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 VOLTAGE OF STARTER LOCK OUTPUT SIGNAL CIRCUIT
• Switch the ignition ON (Engine off).
• Shift the selector lever to P or N position.
• Inspect for voltage TCM connector terminal A5 (wiring harness-side).
• Is the voltage 0 V?
|
Yes
|
Go to go to Step 5.
|
No
|
Go to the next step.
|
||
4
|
INSPECT TCM CONNECTOR FOR POOR CONNECTION
• Disconnect the TCM connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Are terminals normal?
|
Yes
|
Go to Step 10.
|
No
|
Replace the couple component, then go to Step 10.
|
||
5
|
INSPECT VOLTAGE OF STARTER LOCK OUTPUT SIGNAL CIRCUIT
• Shift the selector lever to D position or R position.
• Inspect for voltage TCM connector terminal A5 (wiring harness-side).
• Is the voltage B+?
|
Yes
|
Go to go to Step 10.
|
No
|
Go to the next step.
|
||
6
|
INSPECT PCM FOR POOR CONNECTION
• Switch the ignition OFF.
• Disconnect the PCM connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Are terminals normal?
|
Yes
|
Go to the next step.
|
No
|
Replace the couple component, then go to Step 10.
|
||
7
|
INSPECT STARTER LOCK OUTPUT SIGNAL CIRCUIT FOR OPEN CIRCUIT
• Inspect for continuity between TCM connector terminal A5 and PCM terminal 1Q (wiring harness-side).
• Is there continuity?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the harness, then go to Step 10.
|
||
8
|
INSPECT STARTER LOCK OUTPUT SIGNAL CIRCUIT FOR SHORT TO GROUND
• Inspect for continuity between PCM terminal 1Q (wiring harness-side) and body ground.
• Is there continuity?
|
Yes
|
Repair or replace the harness, then go to Step 10.
|
No
|
Go to the next step.
|
||
9
|
INSPECT STARTER LOCK OUTPUT SIGNAL CIRCUIT FOR SHORT TO POWER
• Switch the ignition ON (Engine off).
• Inspect the voltage at PCM terminal 1Q (wiring harness-side).
• Is the voltage 0 V?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the wiring harness, then go to the next step.
|
||
