(2) Measure the voltage between terminal No. 80 <M/T> or No.

66 <A/T> and ground by backprobing.

• Voltage should be battery positive voltage.

Q: Is battery positive voltage (approximately 12 volts)

present?
YES : Go to Step 5.
NO : Go to Step 3.

STEP 3. Measure the backup power supply voltage at ECM
harness side connector C-60 <M/T> or PCM harness side
connector C-54 <A/T>.
(1) Disconnect the ECM connector C-60 <M/T> or PCM

connector C-54 <A/T> and measure at the harness side.

(2) Measure the voltage between terminal No. 80 <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 4.
NO : Check 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 connector are in good

condition, repair harness wire between relay box (9)
and ECM connector C-60 (terminal No. 80) <M/T> or
PCM connector C-54 (terminal No. 66) <A/T>
because of open circuit or short circuit to ground.
Then go to Step 6.

STEP 4. Check connector C-60 at ECM <M/T> or connector
C-54 at PCM <A/T> for damage.
Q: Is the harness connector in good condition?

YES : Check 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 connector are in good

condition, repair harness wire between relay box (9)
and ECM connector C-60 (terminal No. 80) <M/T> or
PCM connector C-54 (terminal No. 66) <A/T>
because of harness damage. Then go to Step 6.

NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection
