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: GO TO NEXT STEP 

   STA SIGNAL
   
   

   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 E7 ECM connector while cranking the engine (ignition switch is in the START position).

   Standard voltage 

   ECM (STA AND STSW VOLTAGE) (1 OF 2)
   
   

   Tester Connection	Specified Condition
   E7-11 (STA) - E7-1 (E1)	9 to 14 V
   E7-12 (STSW) - E7-1 (E1)	9 to 14 V

   Result 

   ECM (STA AND STSW VOLTAGE) (2 OF 2)
   
   

   Terminal STSW	Terminal STA	Proceed to
   9 to 14 V	9 to 14 V	A
   9 to 14 V	0 V	B
   0 V	0 V	C

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 in PARK/NEUTRAL POSITION SWITCH  when the shift lever is moved to each position.

   Standard resistance 

   PARK/NEUTRAL POSITION SWITCH
   
   

   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 

   STARTER RELAY
   
   

   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 

   ENGINE ROOM RELAY BLOCK (STARTER RELAY VOLTAGE)
   
   

   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) 

OK: GO TO NEXT STEP 

1. Inspect starter assembly (see INSPECTION ).

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 IGNITION SWITCH ASSEMBLY  .

   Standard resistance 

   IGNITION SWITCH ASSEMBLY
   
   

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

3. Reconnect the I18 ignition switch connector.

NG: REPLACE IGNITION SWITCH ASSEMBLY 

OK: CHECK AND REPAIR HARNESS OR CONNECTOR (ECM - IGNITION SWITCH, IGNITION SWITCH - BATTERY)
