INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand-held tester or the OBD II scan tool. Freeze frame data records the
engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help deter-
mine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was lean
or rich, as well as other data from the time when a malfunction occurred.

1 Are there any other codes (besides DTC P2119) being output?
PREPARATION:
(a) Connect the hand-held tester or the OBD II scan tool to the DLC3.
(b) Turn the ignition switch ON and push the hand-held tester or OBD II scan tool main switch ON.
(c) When using hand-held tester, enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC
INFO / CURRENT CODES.
CHECK:
Read the DTC using the hand-held tester or the OBD II scan tool.
RESULT:
Display (DTC Output)Proceed to
P2119A
ºP2119º and other DTCB
HINT:
If any other codes besides P2119 are output, perform the troubleshooting for those DTCs first.

sensor data.
PREPARATION:
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch ON and push the hand-held tes-
ter main switch ON.
(c) Enter the following menus: DIAGNOSIS / ENHANCED
OBD II / DATA LIST / ETCS / ACCEL POS #1 and ACCEL
POS #2.

Cranking Hold Function Circuit
CIRCUIT DESCRIPTION
The starter is controlled by the ECM, when the ECM detects a start signal (STSW) from the ignition switch,
this system monitors the engine speed (NE) and continues to operate the starter until it has determined that
the engine has started (engine speed reaches approximately 500 rpm). If the engine is already running and
the ignition switch is turned to START, the ECM will not operate the starter.
WIRING DIAGRAM
Refer to DTC P0617 on page DI-296.
INSPECTION PROCEDURE
Hand-held tester:
1 Check operation of engine cranking.
CHECK:
When turning the ignition switch to the START position, check whether the starter motor starts.
OK:
Starter motor starts.
OK Check for intermittent problems (See page
DI-3).
