STEP 3. Check the signal voltage at PCM connector C-57
<2.4L Engine> or C-59 <3.0L Engine> by backprobing.
(1) Do not disconnect connector C-57 <2.4L Engine> or C-59

<3.0L Engine>.

(2) Turn the ignition switch to "ON" position.

(3) Measure the voltage between terminal 75 and ground by

backprobing.

•

Voltage should be battery positive voltage.

(4) Turn the ignition switch to "LOCK" (OFF) position.

Q: Is the voltage normal?

YES : Go to Step 5.
NO : Go to Step 4.

STEP 4. Check connectors C-57 <2.4L Engine> or C-59
<3.0L Engine> at PCM and C-28 at inter mediate connector
for damage.
Q: Are the connectors in good condition?

YES : Replace the PCM.
NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 5. Check the signal voltage at auto-cruise control-
ECU connector C-20 by backprobing.
(1) Do not disconnect connector C-20.
(2) Turn the ignition switch to "ON" position.

(3) Measure the voltage between terminal 3 and ground by

backprobing.

•

Voltage should be battery positive voltage.

(4) Turn the ignition switch to "LOCK" (OFF) position.

Q: Is the voltage normal?

YES : Go to Step 7.
NO : Go to Step 6.

STEP 6. Check harness for short circuit to ground, open
circuit or damage between PCM connector C-57 <2.4L
Engine> or C-59 <3.0L Engine> terminal 75 and auto-cruise
control-ECU connector C-20 terminal 3.
Q: Is the harness wire in good condition?

YES : Go to Step 7.
NO : Repair it.
