BRAKE CONTROL SYSTEM 5A–51 Chart B-23 Simultaneous Drop-out of Front Speed Sensor Signal (DTC 64 (Flash out) / NOTE: Even after repairing the faulty part the warning Step Action Yes No 1 1. Turn the key off. 2. Disconnect coil integrated module connector. 3. Measure the FL speed sensor resistance between coil integrated module connector (C-4) terminals 2 and 10. Is the resistance between 2.0k and 2.8k ohms? Go to Step 2 Go to Step 3 2 Measure the FR speed sensor resistance between coil integrated Go to Step 5 Go to Step 4 3 Measure the FL speed sensor resistance at the sensor Repair harness abnormality between sensors and coil integrated module. Go to Step 2 Replace sensor. Go to Step 2 4 Measure the FR speed sensor resistance at the sensor Repair harness abnormality between sensors and coil integrated module. Go to Step 5 Replace sensor. Go to Step 5 5 Damage and powered iron sticking to sensor/sensor ring? Repair. Go to Step 6 Go to Step 6 6 Is there play sensor/sensor rotor? Repair. Go to Step 7 Go to Step 7 7 Is sensor output normal? (Chart C-1-1&C-1-2 or TC-1) Check for faults in harness between speed integrated module. Fault found: repair, and perform system self-check. No fault found: replace EHCU. Go to Step 8 Replace sensor. Go to Step 8 8 1. Reconnect all components, ensure all components are properly mounted. 2. Clear diagnostic trouble code. Was this step finished? Repeat “Basic diagnostic flow chart" Go to Step 8 |
