Glow light bulb could be burned out.but glow plugs is control by ECM AND RELAY.do your vechicle start but you dont see glow plug light on to let you know glow plugs are energized heating up.also check glow plug fuse, look in owner manual in glovecompartment it will show all fuses and relays locations.

Hi,

On your brakelight concern, a few basic ideas:

  • a blown fuse indicates a short somewhere;
  • brakelights are activated by the switch coupled to the brake pedal;
  • the brakelight bulb is integrated with the rear parklights.
Based on the above, some actions that you could take/explore:
  • check the wiring of the foot/pedal switch, might be caught in between the spring coils;
  • check the bulb sockets. look/clean/remove corrosion, rust, twisted wires, frayed ends;
  • check harness going to rear.
On the ticking sound:
  • probably a relay;
  • check for loose ground or corroded/rusted ground points;
  • double check the ground connection of the stereo;
  • double check the battery's - terminal connection to engine and to chassis body;
  • check/clean relay sockets normally located with the main fuses.
  • in some worst case scenario and considering the age of the vehicle, a rehabilitation of the wiring system might be in order.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

changing the module will not remedy the problem unless it is programmed. most likely if the control module had failed the fault stored in the airbag module should be a coding fault. Take the vehicle to your local bmw dealership, pay them to diagnose it and see if it just needs to be programmed. In most areas bmw dealership are opened on saturday usually fairly late

Before you remove them, if your car is starting ok and idling smoothly on all cylinders they will be ok. If you have a misfire for 15 or so seconds, one of your heaters might be duff. If the car is difficult to start and is very rough to begin with, you have two out. (This is assuming your injectors are in good condition because they can give trouble on cold starts also.) The easiest way to find a bad heater is to remove the strap or cable that connects them all and using a multi meter check each one. The one that gives no reading is your problem. If you get your replacement from a spares shop you will pay a fraction of the manufacturers price. (Replace all four if you can afford it. It will save you the bother of having to to the job again in a couple of months and it will give you some spares for an emergency.)

PO380 and p1316 what do thies coads mean.


P0380 - Glow Plug/Heater Circuit "A" Malfunction
Bad glow plug. The glow plug system is used to assist in providing the heat required to begin combustion during cold engine temperatures. The glow plugs are heated before and during cranking, as well as initial engine operation. The engine control module (ECM) controls the glow plug ON times by monitoring coolant temperature and glow plug voltage. The California Glow Plug system has eight individual glow plug supply circuits between the controller and the glow plugs. If the feedback voltage from the controller to the ECM is not within range, DTC P0380 will set.

- The glow plugs are commanded OFF and the glow plug feedback is more than 2 volts. or
- The glow plugs are commanded on and the glow plug feedback is not between 5 volts and 6.2 volts.

Keep in mind that the "wait to start" light only comes on while the voltage is dropping in that circuit. This should only take 3-5 sec's. If it takes longer, refer to your "Likely problem" you listed above. That would be the Heater Module. If your glo plugs stay on, your batteries would be dead in no time. If any of your plugs go bad, they would each be listed on the reader per cyl 1-8. If you need to change the Module,


P1316 - Injector Circuit / IDM Codes Detected.
This code indicates that codes are stored in the IDM

Possible causes are as follows:
- Injector(s) or circuit(s)
- Open or shorted IDM enable circuit
- Open/short in EF circuit
- Open/short in FDCS circuit
- IDM relay
- IDM powering circuits
- Failed IDM
- Failed PCM

Check your Injector Driver Module wires, circuits 821 (Brown/Orange) and 818 (Grey/White) between the PCM and IDM. On the IDM side, the connector pin numbers are 17 for circuit 821, and pin 4 for circuit 818. You should check for high resistance in that circuit, short to ground, or open circuits. If wiring checks out good, you may need to replace your IDM. It's not uncommon for water intrusion into the module, due to its mounting location. Also check the engine wiring harness where it routes up over the driver side shock and/or driver side valve cover. That code is either a key-on/engine-off or a continuous memory code.


Hope this helps (remember to rate this answer).

Glow Plug system diagnosis


I HAD SAME CODE TO BUT NOTE THE CODES MIS READING DUE TO THIS Check under seat unplug control module see if it is wet with fluid . cost me $138.00 fee.
Engine light on than next day off may 2 day then on at same place drive kid to school.
issue with transmission fluid wicking up the harness into the control module and causing the module to malfunction. Usually, the harness from the transmission to the ETC module is replaced and the module is replaced provided the leak is repaired. In some cases this may be more than is actually needed but it usually fixes the concern. Transmission fluid does not actually damage the module and can be flushed away with board cleaning solvent or electrical contact cleaner as a first attempt. Always repair the leak before replacing a module.

Glow plugs causing starting problem


if you need connectors and terminals for the glow plug connections under the valve cover, Ford sells then so you don't need a whole $600 harness.

info for your use

Section 03-07B: Glow Plug System 1996 F-250, F-350, F-Super Duty Equipped with 7.3L Diesel Engines Workshop Manual
DESCRIPTION AND OPERATION Glow Plug System The 7.3L diesel engine uses a glow plug system which preheats air in the combustion chamber to improve cold engine starting. The system consists of eight glow plugs, the glow plug control module (12B533), powertrain control module (PCM) (12A650), engine oil temperature (EOT) sensor and barometric pressure sensor (BARO sensor) (12A644). The glow plug system is electronically controlled by the powertrain control module. The powertrain control module energizes the glow plugs immediately after the key is placed in the ON position and then determines how long the glow plugs will be on according to the engine oil temperature and the barometric pressure. The required time for the glow plugs to be energized decreases as the engine oil temperature and barometric pressure increase. The glow plugs are self-regulating, and the powertrain control module controls relay ON time. The powertrain control module protects the glow plugs by energizing them for short durations if the battery voltage is abnormally high.

Possible Causes: Insufficient glow plug ON time will not allow enough heat to accumulate in the combustion chamber to easily facilitate starting. If the glow plug system ON time does not meet any of the specifications in the accompanying chart the problem is most likely a faulty wire harness connection, ground connections or glow plug relay.

If the glow plug resistance to ground is high, the most likely causes are an open UVC (under valve cover) harness or open glow plug.
--------------------------------------------------------
Relay Operation
Install a DVOM on the glow plug feed side of the glow plug relay (large stud with two wires connected). Turn the ignition key to the ON position but do not attempt to start. Note the time in seconds from when the key is turned on and the glow plug relay energizes until the glow plug relay de-energizes. The glow plug relay makes a loud click noise which is easily heard when it energizes and de-energizes. The dome light will dim and the dash voltmeter will dip when the glow plugs are drawing current from the battery. Compare the times measured to the table (time will be affected by engine temperature, battery condition and vehicle altitude). The voltage at the glow plug feed terminal may vary from 9 to 12 volts depending upon battery condition.
--------------------------------------

-----
If battery voltage not present check for B+ at power supply terminal (terminal with single large wire). Power for glow plug power supply is supplied from starter relay through two fusible links at solenoid.
Glow Plug Operation
Disconnect all of the glow plug/injector harness connectors from the valve cover gaskets. With the pigtail installed, measure glow plug resistance to ground (preferably B-). A resistance measurement of .1 to 6 ohms indicates a good glow plug.



Glow Plug Harness Continuity
Measure for continuity from the connector harness to the glow plug feed terminal on the glow plug relay. Resistance should be less than 5 ohms.
Incorrect measurements will result if all glow plug/injector connectors to valve cover are not disconnected.

---------------------------------------------------
Glow Plug Relay The glow plug relay (12A343) has a plastic base and two mounting bolts. It is operated by the powertrain control module (PCM) (12A650) which senses engine oil temperature, PCM voltage and barometric pressure. When the engine oil temperature or the barometric pressure is low, the PCM activates the glow plug relay and the glow plugs. If the PCM voltage is too high, the powertrain control module deactivates the glow plug relay and the glow plugs immediately energize for a shorter duration, decreasing the modulation of the duty cycle.
-----------------------------------------------
Glow Plug Removal
  1. stj~us~en~file=ani_caut.gif~gen~ref.gif WARNING: THE RED-STRIPED WIRING HARNESS CARRIES 115V DC. SEVERE ELECTRICAL SHOCK MAY BE RECEIVED. DO NOT PIERCE.
    Remove valve cover (6582). Refer to Section 03-01D .
  1. Disconnect glow plug electrical connector using a pair of pliers.
  1. Remove glow plug using 10mm socket.
  1. Clean and inspect glow plug tip for damage. Replace if damaged.
Installation
  1. Install glow plug and tighten to 19 Nm (14 lb-ft).
  1. Connect glow plug electrical connector. Make sure glow plug wiring is routed to avoid moving parts.
--------------------------------------------------------------
Glow Plug Control Glow plugs are used to warm the cylinders to improve cold-engine starting. The PCM uses the engine oil temperature (EOT) sensor and barometric pressure (BARO) sensor to determine how long the glow plugs will be on. The PCM energizes the glow plugs longer if the engine is very cold or if the barometric pressure is low at high altitudes.
The PCM controls the relay that supplies power to the glow plugs with the glow plug control (GPC) signal. When the GPC signal is grounded by the PCM the relay closes, turning the glow plugs on.
The glow plugs are controlled by the following sequence:
  1. PCM energizes the glow plugs.
  1. The PCM energizes the glow plugs immediately after the ignition is placed in the ON position.
  1. The PCM then determines how long glow plugs will be on based on EOT sensor and the BARO sensor. The required time to warm up the cylinder decreases the engine oil temperature and barometric pressure increases at low altitudes.
Glow Plug Lamp Control The glow plug lamp (GPL) signal controls the WAIT TO START light located on the instrument panel. This light is used to indicate when to start the engine. The cylinders are being warmed by the glow plugs during and after this light is lit. The PCM energizes the glow plug lamp longer if the engine is very cold or if the barometric pressure is low.
When the GPL signal is brought low, the "Wait to Start" lamp is turned on.
The glow plug lamp is controlled by the following sequence:
  1. PCM lights the WAIT TO START light after a key on reset occurs.
The PCM determines the glow plug lamp activation time based on engine oil temperature, barometric pressure and battery voltage.
  1. PCM turns off the WAIT TO START light.
The glow plug lamp is turned off when the timer counts to the number of seconds specified by the PCM. The glow plugs will normally remain on longer than the "Wait to Start" lamp.
