|
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:
• 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.
• Is the voltage normal?
(See PCM INSPECTION [L8, LF, L5].)
(See PCM INSPECTION [MZR-CD 2.2].)
|
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.
