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.
No
Go to the next step.
3
INSPECT TR SWITCH CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to off.

•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 8.
No
Go to the next step.
4
INSPECT TR SWITCH CIRCUIT FOR SHORT TO POWER SUPPLY
•  Switch the ignition to ON (Engine off).
•  Measure the voltage between TR switch terminal C (wiring harness-side) and body GND.
•  Is the voltage B+?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to Step 8.
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 8.
No
Go to the next step.
6
INSPECT TCM CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to off.
•  Disconnect the TCM 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 8.
No
Go to the next step.
7
INSPECT TR SWITCH CIRCUIT FOR OPEN CIRCUIT
•  Switch the ignition to off.
•  Inspect for continuity between the following circuits:
―  TR switch terminal C (wiring harness-side) and TCM terminal 2H (wiring harness-side)
―  TR switch terminal B (wiring harness-side) and TCM terminal 2O (wiring harness-side)
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to the next step.
8
VERIFY TROUBLESHOOTING OF DTC P0708:00 COMPLETED
•  Make sure to reconnect all the disconnected connectors.

1.  Drive the vehicle at more than 8 km/h {5 mph} for 5 s or more.
•  Is the same DTC present?
Yes
Replace the TCM, then go to the next step.
No
Go to the next step.
9
VERIFY NO DTC HAS BEEN PRESENTED
