DESCRIPTION
PTC (Positive Temperature Coefficient) heater (A) is an electric heater using a PTC element as an auxiliary heating
device that supplements deficiency of interior heat source in highly effective diesel engine (U engine).
An electric heater heats up the interior by directly heating the air that passes through the heater.
PTC = positive Temperature Coefficient
The name itself implies that the element has a proportional resistance change sensitive to temperature. PTC heater is
installed at the exit or the backside of heater core.
OPERATION PRINCIPLE
ECM outputs a PTC on signal. Operate PTC from 1st setting to 3rd setting with an interval of 15 seconds.
Heat up the air, which passes through a heater core.
OPERATION CONDITION
Judge the condition by ambient temperature is below 5°C, coolant temperature is below 70°C, and battery voltage is
above 11V and engine RPM is above 700RPM.

INSPECTION
Inspect the PTC operation by confirmation logic as below.
1. Entering method
(1) Set the floor mode, maximum heating
(2) Turn off the blower switch
(3) Press the intake button more than 5 times.
(4) Indicator of entire button is flashed with an interval of 0.5 seconds continuously (Manual).
Graphics of the entire LCD display switch on and off with an interval of 0.5 seconds continuously (Automatic)
(5) Confirm the PTC operation by operating the blower switch
Manual : 1~4 step, Automatic: 1~8step.
(6) Each PTC relay is operated with an interval of 3 seconds.
(7) Execute the PTC operation by confirmation logic for 30 seconds.
2. Cancellation method
(1) Select the A/C button or intake button.
(2) IG "OFF".
(3) Cancel the logic after 30 seconds automatically.
3. If the PTC operation is not operated, substitute with a known-good PTC and check for proper operation.
If the problem is corrected, replace the PTC.
