Honda Element. Manual - part 85

 

 

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.

General Description 

The electronic throttle control system (ETCS) controls the throttle valve opening. The system is composed of 
the throttle actuator, the throttle valve, throttle position (TP) sensors A and B, the throttle actuator control 
module, and the throttle actuator control module relay in the throttle body. 

The accelerator pedal position (APP) sensor is operated via the throttle cable to determine the accelerator

opening value when the driver presses the accelerator pedal. The accelerator pedal opening value is converted to 
a signal in the APP sensor, transmitted to the engine control module (ECM)/powertrain control module (PCM), 
and then transmitted to the throttle actuator control module. 

The throttle actuator control module determines the throttle valve target position according to the signal 
received and operates the throttle actuator to move the throttle valve to the target position. The actual throttle 
valve position is determined by TP sensors A and B installed in the throttle body. 

The ECM/PCM detects the malfunction of the throttle actuator control module relay ON, and a DTC is stored if 
the serial signal from the throttle actuator control module is input for more than a set time after the throttle 
actuator control module relay is turned OFF and throttle actuator control module operation is stopped.

Conditions for illuminating the MIL 

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the 
ECM/PCM memory. 

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.

DTC P2610 (132): ADVANCED DIAGNOSTICS 

DTC P2610: ENGINE CONTROL MODULE (ECM)/POWERTRAIN CONTROL MODULE (PCM) 
IGNITION OFF INTERNAL TIMER PERFORMANCE PROBLEM 

Fig. 244: Engine Control Module/Powertrain Control Module Communication Diagram 

General Description 

The engine control module (ECM)/powertrain control module (PCM) has a built-in ignition off timer that 
measures the duration of time from ignition off to the next ignition on. The measured duration is used for 
evaporative emission (EVAP) leak detection and temperature assumption of the catalytic converter. 

The CPU in the ECM/PCM accesses the ignition off timer when reading the measured duration. When the 
access process fails, a malfunction is detected and a DTC is stored. When an abnormality is found in the read 
data, a malfunction is detected and a DTC is stored.
