Solution:
Turn off the engine.
Disconnect the injector and coil pack multi-plugs and proceed to step 1 of the test below.

Test:
•1. Ensure that injector harness pin 1 continuity is correctly wired to PI 119/005. If the result is positive, proceed to step 2. If the circuit is open, locate and correct the wiring fault, reconnect the harness and proceed to step 13.
•2. Ensure that the harness continuity of each injector pin 2 is correctly wired to the GEMS ECM connection. If the result is positive, proceed to step 3. If the circuit is open, locate and correct the wiring fault, reconnect the harness and proceed to step 13.
•3. Ensure that the harness continuity of each coil pin 1 is correctly wired to the GEMS ECM connection. If the result is positive, proceed to step 4. If the circuit is open, locate and correct the wiring fault, reconnect the harness and proceed to step 13.
•4. Ensure that the harness continuity of each coil pin 1 is correctly wired to RS 001/010. If the result is positive, proceed to step 5. If the circuit is open, locate and correct the wiring fault, reconnect the harness and proceed to step 13.
•5. Ensure that the harness insulation of each injector pin 1 is correctly grounded. If this gives a positive result, proceed to step 6. If there is a short circuit, locate and correct the wiring fault, reconnect the harness and proceed to step 13.
•6. Ensure that the harness insulation of each injector pin 2 is correctly grounded. If the result is positive, proceed to step 7. If there is a short circuit, locate and correct the wiring fault, reconnect the harness and proceed to step 13.
•7. Ensure that the harness insulation of each coil pin 1 is correctly grounded. If the result is positive, proceed to step 8. If there is a short circuit, locate and correct the wiring fault, reconnect the harness and proceed to step 13.
•8. Ensure that the harness insulation of each coil pin 2 is correctly grounded. If the result is positive, proceed to step 9. If there is a short circuit, locate and correct the wiring fault, reconnect the harness and proceed to step 13.
•9. Check the voltage reading between each injector pin 2 connector and PI 119/005. If it reads 0 V, proceed to step 10. If it reads Vbatt, locate and correct the wiring fault, reconnect the harness and proceed to step 13.
•10. Check the voltage reading of each injector pin 1 connector and PI 119/005. If it reads 0 V, reconnect the harness and proceed to step 11. If the reading is Vbatt, locate and correct the wiring fault, reconnect the harness, reconnect the injector, coil and harness and proceed to step 13.
•11. Ensure that the fuel pump pressure is between 3 and 4 bar (absolute) and that it changes according to engine load. If this gives a positive result, proceed to step 12. If the pressure is out of range, correct it and proceed to step 13.
•12. Check if the crankshaft position sensor fault code has been recorded. If not, proceed to step 13. If it is faulty, correct it and proceed to step 13.

The Direct Ignition System (DIS) is a 1-cylinder ignition system that fires one cylinder with one ignition coil. The igniter is an integral part of the ignition coil. The Engine Control Module (ECM) determines ignition timing and outputs an ignition signal (IGT) for each cylinder. Based on the IGT signals, the power transistors in the igniter cut off current to the ignition coil primary coil, causing the ignition coil to fire the spark plug. After giving the command to deactivate the primary circuit on the IGT wire, the ECM monitors the IGF circuit to ensure that primary switching has occurred.

What Does Buick Code P1315 Mean?

The Diagnostic Trouble Code (DTC) P1315 ignition coil primary feedback circuit monitors the primary circuits of individual ignition coils to ensure the success of an ignition event. The ignition trigger signal and the ignition safety input signal provide crucial information for controlling the ignition system timing and activating the safety function. Based on the initial timing angle, calculated from the crankshaft and camshaft position signals, the Powertrain Control Module (PCM) calculates the ignition trigger signal. The ignition trigger signal is then sent to the ignition control circuit located in each ignition coil. The ignition control circuits initiate the ignition dwell period by commanding the power transistor ON. When the PCM determines the appropriate time to provide a spark, the PCM turns off the ignition trigger signal. In response to the PCM signal, the ignition coil control circuit cuts off the power transistor, producing a high-voltage discharge from the secondary coil windings. After a spark has occurred, the control circuit sends an ignition safety input signal back to the PCM, confirming that an ignition event has taken place. If the ignition safety input signal is not received by the PCM, a cylinder-specific DTC will be set.

Whenever the safety input signal is lost, engine operation switches to a safety function. If the engine load exceeds certain parameters during the safety function, FUEL CUT-OFF mode is activated, and the fuel injector operation is interrupted. Suspending fuel injection in FUEL CUT-OFF mode protects the catalytic converter from damage. Damage can occur when excess unburned fuel reaches the converter and causes the catalyst to overheat.

What does Jaguar P1315 code mean?

The misfire monitor operates continuously and is designed to detect misfire levels that could cause thermal damage to the catalyst or excessive exhaust emissions. Misfire determination is done by analyzing crankshaft speed changes, since a misfire will cause a speed drop. Essentially, the monitor determines the time required for the crankshaft to travel 180 degrees (4 cylinders only) for the current firing event and compares it to the time required for the previous firing event. If the time required for the “current” firing is longer than the previous firing, then a misfire is considered to have occurred.
