INSPECTION PROCEDURE
NOTICE:
- Turn the ignition switch off before measuring the resistances of CAN bus main wires and CAN bus branch wires.
- After the ignition switch is turned off, check that the key reminder warning system and light reminder warning system are not in operation.
- Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the ignition 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 ignition switch, any switches, or any doors triggers related ECU and sensor communication with the CAN. This communication will cause the resistance value to change.
1 CHECK OPEN IN CAN BUS WIRE (STEERING ANGLE SENSOR BRANCH WIRE)
- Turn the ignition switch off.
- Disconnect the steering angle sensor connector.
- Measure the resistance according to the value(s) in the table below.
Standard resistance
2 CHECK WIRE HARNESS (BAT, IG1, ESS)
- Measure the resistance according to the value(s) in the table below.
Standard resistance
- Measure the voltage according to the value(s) in the table below.
