MONITOR DESCRIPTION
The ECM continuously monitors its main CPU and monitor IC. This self-check ensures that the ECM is functioning properly. If outputs from main CPU and monitor IC are different and deviate from the standard, the ECM will illuminate the MIL and store this DTC.

HINT:
Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, 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.
PROCEDURE
1. |
CLEAR DTC |
(a) Clear the DTCs.
Powertrain > Engine > Clear DTCs(b) Turn the ignition switch off.
|
2. |
READ OUTPUT DTC (DTC P060647) |
(a) Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.
(b) Connect the cable to the negative (-) auxiliary battery terminal.
(c) Turn the ignition switch to ON.
(d) Wait 1 second or more.
(e) Read the DTCs.
