets diagnosis code No. B16A5.
 
 
JUDGEMENT CRITERIA
With the diagnosis code not set, when the short circuit is detected three times consecutively, the ETACS-ECU sets diagnosis code No. B16A5.
 
 
PROBABLE CAUSES
  • Damaged harness wires and connectors
  • Malfunction of the ETACS-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check of short circuit in TR1 line between ETACS-ECU connector and turn-signal lamp (RH) connector
Is the check result normal?
Go to Step 2.
Repair the connector(s) or wiring harness.
 
STEP 2. Check of short circuit in TR2&TR3 line between ETACS-ECU connector and rear combination lamp (TURN: RH) connector
Is the check result normal?
Go to Step 3.
Repair the connector(s) or wiring harness.
 
STEP 3. Check of short circuit in TR2&TR3 line between ETACS-ECU connector and door mirror assembly (RH) connector
Is the check result normal?
Go to Step 4.
Repair the connector(s) or wiring harness.
 
STEP 4. Check whether the diagnosis code is set again.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
(3) Check if diagnosis code is set.
Is the diagnosis code set?
Replace the ETACS-ECU.
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to Cope with Intermittent Malfunction ).
