WIRING DIAGRAM
INSPECTION PROCEDURE
- After replacing the master cylinder solenoid, perform zero point calibration and store the system information ().
| 1.CHECK HARNESS AND CONNECTOR (EXI TERMINAL) |
Turn the ignition switch off.
Disconnect the skid control ECU (master cylinder solenoid) connector.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Switch Condition | Specified Condition |
| A24-27 (EXI) - Body ground | Ignition switch ON | 11 to 14 V |

| 3.CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - 4 WHEEL DRIVE CONTROL ECU/TRANSFER SHIFT ACTUATOR)
|
Disconnect the A24 skid control ECU (master cylinder solenoid) connector.
Disconnect the A27 4 wheel drive control ECU connector.
Disconnect the C37 transfer shift actuator assembly connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| A24-27 (EXI) - A27-14 (P1) | Always | Below 1 Ω |
| A24-27 (EXI) - C37-3 (CDL) | Always | Below 1 Ω |
| A24-27 (EXI) - Body ground | Always | 10 kΩ or higher |
| C37-7 (GND1) - Body ground | Always | Below 1 Ω |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
