PCM And Generator Shearing Inspection
- Connect the M-MDS to the DLC-2.
- Inspect as follows:
GENERATOR DIAGNOSIS CHART
| Step | Inspection | Action | |||
|---|---|---|---|---|---|
| 1 | Measure the generator terminal B voltage when the electrical loads(1) are on and off. | 15 V or more | Go to Step 2. | ||
| 13-15 V | Normal(2) | ||||
| 13 V or less | Go to Step 3. | ||||
| 2 | Monitor the ALTT V PID using the M-MDS, (See
ON-BOARD DIAGNOSTIC TEST [13B-MSP]
.) or measure the PCM 2AJ terminal waveform using an oscilloscope. (See
PCM INSPECTION [13B-MSP]
.) Is the value normal? |
Yes | Go to Step 4. | ||
| No | PCM input error. | ||||
| 3 | Monitor the ALTT V PID using the M-MDS, (See
ON-BOARD DIAGNOSTIC TEST [13B-MSP]
.) or measure the PCM 2AJ terminal waveform using an oscilloscope. (See
PCM INSPECTION [13B-MSP]
.) Is the value normal? |
Yes | Go to Step 5. | ||
| No | PCM input error. | ||||
| 4 | Monitor the ALTF PID using the M-MDS, or calculate the duty value of the PCM terminal 2AI using an oscilloscope. Is the duty value 100%? | Yes | PCM input error. | ||
| No | PCM, generator, or both are not normal. | ||||
| 5 | Monitor the ALTF PID using the M-MDS, or calculate the duty value of the PCM terminal 2AI using an oscilloscope. Is the duty value 0%? | Yes | PCM input error. | ||
| No | PCM, generator, or both are not normal. | ||||
