1. VEHICLE BROUGHT TO WORKSHOP
NEXT -- Continue to next step.
2. CUSTOMER PROBLEM ANALYSIS
(a) Interview the customer and confirm the problem.
NEXT -- Continue to next step.
3. CHECK BATTERY
Standard Voltage:
11 to 14 V
HINT
If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.
NEXT -- Continue to next step.
4. CHECK AND CLEAR DTCS*
HINT
*
CAN communication DTCs are stored when there is an open or short in any of the communication wires. Any problems with the
power source of a corresponding ECU or sensor, or problems in the ECU or the sensor itself also cause these DTCs to be stored.
*
If a CAN communication wire connector is disconnected with the power switch on (IG), the ECUs of the corresponding system and
related systems store a DTC.
NEXT -- Continue to next step.
5. CHECK DLC3 BRANCH WIRE AND CAN NO. 1 BUS MAIN WIRE (CANH - CANL)
NOTICE:
*
Turn the power switch off before measuring the resistances between CAN bus main wires and between CAN bus branch wires.
*
Turn the power switch off before inspecting CAN bus wires for a ground short.
*
After the power switch is turned off, check that the key reminder warning system and light reminder warning system are not
operating.
*
Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the power switch, any other
switches or the doors. If any doors need to be opened in order to check connectors, open the doors and leave them open.
HINT
*
Operating the power switch, any other switches or a door triggers related ECU and sensor communication on the CAN. This
communication will cause the resistance value to change.
*
Even after DTCs are cleared, if a DTC is stored again after driving the vehicle for a while, the malfunction may be occurring due
to vibration of the vehicle. In such a case, wiggling the ECUs or wire harness while performing the inspection below may help
determine the cause of the malfunction.
(a) Turn the power switch off.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
