00114 Check LIV Circuit
• ACTIVATION: A problem has been detected in the LIV coil circuit. If this alarm is activated while the
control system is calling for LIV to be energized, the circuit is detected shorted. If this alarm is activated at
any other time, the circuit is detected open.
• UNIT CONTROL: Engine and Electric Operation: Alarm only.
• RESET CONDITION: Auto Reset when the LIV coil current draw is normal, or alarm may be manually
reset via keypad or by turning the unit off, then back on again.
NOTE
Follow the steps below until a problem is found. Once a repair or correction has been made, the
active alarm should clear itself (refer to reset condition above). Operate the unit through the appro-
priate modes to see if any active alarm occurs. Continue with the steps below as necessary.
Corrective Actions:
1. Check Coil Wiring - Inspect coil and connector pins and terminals. (See wiring schematic Section 10.2.)
Verify there is no physical damage to the coil. Verify there is no damage, moisture or corroded pins in
plug.
2. Check Current Draw
a. Use Component Test mode to test actual current draw of the circuit. (Refer to Section 5.2.4.) View
current draw in Component Test mode screen. Refer to Section 2.11 for normal current values.
b. Check for voltage at the coil plug between pins A (+) and B (ground). Voltage should be
approximately12VDC.
3. Check Coil - Check coil resistance. View current draw in Data List. Refer to Section 2.11 for normal cur-
rent values.
4. Check Circuits With Another Coil - Substitute known good coil and clear alarm. Start unit, run for 30
seconds. If alarm does not reoccur, replace failed coil.
