

Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

Diagnosis Details

Conditions for illuminating the MIL

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the ECM/PCM
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the
freeze frame data are stored.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool Clear
command or by disconnecting the battery.

Fig. 251: Communication Diagram Between ECM/PCM And Control Module

General Description

The controller area network (CAN) transmits/receives pulsing signals to/from the control modules
simultaneously by using two signal lines (CANH and CANL).

When the engine control module (ECM)/powertrain control module (PCM) does not receive the signals via the
CAN lines for more than a set time, the ECM/PCM detects a malfunction and a DTC is stored.
