OK: Go to next step 

1. Disconnect the camshaft timing oil control valve (for exhaust camshaft) connector.
2. Disconnect the ECM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance (Check for open)

   Tester Connection	Condition	Specified Condition
   A36-7 (OE1) - C5-2	Always	Below 1 Ω
   A36-5 (OE2) - C23-2	Always	Below 1 Ω

   Standard Resistance (Check for short)

   Tester Connection	Condition	Specified Condition
   A36-7 (OE1) or C5-2 - Body ground	Always	10 kΩ or higher
   A36-5 (OE2) or C23-2 - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   9 

1. Inspect the EFI MAIN1 relay. Refer to ON-VEHICLE INSPECTION [07/2013 - ] - Step 1 .

NG → REPLACE RELAY (EFI MAIN1) 

OK: Go to next step 

1. Disconnect the ECM connector.
2. Remove the EFI MAIN1 relay from the engine room relay block assembly.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance (Check for open)

   Tester Connection	Condition	Specified Condition
   EFI MAIN1 relay terminal 3 - C5-1	Always	Below 1 Ω
   EFI MAIN1 relay terminal 3 - C23-1	Always	Below 1 Ω

   Standard Resistance (Check for short)

   Tester Connection	Condition	Specified Condition
   EFI MAIN1 relay terminal 3 or C5-1 - Body ground	Always	10 kΩ or higher
   EFI MAIN1 relay terminal 3 or C23-1 - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   10
