3.
Measure the voltage between the O/D control terminal of the cruise control unit connector and ground.
Is there approx. 1V?
YES - Go to step 4.
NO - Replace the cruise control unit.

Before troubleshooting :
Check the ECM(10A), Horn(10A), ECU #3(10A) and ECU B+(15A) fuse in the under - hood fuse/relay box.
Check that the horn sounds.
Check the tachometer to see if it works properly.

Start the engine.
Turn on the cruise control main switch, then drive the vehicle to speeds over 25 mph (40km/h) with the cruise control.
Does the cruise control operate ?
YES - Go to step 3.
NO - Check the cruise control unit or cruise control actuator.
Measure the voltage between the O/D control terminal of the cruise control unit connector and ground.
Is there approx. 1V?
YES - Go to step 4.
NO - Replace the cruise control unit.
Measure the voltage between the cruise control terminal of the TCM(or PCM) connector and ground.
Is there approx. 1V?
YES - Check for loosen connectors. If necessary replace the TCM and recheck. (See Page TR group-automatic transaxle)
NO - Repair short or open in the wire between the TCM (or PCM) terminal and cruise control unit.
