―  Starter relay terminal A—Keyless control module terminal 4B
―  Starter relay terminal E—Keyless control module terminal 4AA
―  Starter relay terminal E—Starter interlock switch terminal A
MZR-CD 2.2
―  Starter relay terminal E—Keyless control module terminal 4B
―  Starter relay terminal A—Keyless control module terminal 4AA
―  Starter relay terminal A—Starter interlock switch terminal A
•  Keyless control module malfunction

Diagnostic Procedure

Step

Inspection

Action

1
INSPECT STARTER RELAY
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Remove the starter relay.
•  Inspect the starter relay.
•  Is there any malfunction?
Yes
Replace the starter relay, then go to Step 5.
No
Install the starter relay, then go to the next step.
2
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 5.
No
Go to the next step.
3
INSPECT STARTER RELAY CIRCUIT FOR SHORT TO POWER SUPPLY
•  Reconnect the negative battery cable.
•  Measure the voltage at the following terminals (wiring harness-side):
―  Starter relay terminal A
―  Starter relay terminal E
•  Is there any voltage?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to Step 5.
No
Go to the next step.
4
INSPECT KEYLESS CONTROL MODULE
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Make sure to reconnect the disconnected connectors.
•  Remove the starter relay.
•  Reconnect the negative battery cable.
•  Measure the voltage at the keyless control module terminal 4B (wiring harness-side) with the clutch not depressed.
•  Is the voltage more than 6 V?
Yes
Replace the keyless control module, then go to the next step.
No
Go to the next step.
5
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from the keyless control module using the M-MDS.
•  Switch the ignition to off.
•  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.
6
VERIFY THAT NO OTHER DTCs ARE PRESENT
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
