Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY IMMOBILIZER SYSTEM DTC
•  Verify the immobilizer system DTC.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)
(See DTC TABLE [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND START SYSTEM)].)
No
Go to the next step.
4
CHECK FOR ANY OTHER POWERTRAIN DTC
•  Verify the pending code or stored DTCs using the M-MDS.
•  Are all other powertrain DTCs diagnosed?
Yes
Go to the next step.
(The system is operating normal at this time. The concern may have been caused by a loose or corroded connector.)
No
Go to the appropriate DTC troubleshooting procedures.
(See DTC TABLE [MZI-3.7 (PCM CONNECTOR (3 TYPES))].)
5
ATTEMPT TO START ENGINE
•  Complete the keep alive memory.
•  Reset to clear DTC P1260:00.
•  This reset initializes the PCM to communicate with the immobilizer system.
•  Attempt to start the engine.
•  Does the engine start?
Yes
No system malfunctions exists at this time.
For intermittent No Starts or Start Stalls, verify intermittent PATS faults.
Then go to the next step.
Note
•  PATS cannot stall the engine after 1 second of operation. For intermittent Stalls while driving, verify the M-MDS tester to PCM communication during concern. If a PCM communication error occurs, possible causes are:
―  Loss of PWRS or grounds to the PCM
―  Malfunctioning PCM PWR relay
―  Malfunctioning EEC PWR diode
•  Repair if necessary and return the vehicle to customer.
No
DTC P1260:00 is not the cause of the No Start.
(See QUICK DIAGNOSTIC CHART [MZI-3.7].)
6
VERIFY TROUBLESHOOTING OF DTC P1260:00 HAS BEEN COMPLETED
•  Verify that all disconnected connectors are reconnected.
•  Turn the ignition switch to the ON position (Engine off).
•  Clear the DTC from the PCM memory using the M-MDS.
•  Retrieve DTCs using the M-MDS.
•  Is the PENDING CODE for this DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
