Hall Sender
- Remove instrument cluster. Connect voltmeter between Red wire and Black wire on Hall Sender. Turn ignition switch to "ON" position and measure voltage. Voltmeter should read 9.75-10.2 volts. If not, replace voltage stabilizer and connect voltmeter between Black wire and Green wire on Hall Sender.
- Turn speedometer clockwise using a square key. Voltmeter should have pulsating readings of zero volts to 8-10 volts and back to zero volts. If not, replace Hall Sender and repeat test. If Hall Sender checks good, replace cruise control computer module.
