DIAGNOSTICS PROCEDURE

Step Check Yes No
1 CHECK LAN SYSTEM. 
Inspect LAN system. < Ref. to PROCEDURE , Basic Diagnostic Procedure. >		 Is LAN system normal? Go to step 2  . Perform the inspection according to the diagnosis for LAN system.
2 CHECK HARNESS. 
  1. Disconnect the keyless access control module connector and ECM connector.
  2. Using a tester, measure the resistance between the keyless access control module connector and ECM.

    Connector & terminal 

    (i241) No. 36 - (B134) No. 64: 

 Is the resistance less than 1 Ω? Go to step 3  . Repair or replace the open circuit of harness.
3 CHECK HARNESS. 
Using a tester, measure the resistance between the keyless access control module connector and chassis ground.
Connector & terminal 
(i241) No. 36 - Chassis ground: 		 Is the resistance 10 kΩ or more? Go to step 4  . Repair or replace the short circuit of the harness.
4 CHECK HARNESS. 
Using a tester, measure the resistance between the keyless access control module connector and chassis ground.
Connector & terminal 
(i241) No. 21 - Chassis ground: 
(i75) No. 1 - Chassis ground: 		 Is the resistance less than 1 Ω? Go to step 5  . Repair or replace the open circuit of harness.
5 CHECK KEYLESS ACCESS CONTROL MODULE. 
  1. Connect the keyless access control module connector and ECM connector.
  2. Place the access key in the passenger room.
  3. Using a tester, measure the voltage between terminals of the keyless access control module connector when the push button ignition switch is pressed while depressing the brake pedal, with the shift lever in the P range for model except for MT or while depressing the clutch pedal for MT model.

    Connector & terminal 

    (i241) No. 36 (+) - (i241) No. 21 (-): 

 Is the voltage 9.5 - 16 V → 1 V or less? Replace the keyless access control module. < Ref. to KEYLESS ACCESS CONTROL MODULE . > Replace the ECM. < Ref. to REMOVAL , Engine Control Module (ECM). > < Ref. to REMOVAL , Engine Control Module (ECM). >
