(1) Disconnect PCM connector C-91.
(2) Turn the ignition switch to the "ON" position and the 

auto-cruise control main switch to the "ON" position.

(3) Measure the voltage between PCM connector C-91 

harness side connector terminal 79 and ground.

• Voltage should measure between 4.0 and 5.5 volts.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Are the voltage within specifications?

YES : Replace the PCM. Then go to Step 10 .
NO :  Go to Step 6 .
