(12) Heater Glow (V1505)
Connector Voltage
1. Disconnect the connector, and turn the main key switch "ON"
position.
2. Do active test "Catalyst Heater for Fuel Reformer ON / OFF
Function" by using diagmaster before following checking (Refer
to "Diagnosis Manual V1505-T-E4 (9Y120-02490)").
3. Measure the voltage with a voltmeter across the terminals
shown in the table below.
4. If the reference value is not indicated as shown in the table
below, check the relating electric circuit.

Heater Glow Continuity
• Since reformer is emission related critical parts, do not
remove the glow plug.
1. Remove the wiring harness.
2. Measure the resistance with a circuit tester between the glow
plug terminal and the engine body.
3. If the factory specification is not indicated, glow plug is faulty.
