Is there a glow plug control module circuit?
The circuit is common on all diesels with the exception of the component used to time the glow plug operation. Either the vehicle will have a glow plug control module or the PCM will do this. In lieu of a service manual, just call an auto parts store and ask if they sell a control module. If not, then the computer controls the timing.
What is the DTC glow plug a malfunction error code?
Error Code P0380: DTC Glow Plug/Heater Circuit “A” Malfunction. Error Code P0380 is defined as Glow Plug/Heater Circuit “A” Malfunction. Meaning, there’s a problem with the glow plug heater circuit of the vehicle, causing the vehicle to have difficulty in starting and exhausting smoke.
What does the p0380 glow plug code mean?
A typical diesel engine glow plug: Basically, the P0380 code means that the PCM has detected a fault in the glow plug/heater circuit “A”. Note: This DTC is very similar to P0382 which that code refers to circuit “B”. If you have multiple DTC codes, fix them in the order they appear.
What does it mean when glow plug does not come back?
If the codes DO NOT come back, that means the problem is intermittent, and the glow plug heater circuit is still working properly. If the code comes back however, the technicians will then proceed to check the connectors, wire and fuses around the glow plug heater circuit.
What can glow plug control unit be used for?
The glow plug control unit with Application Specific Integrated Circuit (ASIC) receives requests for glow function from the ECU. It is ideal for flow control and monitoring of low-voltage glow plugs. It offers optimised current control, voltage adaptation and simplified diagnostics.

How are glow plugs distributed in a circuit?
The more glow plugs monitored by a control unit, the higher the current the circuit will need. To reduce the current needed, glow plugs are often distributed across two circuits, with two glow plug relays. This is often used in older glow plug systems.
