Как это работает:The Glow Lamp indicates the functioning of the glow relay.
ECU controls the glow plug and reduces the exhaust gas by obtaining quick start up and engine warm up during cold start.
DTC Detecting Condition
1. IG key: ON
2. C018 Monitoring of short circuit: Determine as error if short circuit exists on battery side.
Monitor only when the power stage has been actually activated.
3. C019 Monitoring of open: Short circuit to GND, missing or open circuit of wiring and excessive temperature at power stage.
Как это проверить ("полечить"):1.Monitor Scantool Data
1. Check the functioning of the glow (pre-heating) lamp
Actuator Mode: Select Glow Lamp, run it and check if the lamp is turned on in the engine instrument panel.
a. Normal if the lamp is turned on.
If the glow lamp is turned on, the identified fault may have existed previously or intermittently.
2.Check the Supply Voltage to the Glow (Pre-heating) Lamp
1. Instrument panel connector: Disconnect.
2. Ignition Switch: ON
3. Measure the power supply voltage to the glow lamp using a multimeter
a. Voltage: Battery Voltage
NG
1. Check the connection state of the connector
2. Check the fuses
3. Check for the open or short circuit in power supply circuit
IF no abnormality has been identified in the above checks, inspect the glow lamp.
3.Check the Control Signal Circuit for the Glow (Pre-heating) Lamp
1. Instrument panel connector: Disconnect
2. Ignition switch: OFF
3. Check for the conduction through the circuit between the glow lamp and ECU terminal.
a. Normal if conduction is normal
NG
1. Check the connection state of the connector
2. Check for the open or short circuit within the circuit between the glow lamp and ECU.
3. Check the instrument panel
4.Check the Harness and the Connector
1. Disconnect the instrument panel connector
a. Check the connection state of the connector, back out or damage of the terminal and slack of wire.
2. Disconnect the ECU side connector.
a. Check the connection state of ECU connector, back out or damage of the terminal and slack of wire.
If the fault is intermittent, check the vehicle while gently shaking the relay or the harness.
NG
1. Repair the faulty part, reconnect air conditioner fan relay, delete DTC using scantool and check if DTC appears again.
