(2) Measure the voltage between terminal No. 60 <M/T> or No. 

66 <A/T> and ground.

• Voltage should be battery positive voltage.

Q: Is battery positive voltage (approximately 12 volts) 

present?
YES : Go to Step 7.
NO :  Check harness connector C-07 at intermediate 

connector for damage, and repair or replace as 
required. Refer to, GROUP 00E, Harness Connector 
Inspection 

P.00E-2

. If intermediate connectors are in 

good condition, repair harness wire between fusible 
link (3) and ECM connector C-58 (terminal No. 60) 
<M/T> or PCM connector C-55 (terminal No. 66) 
<A/T> because of open circuit. Then confirm that the 
malfunction symptom is eliminated.

STEP 7. Check the continuity at ECM harness side 
connector C-58 <M/T> or PCM harness side connector 
C-55 <A/T>.
(1) Disconnect the connector C-58 <M/T> or C-55 <A/T> and 

measure at the harness side.

(2) Check for the continuity between terminal (No. 46, No. 58) 

<M/T> or (No. 42, No. 48) <A/T> and ground.

• Should be less than 2 ohm.

Q: Is the continuity normal?

YES : Go to Step 8.
NO :  Repair harness wire between ECM connector C-58 

(terminals No. 46, No. 58) <M/T> or PCM connector 
C-55 (terminals No. 42, No. 48) <A/T> and ground 
because of open circuit or harness damage. Then 
confirm that the malfunction symptom is eliminated.
