4. Check continuity between ICC unit harness connector and
ground.
OK or NG
OK >> GO TO 3.
NG >> 1. Repair harness between brake pressure sensor and ICC unit.
2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system
again.
3.CHECK POWER SUPPLY CIRCUIT FOR BRAKE PRESSURE SENSOR
1. Connect ICC unit connector.
2. Turn ignition switch ON.
3. Check voltage between ICC unit harness connector terminals.
OK or NG
OK >> 1. Replace brake pressure sensor. Refer to BR-12,
"Removal and Installation".
2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system
again.
NG >> 1. Replace ICC unit. 2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system
again.
DTC 62 BOOSTER SOL/V CIRCUITINFOID:0000000001328834
1.CHECK SOLENOID/RELEASE SWIT CH AND ICC UNIT CONNECTOR
1. Turn ignition switch OFF.
2. Disconnect brake booster connector and ICC unit connector, and connect them securely again.
3. Erase DTC and perform ICC system running test. T hen perform self-diagnosis of ICC system again.
Is malfunction indicated?
YES >> GO TO 2.
NO >> Poor connector connection 1. Check connector. (Check connector housing for disconnected, loose, bent, and collapsed ter-
minals. If any malfunction is detected, repair applicable part.)
2. Erase DTC and perform ICC system running test. Then perform self-diagnosis of ICC system
again.
