Diagnostic Procedure

Step Inspection Action
1 INSPECT FUSE 
  • Switch the ignition to off.
  • Disconnect the negative battery cable.
  • Remove the ST SIG 5 A fuse.
  • Inspect the ST SIG 5 A fuse.
  • Is there any malfunction?
 Yes Replace the ST SIG 5 A fuse, then go to Step 6.
No Go to the next step.
2 INSPECT RELAY 
  • Remove the starter relay.
  • Inspect the starter relay.

    (See RELAY INSPECTION .)

  • Is there any malfunction?
 Yes Replace the starter relay, then go to Step 6.
No Go to the next step.
3 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 6.
No Go to the next step.
4 INSPECT STARTER RELAY CIRCUIT FOR OPEN CIRCUIT 
  • Install the ST SIG 5 A fuse.
  • Install the starter relay.
  • Inspect for continuity between the following terminals:
    • Starter relay terminal E (wiring harness-side) and keyless control module terminal 4B (wiring harness-side)
    • Starter relay terminal A (wiring harness-side) and keyless control module terminal 4AA (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 Step 6.
5 INSPECT KEYLESS CONTROL MODULE 
  • Reconnect the disconnected connectors.
  • Reconnect the negative battery cable.
  • Bring the valid key into the vehicle.
  • Measure the voltage between the following terminals and body ground with the shift lever in P range:
    • Keyless control module terminal 4B (wiring harness-side)
    • Keyless control module terminal 4AA (wiring harness-side)
  • 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.
(See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] .)
6 VERIFY TROUBLESHOOTING COMPLETED
