Question about 2007 Acura MDX

1 Answer

Car won't start and displays check starting system. Engine does not crank or make a sound when key is engaged to start. Dealer can't figure out what to do nor tech support from Acura

Replaced the ECM hard drive, starter relays, and brake switch. It is an intermittent problem but has been reproduced at the dealer and is becoming more frequent. Code P0615 starter cut relay drive circuit malfunction is all that shows up.

    Were you able to solve this issue? I am getting the Check Starter System sign on since yesterday and wanted to know more about this. My car starts as I press the start button for few sec.

    My 07 NFC does this every once in a while. I take it out of park and put it in neutral and then it will start.

WOW BEING 4 QUARTS LOW CAN'T BE GOOD FOR THE ENGINE. BUT ANYWAY YOU CAN TRY TO SEE IF THE FUEL PUMP FUSE AND RELAY ARE GOOD. IF THEY ARE THEN THIS FUEL PUMP REPLACEMENT IS FAIRLY SIMPLE. HOPE THIS HELPS YOU WITH THE FUEL ISSUE. GOOD LUCK. KEEP ME POSTED PLEASE. I HAVE TO KNOW IF THIS ENGINE STILL RUNS. THANKS FOR USING FIX-YA

looked it up online, looks like its in the underhood fuse box but couldn't get a good diagram that shows which relay number it is. the website i use is sort of dependent on the manufacturer, apparently acura did not feel like sharing that info. hope that helps

I doubt they did anymore damage but i`ll bet that the engine was damaged from the training going out such as valve guides and seals and carbon build up on plugs ETC.

SOURCE: car wont start got a starter but its the relay switch

STARTER RELAY IS UNDER THE HOOD AND UNDER THE DASH.IT COULD BE THE STARTER SOLENOID ON STARTER BAD.IT WILL CAUSE NO CRANKING PROBLEMS.

SOURCE: my 97 Acura CL 3.0liter stopped turning over.

Sounds as though you changed parts unrelated to the engine turning over. The ign module etc would be where you would check, if you had no spark.
Do you really know that the ignition switch is okey
Do you know that the neutral switch is adjusted correctly if that applies or is in fact working okey.
All relays may click,BUT are their contacts inside burn't,and not completing a circuit ,the the starter solenoid?
If you had a wiring diagram in the beginning,it sounds as though,you know what your doing and would be closer to solving the issuse

My 2007 Uplander won't start. We've replaced to battery and starter relay. Still won't even click when trying to start.


How to voltage drop test starter motor circuit This is how a normal starting system use to work ! Not now , computer's involved , communication networks etc.....
Here is how your's works

For ignition switch power modes refer to Body Control System Description and Operation . When the ignition switch is placed in the Start position a discrete signal is supplied to the body control module (BCM) notifying it that the ignition is in the Start position. The BCM then sends a message to the engine control module (ECM) notifying it that CRANK has been requested. At the same time the BCM is supplying 12 volts for the IGN 1 relay closing it and supplying battery positive voltage for the crank relay coil. The ECM verifies that the transmission is in Park or Neutral. If it is, the ECM grounds the control circuit of the crank relay. When this occurs battery positive voltage is supplied through the switch side of the crank relay to the S terminal of the starter solenoid.

Sorry but your best bet would be to take it to a qualified repair shop ! Or the Chevy dealer . Could have DTC'S - diagnostic trouble codes stored in the BCM !

DTC P0615 Starter Relay Control Circuit

Circuit/System Verification
Ignition ON, verify that no starter relay, theft deterrent, or automatic transmission DTCs are set that would cause the ECM to disable starting.
? If DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle .
Ignition ON, observe the scan tool BCM Starter Switch parameter. Place ignition switch in the crank position, the parameter should display ON.
? If not the specified value, refer to Power Mode Mismatch .
Transmission range selector in park , verify the scan tool ECM PNP Switch and TCM IMS parameters display Park/Neutral.
? If the TCM IMS parameter does not indicate Park/Neutral, refer to Transmission Internal Mode Switch Logic .
? If the ECM Park/Neutral parameter does not indicate Park/Neutral, refer to ECM Park Switch Circuit Malfunction.
Transmission range selector in park or neutral, attempt to start the vehicle. The starter relay should click and the engine should begin cranking.
? If the starter relay does not click or the engine does not crank, refer to Starter Relay Circuit Malfunction.

Power to many of this vehicle's circuits are controlled by the module that is designated the Power Mode Master (PMM). This vehicle's PMM is the Body Control Module (BCM). The PMM controls which power mode (Run, Accessory, Crank, Retained Accessory Power, or Off) is active.

Serial Data Power Mode
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits. The table below illustrates the state of these inputs in correspondence to the ignition switch position:

'07 yukon 24k. it wont start/crank/no pwr took to the dealer they said it has to be acting up for them to troubleshoot. happened again so i had it towed to the dealer but they couldnt find problem


I would need the car for as long as it takes to duplicate the problem, you can't fix what is not wrong when the car is in for repair. I suggest you leave it with a good shop until it acts up.

What is csusing an intermittent starting problem with my Elantra?


If the starter motor won't crank, then check voltage and ground circuits at the starter motor, when problem is ongoing. Any testing at the starter motor, make sure tranny is in park or neutral and the parking brake is set.
Unless you can do some testing, I'm not sure how to help?

Car turns over but won't stay on??


There is no magic button fix. Begin by doing a readout of stored codes from the ECU. Proceed by replacing fuel filter (usually corrects the condition), verifying correct pressure at the fuel rail, servicing the fuel pressure regulator and fuel pump assembly as necessary, and proceed to verifying spark and operation of the ignition system.

Your ignition switch supplies power to the start relay, Which is grounded by the engine control module(ECM). The ignition switch also sends a signal to the ECM that it is in crank mode, Which causes the ECM to ground the relay, this turns the starter. You have three possibilities, two are wiring, the other is a bad ECM. Both wires are to the ECM from the ignition switch. One is shorted to a hot wire, the other is shorted to ground. The ECM is just shorted to either. My first guess is the the ECM. I would pull it, take the case off the PC boards and clean them. Brake clean is good and a soft brush. Any corrosion will look white to a light green. Especially around the leads/plugs. Also check the plugs. Once this is checked or done, I would go to the wires. Continuity check, power and ground checks. A volt/ohm meter is required. I am sending a picture of wiring, it's for a 2003 GM. This is how they work, but it won't match your color codes. If you want exact, go to alldatadiy.com and you can purchase it.

When you say it won't start, do you mean it cranks but won't fire, or it just won't crank? If it just won't crank, you could be having an issue with the starter relay. The often become intermittent before failure. Many owners do not know there is a starter relay because it was added as a recall item i order to protect the iginition switch from burnout. The starter relay is located in the very front of the engine compartment, just to the left of the battery, on the back side of the radiator crossmember.

My car does not start or turn over. The radio works and so does the fan.


When you turn the ignition key to start your car, voltage from the battery flows through the ignition switch to the Park/Neutral safety switch and/or brake pedal or clutch pedal safety switch (you have to push the pedal down before the circuit will complete) to the starter relay or solenoid. When the relay or solenoid is energized by voltage from the ignition switch circuit, it closes a contact that routes more power from the battery directly to the starter to crank the engine. The starter motor spins, pushes the starter drive gear to engage the flywheel and cranks the engine.

Low battery (Check battery voltage, recharge if low, or jump start with another vehicle or battery charger).
Loose or corroded battery cables (Inspect, clean and tighten BOTH ends of BOTH battery cables).
Bad starter relay wiring connections or ground connection (Inspect, clean, tighten wiring connections).
Bad starter relay/solenoid (Check for voltage at relay, if relay has voltage but there is no "click" when key is turned to start, replace relay).
Bad starter (Jump battery voltage direct to starter to see if it spins, or remove starter and have it bench tested at auto parts store).
Damaged starter drive or teeth on flywheel (Remove starter and inspect drive gear and flywheel teeth, replace damaged parts if necessary).
Bad ignition switch (Check to see if voltage reaches starter relay/solenoid when turn to start. If not, check for open P/N switch and brake or clutch pedal switch. Replace ignition switch if defective).
Open P/N safety switch, or open Brake Pedal Safety Switch (automatic transmission) or open Clutch Pedal Switch (manual transmission). Bypass switch with jumper wire to see if engine cranks, or use test light or voltmeter to check for voltage passing through switch when ignition is turned to start.
Engine seized due to bearing failure or internal damage (Use socket and long handle to see if engine can be turned by hand, if not engine is locked up).
Engine hydrolocked due to coolant leak from leaky head gasket (Use socket and wrench to see if engine rotates, remove spark plugs and see if coolant comes out or engine can not be cranked with plugs out).

Try having someone watch ur lights as you tilt the steering wheel in different positions and pressing on the brake in each tilt position. Sounds strange but the brake light go through teh wiring in the steering column. I drive with my wheel tilted higher than normal to keep BOTH brake lights working.

Check the number on the ECM . If it has the number 1228253 on it that is your problem. They had a cutting off problem while driving. Get one with the number 16198264 on it. The 1228253 is junk and gm replaced them with 16198264.
