Electronic Speed Sensor Module Test
- Number harness terminals from 1 to 6 (or 8), starting with terminal 1 nearest the locator key. With ignition switch "ON", connect negative voltmeter lead to ground and touch positive lead, in turn, to terminals 1, 4, and 6. Battery voltage should be indicated at terminals 1 and 4. Terminal 6 should be 6-8 volts.
- If voltage is less than 6 volts, service harness as necessary. If all tests are satisfactory, and problem still remains, replace electronic speed sensor module.
