DTC |
C146E |
Open in ABS Solenoid Relay Circuit |
DESCRIPTION
The ABS solenoid relay is built into the skid control ECU in the brake actuator assembly. The ABS solenoid relay supplies power to the ABS and TRAC solenoids. The skid control ECU (brake actuator assembly) detects an ABS solenoid relay malfunction by performing a self check and relay operation check.

- Inspect the fuses for circuits related to this system before performing the following procedure.
HINT:
When C1241 and/or C1417 is output together with C146E, inspect and repair the trouble areas indicated by C1241 and/or C1417 first.

PROCEDURE
|
1. |
CHECK HARNESS AND CONNECTOR (+BS TERMINAL) |
|
(a) Make sure that there is no looseness at the locking part and the connecting part of the connector. OK: The connector is securely connected. |
|
(b) Disconnect the A33 skid control ECU (brake actuator assembly) connector.
(c) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(d) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
A33-25 (+BS) - Body ground |
Always |
11 to 14 V |
| NG |
|
REPAIR OR REPLACE HARNESS OR CONNECTOR (+BS CIRCUIT) |
|
|
2. |
CHECK HARNESS AND CONNECTOR (GND1 TERMINAL) |
|
(a) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
| NG |
|
REPAIR OR REPLACE HARNESS OR CONNECTOR (GND1 CIRCUIT) |
|
|
3. |
RECONFIRM DTC |
HINT:
- This DTC is stored when a problem is identified in the skid control ECU (brake actuator assembly).
-
The solenoid circuits are located in the skid control ECU (brake actuator assembly).
Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed. Be sure to check if the DTC is output again before replacing the skid control ECU (brake actuator assembly).
(a) Reconnect the A33 skid control ECU (brake actuator assembly) connector.
(b) Clear the DTCs.
Chassis > ABS/VSC/TRAC > Clear DTCs
(c) Turn the ignition switch off.
(d) Start the engine.
(e) Drive the vehicle at a speed of 20 km/h (12 mph) or more for 30 seconds or more.
(f) Check if the same DTC is output.

C146E is not output |

C146E is output |

HINT:
- The skid control ECU (brake actuator assembly) performs self diagnosis of the solenoid circuit after the ignition switch is turned to ON.
- If the normal system code is output (no DTCs are output), slightly jiggle the connectors, wire harnesses, and fuses of the skid control ECU (brake actuator assembly).
- If any DTCs are output while jiggling a connector or wire harness of the skid control ECU (brake actuator assembly), inspect and repair the connector or wire harness.
- If no DTCs were output when reconfirming DTCs, checking for intermittent problems is necessary because it is suspected that the original DTCs were stored due to the poor connection of a connector terminal.
