- Disconnect the instrument cluster connector.
- Engage the turn signal switch so that the RH turn indicator is
supposed to be on.
- Use a DMM in order to measure the voltage between terminal 18
of instrument cluster connector and a known good ground.
- When the turn signal switch is engaged, the voltage on the circuit
varies from 0 V to B+.
Does the voltage measure in the specified range?
| 0 V-B+
