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.
