INSPECTION PROCEDURE

NOTICE:
* Inspect the fuses for circuits related to this system before performing the following inspection procedure.
* Turn the ignition switch off before measuring the resistances of the CAN main wire and the CAN branch wire.
* 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 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, which causes resistance variation.

PROCEDURE

1. CHECK FOR OPEN IN CAN BUS WIRE (STEERING SENSOR BRANCH WIRE)

(a) Turn the ignition switch off.

(b) Disconnect the D20 spiral cable sub-assembly (steering sensor) connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

(d) Reconnect the spiral cable sub-assembly (steering sensor) connector.

NG -- REPAIR OR REPLACE CAN BRANCH WIRE OR CONNECTOR (CAN-H, CAN-L)
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (STEERING SENSOR - BATTERY AND BODY GROUND)

(a) Disconnect the D20 spiral cable sub-assembly (steering sensor) connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

(d) Reconnect the spiral cable sub-assembly (steering sensor) connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE SPIRAL CABLE SUB-ASSEMBLY Removal
