Inspection Procedure

1. When turning the ignition switch to the START position check if the starter motor starts.

OK: CHECK FOR INTERMITTENT PROBLEMS 

NG: Go to next step 

1. Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
2. Enter the following menu: DIAGNOSIS / ENHANCED OBDII / DATA LIST / PRIMARY / STARTER SIG.
3. Confirm the starter signal status when the ignition switch is operated.

   OK 

   IGNITION SWITCH POSITION AND STARTER SIGNALS REFERENCE
   
   

   Ignition Switch Position	STARTER SIG
   ON	OFF
   Start	ON

OK: Go to step  5

NG: Go to next step 

1. Measure the voltage of the E6 ECM connector while cranking the engine (ignition switch is in the START position).

   Standard voltage 

   VOLTAGE SPECIFICATION
   
   

   Tester Connection	Specified Condition
   E6-11 (STA) - E6-1 (E1)	9 to 14 V
   E6-12 (STSW) - E6-1 (E1)	9 to 14 V

B: REPLACE ECM 

C: Go to step  9

A: Go to next step 

1. Disconnect the P1 park / neutral position switch connector.
2. Measure the resistance between each terminal shown below when the shift lever is moved to each position.

   Standard resistance 

   RESISTANCE SPECIFICATION
   
   

   Shift Position	Tester Connection	Specified Condition
   P or N	4 - 5	Below 1 Ω

3. Reconnect the park / neutral position switch connector.

NG: REPLACE PARK / NEUTRAL POSITION SWITCH

OK: CHECK AND REPAIR HARNESS OR CONNECTOR (PARK / NEUTRAL POSITION SWITCH - ECM) 

1. Remove the starter relay from the engine room relay block.
2. Measure the resistance of the starter relay.

   Standard resistance 

   RESISTANCE SPECIFICATION
   
   

   Tester Connection	Specified Condition
   3 - 5	10 kΩ or higher
   3 - 5	Below 1 Ω (when battery voltage applied to terminals 1 and 2)

3. Reinstall the starter relay.

NG: REPLACE STARTER RELAY

OK: Go to next step 

1. Check harness and connector (see ELECTRONIC CIRCUIT INSPECTION PROCEDURE ).

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Remove the STARTER relay from the engine room relay block.
2. Measure the voltage of the engine room relay block and body ground.

   Standard voltage 

   VOLTAGE SPECIFICATION
   
   

   Tester Connection	Specified Condition
   Engine room relay block (Starter relay terminal 5) - Body ground	9 to 14 V

3. Reinstall the STARTER relay.

NG: CHECK AND REPAIR HARNESS AND CONNECTOR (STARTER RELAY - BATTERY)

NG: REPAIR OR REPLACE STARTER ASSEMBLY 

OK: CHECK AND REPAIR HARNESS OR CONNECTOR (STARTER RELAY - STARTER, STARTER - BATTERY) 

1. Disconnect the I18 ignition switch connector.
2. Measure the resistance of the connector terminals shown in the chart below.

   Standard resistance 

   RESISTANCE SPECIFICATION
   
   

   Switch Position	Tester Connection	Specified Condition
   START	7 - 8	Below 1 Ω

3. Reconnect the I18 ignition switch connector.
