DESCRIPTION
The ABS solenoid relay supplies power to the ABS solenoid and TRAC solenoid.
The solenoid relay is turned on 1.5 seconds after the ignition switch is turned ON, and is turned off if an open or short in the solenoid is detected by the self diagnosis performed when the engine starts running.
The ABS solenoid relay is housed in the skid control ECU in the actuator assembly.

CAUTION / NOTICE / HINT
NOTICE:
HINT:
When C1241 and/or C1417 is output together with C146E and/or C146F, inspect and repair the trouble areas indicated by C1241 and/or C1417 first.
PROCEDURE
1. |
CHECK TERMINAL VOLTAGE (+BS TERMINAL) |
(a) Turn the ignition switch off.
(b) Make sure that there is no looseness at the locking part and the connecting part of the connectors.
(c) Disconnect the S1 skid control ECU (brake actuator assembly) connector.
(d) Measure the voltage according to the value(s) in the table below. Standard Voltage:
|
|
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:
These codes are detected when a problem is determined in the skid control ECU (brake actuator assembly).
The solenoid circuits are in the skid control ECU (brake actuator assembly).
Therefore, solenoid circuit inspection and solenoid unit inspection cannot be performed.
Be sure to check if any DTCs are output before replacing the skid control ECU (brake actuator assembly).
(a) Reconnect the S1 skid control ECU (brake actuator assembly) connector.
(b) Clear the DTCs (See page ).
(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 recorded (See page ).

Engine does not Start but Initial Combustion Occurs
DESCRIPTION
If the key ID codes of the key and transponder key ECU assembly match, the engine
immobiliser system is unset and the engine start permission signal is sent to the
ECM. When the ID codes of the transponder key ECU assembly and ECM match, the engine
starts.
