WIRING DIAGRAM
INSPECTION PROCEDURE
NOTICE:
* 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.
* Inspect the fuses for circuits related to this system before performing the following inspection procedure.
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 CAN BUS LINE FOR CONNECTION (ABS AND TRACTION ACTUATOR (SKID CONTROL ECU) BRANCH WIRE)
(a) Turn the ignition switch off.
(b) Disconnect the A30 ABS and traction actuator (skid control ECU) connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

NG -- REPAIR OR REPLACE CAN BRANCH WIRE CONNECTED TO ABS AND TRACTION ACTUATOR (SKID CONTROL ECU) (CAN-H, CAN-L)
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (IG1, GND1, GND2)
(a) Disconnect the A30 ABS and traction actuator (skid control ECU) connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
