INSPECTION PROCEDURE
HINT:

Read freeze frame data using the hand±held tester. Freeze frame records the engine conditions when
a malfunction is detected. When troubleshooting it is useful for determining whether the vehicle was
running or stopped. the engine was warmed up or not, the air±fuel ratio lean or rich, etc. at the time
of the malfunction.

READ VALUE ON HAND±HELD TESTER
(a) Connect the hand±held tester to the DLC3.
(b) Start the engine and push the hand±held tester tool main switch ON.
(c) When using hand±held tester, enter the following menu: ºDIAGNOSIS / ENHANCED OBD II / DATA
LIST / ALL / ENGINE SPDº.

The engine speed can be confirmed in DATA LIST using the hand±held tester. If there are no NE sig-
nals from the crankshaft position sensor despite the engine revolving, the engine speed will be indi-
cated as zero. If voltage output of the crankshaft position sensor is insufficient, the engine speed will
be indicated as lower RPM (than the actual RPM).
1 Check resistance of crankshaft position sensor.
PREPARATION:
Disconnect the C2 crankshaft position sensor connector.
CHECK:
Measure the resistance between terminals 1 and 2.

Reference: Inspection using the oscilloscope.
During cranking or idling, check the waveform between termi-
nals IG1 to IG8 and E1, and IGF1, IGF2 and E1 of the E6 and
E8 ECM connectors.
MONITOR DESCRIPTION
If the ECM does not receive the IGF after sending the IGT it interprets this as a fault in the igniter and sets
a DTC.
