DIAGNOSTICS ECD SYSTEM (1CD−FTV)(From September, 2003)
AVENSIS Supplement (RM1045E)
MONITOR DESCRIPTION
P 1238 (Injection malfunction, exclude open or short in injector circuit):
This DTC will be set if the engine speed fluctuation between each cylinder is large. The ECM monitors
changes in the crankshaft rotation speed using the crankshaft position sensor for detecting poor combus-
tion. Also, it identifies a faulty cylinder using the camshaft position sensor. The fluctuation counter incre-
ments when irregular crankshaft rotation speed variation exceeds the threshold at idling. Therefore, either
one of the cylinders has very poor combustion (Rough idle), the ECM sets this DTC.

Refer to DTC P0200 on page 05 −368.
INSPECTION PROCEDURE
HINT:
SIf DTCs other than P1238 are present simultaneously, first perform troubleshooting for them.
SRead freeze frame data using the hand −held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
1 CHECK OTHER DTC OUTPUT(IN ADDITION TO DTC P 1238)
(a) Connect the hand −held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand −held tester ON.
(c) Select the item ”DIAGNOSIS / OBD/MOBD / DTC INFO / CURRENT CODES”.
(d) Read DTCs. Result:

If any other codes besides P1238 are output, perform troubleshooting for those DTCs first.

MONITOR DESCRIPTION
When starting a cold engine, the ECM supplies current to the glow plug for a certain period of time. As supply-
ing the current to the glow plug is terminated, the large current is suddenly cut off, therefore the battery volt-
age then varies and also the output (duty ratio) from terminal M of the generator (alternator) varies. If these
variations are not occurred when the glow plug is turned from ON to OFF, or vice versa, the ECM judges the
current has not been supplied to the glow plug, and interprets this as open malfunction of the glow plug or
glow plug circuit.

DTC P0796 PRESSURE CONTROL SOLENOID ”C”
PERFORMANCE (SHIFT SOLENOID VALVE
SL3)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor to detect the actual gear position ( 1st, 2nd, 3rd, 4th
or 5th gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical
troubles of the shift solenoid valves and valve body.

when driving (2 −trip detection logic)
S Shift solenoid valve SL3 remains open or closed
S Valve body is blocked
S Shift solenoid valve SL3
S Automatic transaxle (clutch, brake or gear etc.)
S ECM
MONITOR DESCRIPTION
The ECM commands gear shifts by turning the shift solenoid valves ”ON/OFF”. According to the input shaft
revolution, intermediate (counter) shaft revolution and output shaft revolution, the ECM detects the actual
gear position ( 1st, 2nd, 3rd, 4th or 5th gear position). When the gear position commanded by the ECM and
the actual gear position are not same, the ECM illuminates the MIL and stores the DTC.
INSPECTION PROCEDURE
HINT:
Performing the ACTIVE TEST using the hand −held tester allows the relay, VSV, actuator and so on to oper-
ate without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one method
to shorten labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Turn the ignition switch off.
(b) Connect the hand −held tester to the DLC3.
(c) Turn the ignition switch to the ON position.
(d) Push the ”ON” button of the hand −held tester.
(e) Select the item ”DIAGNOSIS / OBD/MOBD / ACTIVE TEST / SHIFT”.
(f) According to the display on tester, perform the ”ACTIVE TEST”.
HINT:
While driving, the shift position can be forcibly changed with the hand −held tester.
Comparing the shift position commanded by the ACTIVE TEST with the actual shift position enables you
to confirm the problem (see page 05 −560).
