CHECK HARNESS AND CONNECTOR (+BS TERMINAL)
CHECK HARNESS AND CONNECTOR (GND1, GND2 AND GND3 TERMINAL)
DTC C146E Open in ABS Solenoid Relay Circuit
DTC C146F Short in ABS Solenoid Relay Circuit
DESCRIPTION
The solenoid relay is built into the master cylinder solenoid.
This relay supplies power to each solenoid. If the initial check is OK, after the ignition switch is turned to ON, the relay turns on.
DTC Code | DTC Detection Condition | Trouble Area |
C146E | Either condition is met: Both of the following conditions continue for at least 0.2 seconds. IG voltage is between 9.5 and 17 V. The relay contact is open when the relay is on. Both of the following conditions continue for at least 0.2 seconds. IG voltage is 9.5 V or less when the relay is on. The relay contact remains open. | ABS2 fuse Solenoid relay circuit Master cylinder solenoid |
C146F | The following condition continues for at least 0.2 seconds. The relay contact is closed immediately after turning the ignition switch ON when the relay is off. |
WIRING DIAGRAM
Refer to DTCs C1225, C1226, C1227, C1228, C1468, C1469, C146A and C146B ().
INSPECTION PROCEDURE
- NOTICE:
1.CHECK HARNESS AND CONNECTOR (+BS 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 Condition Specified Condition A24-31 (+BS) - Body ground Always 11 to 14 V

OK | |
2.CHECK HARNESS AND CONNECTOR (GND1, GND2 AND GND3 TERMINAL) |

Turn the ignition switch off.
Disconnect the skid control ECU (master cylinder solenoid) connectors.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition A24-1 (GND1) - Body ground Always Below 1 Ω A24-32 (GND2) - Body ground Always Below 1 Ω A25-4 (GND3) - Body ground Always Below 1 Ω

OK | |
3.RECONFIRM DTC |
- HINT:
- These codes are stored when a problem is detected in the master cylinder solenoid.
- The solenoid relay is in the master cylinder solenoid.
- Therefore, solenoid relay circuit inspections and relay unit inspections cannot be performed. Be sure to check if any DTC is output before replacing the master cylinder solenoid.
Clear the DTCs ().
Turn the ignition switch off.
Drive the vehicle at a speed of approximately 32 km/h (20 mph) or more for 60 seconds or more.
Check if the same DTCs are output ().
- HINT:
- Reinstall the sensors, connectors, etc. and restore the previous vehicle conditions before rechecking for DTCs.
Result | Proceed to |
DTC is not output | A |
DTC is output (for LHD) | B |
DTC is output (for RHD) | C |
