DTC P1421 COLD START CONTROL
Description INFOID:0000000004500297
ECM controls ignition timing and engine idle speed when engine is started with prewarming up condition.
This control promotes the activation of three way ca talyst by heating the catalyst and reduces emissions.
On Board Diagnosis Logic INFOID:0000000004500298
DTC Confirmation Procedure INFOID:0000000004500299
NOTE:
• If DTC Confirmation Procedure has been previously conduc ted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
• If DTC P1421 is displayed with other DTC, firs t perform the trouble diagnosis for other DTC.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11V at idle.
WITH CONSULT-III
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Select “DATA MONITOR” mode with CONSULT-III.
4. Check that the “COOLAN TE MP/S” indication is between 4°C (39 °F) and 36 °C (97 °F).
If “COOLAN TEMP/S” indication is within the specified value, go to the following step.
If “COOLAN TEMP/S” indication is out of the s pecified value, cool engine down or warm engine up and go
to step 1.
5. Start engine and let it idle for 5 minutes.
6. Check 1st trip DTC.
7. If 1st trip DTC is detected, go to EC-1421, " Diagnosis Procedure " .
Diagnosis Procedure INFOID:0000000004500300Idle Air Volume Learning " .
