ON–VEHICLE INSPECTION
NOTICE:

If the glow plug breaks, the ECU detects the breakage and stops the automatic operation, so
the burner heater does not activate. (For other failures, similarly activated.)

The cause of failures (such as voltage malfunction, overheating malfunction, short–circuit or
breakage of functional componects, etc.) and how to remedy are shown by connecting the DTC
tester and reading the DTC.
1. OPERATION
(a) Connect the DTC tester between the connector A (Vehicle harness) of DTC check harness and con-
nector B (Power heater harness).
(b) Start the engine.
(c) Pressing the DTC calling button displays a 3–digit number DTC.
