Component Parts Basic Check (Cont'd)

Power Supply for Glow Control Unit

  1. 1
    Disconnect "S" terminal for starter motor to prevent engine from cranking.
  2. 2
    Disconnect glow control unit harness connector.
  3. 3
    Check terminal(s) 13 (Models with E.G.R.: 5, 6, 25 and 35 ) for ground continuity.
    Continuity should exist (0Ω).
    If N.G., check ground harness.
    Connector/terminal diagram labelled 'With E.G.R.' showing harness connectors with a resistance/continuity meter symbol (Ω) connected at two points. Top-left of the four stacked diagrams illustrating ground continuity check.

  4. 4
    Check voltage at each terminal according to the following chart.
    If N.G., check component parts and their related harness according to the following chart.
    Connector/terminal diagram labelled 'With E.G.R.' showing harness connectors with voltmeter (V) symbols connected at two points, illustrating voltage check at terminals.
