EXHAUST BRAKE SOLENOID MALFUNCTION












1. CHECK THE VOLTAGE BETWEEN TERMINALS.
1. Set the starter switch to "LOCK" position and connect signal check harness.
2. Disconnect the check harness at the ECU side connector and turn the starter switch to "ON" position.
3. Measure the voltage between B2 and D1, E4, E5 terminals of ECU connector (ECU side).
4. Measure the resistance of insulation between terminals and SCV body.

Standard: More than 10 V












2. CHECK THE RESISTANCE BETWEEN TERMINALS OF MAGNETIC VALVE
1. Disconnect the connector of exhaust brake magnetic valve.
2. Measure the resistance between terminals of magnetic valve.

Standard: 13.5 ± 5 ohms
