WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
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. |
DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL |
(a) Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the main wire and branch wire.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable
is reconnected (See page ).
|
2. |
CHECK FOR OPEN IN CAN BUS WIRE (STABILIZER CONTROL ECU BRANCH WIRE) |
(a) Disconnect the F70 stabilizer control ECU connector. |
|
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection |
Switch Condition |
Specified Condition |
---|---|---|
F70-29 (CANH) - F70-28 (CANL) |

REPAIR OR REPLACE STABILIZER CONTROL ECU BRANCH WIRE OR CONNECTOR (CANH, CANL) |
|
3. |
CHECK HARNESS AND CONNECTOR (STABILIZER CONTROL ECU - BATTERY AND BODY GROUND) |
(a) Connect the cable to the negative (-) battery terminal. NOTICE: When disconnecting the cable, some systems need to be initialized after
the cable is reconnected (See page |
|
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

DTC CHECK / CLEAR
1. CHECK DTC
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / (desired system) / DTC.
(e) Read the DTCs.
2. CLEAR DTC
(a) Connect ...
Diameter of the Tire is not Uniform (C1337)
DESCRIPTION
The skid control ECU measures the speed of each wheel by receiving signals from
the speed sensors. These signals are used for recognizing that all 4 wheels are
operating properly. Therefore, all wheel signals must indicate the same speed.
