Diagnostic Procedure

Step

Inspection

Action

1
INSPECT CPP SWITCH CONNECTOR CONDITION
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Disconnect the CPP switch connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 12.
No
Go to the next step.
2
INSPECT CPP SWITCH GROUND CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between CPP switch terminal B (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 12.
3
INSPECT CPP SWITCH
•  Is there any malfunction?
Yes
Replace the CPP switch, then go to Step 12.
No
Go to the next step.
4
INSPECT STARTER INTERLOCK SWITCH CONNECTOR CONDITION
•  Disconnect the starter interlock switch connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 12.
No
Go to the next step.
5
INSPECT STARTER INTERLOCK SWITCH
•  Is there any malfunction?
Yes
Replace the starter interlock switch, then go to Step 12.
No
Go to the next step.
6
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 12.
No
Go to the next step.
7
INSPECT KEYLESS CONTROL MODULE CONNECTOR CONDITION
•  Disconnect the keyless control module connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 12.
No
Go to the next step.
8
INSPECT STARTER RELAY CIRCUIT FOR SHORT TO GROUND
•  Inspect for continuity between the following terminals and body ground:
―  Starter relay terminal E (wiring harness-side)
―  Starter relay terminal A (wiring harness-side)
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to ground, then go to Step 12.
No
Go to the next step.
9
INSPECT STARTER RELAY CIRCUIT FOR SHORT TO GROUND
•  Inspect for continuity between starter interlock switch terminal B (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to ground, then go to Step 12.
No
Go to the next step.
10
INSPECT PCM
•  Reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Switch the ignition to ON.
•  Measure the voltage between PCM terminal 1BB (wiring harness-side) and body ground.
Yes
Go to the next step.
No
Replace the PCM, then go to Step 12.
11
INSPECT KEYLESS CONTROL MODULE
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Remove the starter relay.
•  Reconnect the negative battery cable.
•  Measure the voltage between keyless control module terminal 4AA (wiring harness-side) and body ground with the clutch depressed:
•  Is the voltage more than 4 V?
Yes
Go to the next step.
No
Replace the keyless control module, then go to the next step.
12
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from keyless control module memory using the M-MDS.
•  Perform the advanced keyless entry and push button start system DTC inspection using the M-MDS.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
If the malfunction recurs, replace the keyless control module, then go to the next step.
No
Go to the next step.
13
VERIFY THAT NO OTHER DTCs ARE PRESENT
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
