Check the CONSULT-II's "Charger Input" reading (see Figure 15).
NOTE:
^
"Battery Voltage" is the voltage level of CONSULT-II's battery.
^
"Charger Input" is the voltage level of the vehicle's battery. (It must be above 12 volts.)
NOTE:
The "Charger Input" reading MUST be above 12 volts (see Figure 15).
^
A reading above 12 volts confirms;
a.
The DLC-II is properly connected to the vehicle,
b.
The vehicle battery voltage is sufficient for ECM reprogramming, and
c.
CONSULT-II has a sufficient power supply to perform ECM reprogramming.
^
If the vehicles battery voltage ("Charger Input") is below 12 volts, one or more of the following may be the cause:
a.
The battery charger you hooked up in section 1 is not charging the battery (poor connection or it is not working).
b.
The DLC-II does not have a good connection to the vehicle (not straight).
c.
The DLC-II cable may have a malfunction (damaged wire or pins).
d.
The CONSULT-II Converter (J44200-50 / black box) is not working correctly (see Figure 12).
CAUTION:
^
Do not attempt ECU reprogramming if the vehicle's battery voltage is below 12 volts.
^
Permanent ECU damage can occur if the vehicle battery does not maintain the minimum voltage during ECU reprogramming.
^
If "Charger Input" is above 12 volts, power from the vehicle battery will keep CONSULT-II's power supply at the correct level during
reprogramming. (see Figure 15).
