Pinout Values and Diagnostic Parameters

CHECK AT THE POWER-TRAIN CONTROL MODULE (PCM)

TERMINAL VOLTAGE CHECK CHART
1. Connect a needle-nosed wire probe (paper clip etc.) to a voltmeter probe.
2. Insert the needle-nosed wire probe into each of the PCM connector terminals from the wire side, and measure the voltage while referring to the check chart.

NOTE:
- Measure voltage with the PCM connectors connected.
- You may find it convenient to pull out the PCM to make it easier to reach the connector terminals.
- Checks don't have to be carried out in the order given in the chart.

CAUTION: Short-circuiting the positive(+) probe between a connector terminal and ground could damage the vehicle wiring, the sensor, PCM, or all three.Use care to prevent this.

4. If voltmeter shows any deviation from standard value, check the corresponding sensor, actuator and related electrical wiring, then repair or replace.
5. After repair or replacement, recheck with the voltmeter to confirm that the repair has corrected the problem.

TERMINAL RESISTANCE AND CONTINUITY CHECK
1. Turn the ignition switch to OFF.
2. Disconnect the PCM connector.
3. Measure the resistance and check for continuity between the terminals of the PCM harness-side connector while referring to the check chart.

NOTE:
- When measuring resistance and checking continuity, a harness for checking connect pin pressure should be used instead of inserting a test probe.
- Checks do not have to be carried out in the order given in this chart.

CAUTION: If resistance or continuity checks are performed on the wrong terminals, damage to the vehicle wiring, sensors, PCM, and/or ohmmeter may occur. Use care to prevent this.

3. If the ohmmeter shows any deviation from the normal condition, check the corresponding sensor, actuator and related electrical wiring, and then repair or replace.
4. After repair or replacement, recheck with the ohmmeter to confirm that the repair or replacement has corrected the problem.
