Toyota CH-R Service Manual: SM Solenoid Circuit (C1225-C1228,C1468,C1469,C146A,C146B)

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 harness, 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.

Open in ABS Motor Relay Circuit (C146C)

DESCRIPTION The ABS motor relay supplies power to the pump motor. While the ABS is activated, the skid control ECU turns the ABS motor relay on to operate the pump motor. If the voltage supplied t ...

Yaw Rate Sensor (C1234,C1472,C1474)

DESCRIPTION The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via CAN communication. HINT: If there is a malfuncti ...
