Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded on the repair order?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.
•  If the vehicle is not repaired, go to the next step.

•  Disconnect the TR switch connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion)
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 7.
No
Go to the next step.
4
INSPECT TR SWITCH SIGNAL CIRCUIT FOR SHORT TO GND
•  Switch the ignition off.
•  Inspect for continuity between TR switch terminal C (wiring harness-side) and body GND.
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to GND, then go to Step 7.
No
Go to the next step.
5
INSPECT TR SWITCH
•  Inspect the TR switch.
•  Is there any malfunction?
Yes
Replace the TR switch, then go to Step 7.
(See TRANSAXLE RANGE (TR) SWITCH REMOVAL/INSTALLATION [FN4A-EL].)
No
Go to the next step.
6
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Switch the ignition off.
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion)
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to the next step.
No
Go to the next step.
7
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all the disconnected connectors.
•  Clear the DTC using the M-MDS.
•  Perform the following procedure to ensure that the DTC has been resolved:
1.  Start the engine.
2.  Verify that input voltage from battery (PID item: VPWR) is 9 V or more.
3.  Idle the engine for 5 s or more.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [FN4A-EL].)
No
Go to the next step.
8
VERIFY NO DTCs ARE PRESENT
•  Perform the “Reading DTCs Procedure”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [FN4A-EL].)
No
DTC troubleshooting completed.
