IDLE SWITCH INSPECTION [MZR-CD (RF Turbo)]

Note

• Perform the following test only when directed.

1. Verify that the accelerator position sensor is normal.

2. Visually inspect all accelerator pedal components for looseness.

3. Verify that the idle switch is installed to the accelerator pedal properly.

4. Verify that the power circuit voltage.

(1) Verify that the voltage between the PCM terminals 90 (power circuit) and 91(GND circuit) is 4.75-5.25 V.

Note

• Voltage at the PCM terminal 10 may deviate when the power circuit voltage is abnormal.

5. Verify that the voltage at the PCM terminal 31 (idle signal) is 1 V or less with the accelerator pedal fully released.

6. Depress the accelerator pedal gradually and hold the pedal when the PCM terminal 31 voltage changes to approximately 10 V.

7. Verify that the voltage between the PCM terminals 10 (accelerator position detection signal) and 91 is within the specification.

• If the circuit is normal, replace the idle switch.

1.0-1.2 V (Target value: 1.1 V)

Circuit Open/Short Inspection

1. Inspect for open/short circuit in the following wiring harnesses.

• If there is open/short circuit, repair or replace wiring harnesses.

Open circuit

• Signal circuit

- Idle switch terminal A and PCM terminal 31

• GND circuit

- Idle switch terminal B and GND

Short circuit

• Signal circuit

- Idle switch terminal A and PCM terminal 31 to GND
