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 (SKID CONTROL ECU BRANCH WIRE) |
(a) Disconnect the A6 master cylinder solenoid (skid control ECU) connector. |
|
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection |
Switch Condition |
Specified Condition |
---|---|---|
A6-11 (CANH) - A6-25 (CANL) |
Ignition switch off |
54 to 69 Ω |

REPAIR OR REPLACE SKID CONTROL ECU BRANCH WIRE OR CONNECTOR (CANH, CANL) |
|
3. |
CHECK HARNESS AND CONNECTOR (SKID 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) Disconnect the A7 master cylinder solenoid (skid control ECU) connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection |

IG2 Signal Malfunction (B2788)
DESCRIPTION
The steering lock ECU determines the on/off status of the engine switch through
the IG2 signal circuit.
The steering lock ECU does not lock the steering when it receives the IG2 relay
on signal. This prevents the steering from being locked wh ...
Auto Up Operation does not Fully Close Power Window (Jam Protection Function
is Activated)
DESCRIPTION
If any door glass or a power window regulator motor does not operate smoothly,
the jam protection function may be triggered automatically, resulting in the auto
up function being unable to fully close the window.
HINT:
This symptom may occur ...
