Monitor the ALTT V PID using the M-MDS or equivalent, or measure
the voltage of PCM terminal 2AJ using a tester. Is the voltage between 13
and 15 V?
Yes
Go to Step 4.
No
PCM input error.

the voltage of PCM terminal 2AJ using a tester. Is the voltage between 13
and 15 V?
Yes
Go to Step 5.
No
PCM input error.
Monitor the ALTF PID using the M-MDS or equivalent, or calculate the
duty value of the PCM terminal 2AI using an oscilloscope. Is the duty
Yes
