NOTE: Do not replace the engine control module (ECM) until a through terminal check reveals there are no
short/open circuits.
NOTE: Check that the ECM ground circuit is normal before checking for the cause of the problem.
NOTE: After the ECM detects a malfunction, a diagnostic trouble code is recorded the next time the engine is
started and the same malfunction is re-detected. However, for items marked with a "*1", the diagnostic trou-
ble code is recorded on the first detection of the malfunction.
NOTE: The codes marked with a "*2" in the diagnosis code number column have the following two conditions
for recording the diagnostic trouble code.

• In case that the misfire causing the damaged catalyst is detected, the diagnostic trouble code is recorded

at the time.

• In case that the misfire deteriorating the exhaust gas is detected, the diagnostic trouble code is recorded

when the same malfunction is redetected after the next engine start.

SYMPTOM CHART

M1131151502658

WARNING

When touching the throttle valve, surely shut off the driving circuits of the throttle valve. In
the event that the throttle valve is operated, a finger might be injured as the result of being
caught by the throttle valve.

CAUTION

During diagnosis, a DTC associated with other systems may be set when the ignition switch is turned
on with connector(s) disconnected. On completion, confirm all systems for DTC(s). If DTC(s) are set,
erase them all.

CAUTION

Disconnecting the battery cables or removing the combination meter will erase the learned value of
the fuel gauge. To recover the learned value, input a vehicle speed (by actually driving the vehicle or
inputting a simulated vehicle speed), and stop the vehicle. This will complete the learning process.
NOTE: Check that the ECM ground circuit is normal before checking for the cause of the problem.
NOTE: When the racing (2,000 to 5,000 r/min or more) continues on the vehicle stopped with no load during
the specified time or more, the increase in the engine speed might be limited. This comes from the engine
protection and control functions and is not a malfunction.
