BRAKE CONTROL SYSTEM 5A–55 Chart C-1-3 Rear Sensor Output Inspection Procedure Chart TC-1 Sensor Output Inspection Procedure Step Action Yes No 1 1. Turn the key off. 2. Disconnect coil integrated module connector. 3. Jack up the vehicle with all four wheels off the ground measure the AC voltage between coil integrated module Is the check between coil integrated module connector (C-4) Go to Step 2 OK. Go to Step 3 2 1. Disconnect the wheel speed sensor. 2. Measure resistance between the wheel speed sensor connector terminals 1 and 2. Is the check between connector (F-4) terminals 1 and 2 within Connector is faulty, or open or short circuit of harness between wheel speed sensor connector and coil integrated module. Inspect and correct the connector or harness. Go to Step 3 Wheel speed sensor is faulty. Replace the wheel speed sensor. Go to Step 3 3 Reconnect all components, ensure all components are properly Repeat the “Basic diagnostic flow chart" Go to Step 3 Step Action Yes No 1 1. Connect TECH 2. 2. Check the wheel speed of each sensor by Data List. Is the vehicle speed normal? Go to Step 6 Go to Step 2 2 Check the sensor harness for suspected disconnection (check Replace speed sensor. Go to Step 4 Repair. Go to Step 3 3 Check the wheel speed of each sensor by Data List. Go to Step 6 Go to Step 4 4 Check the sensor rotor. Replace speed sensor. Go to Step 5 Replace sensor rotor. Go to Step 5 5 Check the harness between coil integrated module and speed Go to Step 6 Repair harness or connector integrated module and speed sensor. Go to Step 6 6 Reconnect all components, ensure all components are properly Repeat the “Basic diagnostic flow chart" Go to Step 6 |
