CURRENT SENSOR INSPECTION [MZR 2.0 DISI i-stop]

id0140j1805300

Current Sensor No.1

1.  Inspect the battery. (See BATTERY INSPECTION [MZR 2.0 DISI i-stop].)

•  If there is a malfunction in the battery, recharge or replace the battery, then go to the next step.

•  If the battery is normal, go to the next step.

2.  Connect the M-MDS to the DLC-2.

3.  Switch the ignition to ON.

4.  Verify that the more the electrical load is increased, the lower the current sensor No.1 output voltage (PID: ALT_CUR_S). (See PCM INSPECTION [MZR 2.0 DISI i-stop].)

•  If it can be verified, go to the next step.

•  If it cannot be verified, replace current sensor No.1. (See CURRENT SENSOR REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)

5.  Verify that the current sensor No.1 output voltage (PID: ALT_CUR_S) with no load is within the specification. (See PCM INSPECTION [MZR 2.0 DISI i-stop].)

•  If not within the specification, replace the current sensor No.1. (See CURRENT SENSOR REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)

Current Sensor No.2

1.  Inspect the battery. (See BATTERY INSPECTION [MZR 2.0 DISI i-stop].)

•  If there is a malfunction in the battery, recharge or replace the battery, then go to the next step.

•  If the battery is normal, go to the next step.

2.  Turn off all electrical loads.

3.  Inspect the current sensor No.1. (See Current Sensor No.1.)

•  If there is a malfunction in current sensor No.1, replace current sensor No.1.

•  If current sensor No.1 is normal, record the detection current value of the current sensor No.1 (PID: BATT_CUR) with no load.

4.  Turn on the headlights (LO) and record the detection current value of the current sensor No.1 (PID: BATT_CUR).

5.  Calculate the power consumption (subtract the value recorded in Step 4 from the value recorded in Step 3).

6.  Disconnect the negative battery cable from the main and sub batteries.

7.  Connect the negative battery cable of the sub battery to the main battery.

8.  Switch the ignition to ON.

9.  Verify that the more the electrical load is increased, the lower the current sensor No.2 output voltage (PID: BATT_B_CUR, unit V). (See PCM INSPECTION [MZR 2.0 DISI i-stop].)

•  If it can be verified, go to the next step.

•  If it cannot be verified, replace current sensor No.2. (See CURRENT SENSOR REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)

10.  Verify that the current sensor No.2 (PID: BATT_B_CUR, unit A) with no load is within the specification. (See PCM INSPECTION [MZR 2.0 DISI i-stop].)

•  If not within the specification, replace the current sensor No.2. (See CURRENT SENSOR REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)

•  If within the specification, record the detection current value of the current sensor No.2 (PID: BATT_B_CUR, unit A) with no load.

11.  Turn on the headlights (LO) and record the detection current value of the current sensor No.2 (PID: BATT_B_CUR, unit A).

12.  Calculate the power consumption (subtract the value recorded in Step 11 from the value recorded in Step 10).

13.  Verify that the difference between the power consumptions calculated in Steps 5 and 12 is within 3A.

•  If the difference between the power consumptions exceeds 3A, replace the current sensor No.2. (See CURRENT SENSOR REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)

14.  Display the DTC using the M-MDS.(See ON-BOARD DIAGNOSTIC TEST [MZR 2.0 DISI i-stop].)

•  If any DTC is displayed, clear it.
