DTC P0607: Control Module Performance
- OUTLINE OF DIAGNOSIS
Judge NG when either the following is completed.
- When the read value of throttle position sensor 1 signal is mismatched between main CPU and sub CPU.
- When the read value of accelerator position sensor 1 signal is mismatched between main CPU and sub CPU.
- When the sub CPU operates abnormally.
- When the communication between mina CPU and sub CPU is abnormal.
- When the input amplifier circuit of throttle position sensor 1 is abnormal.
- When the cruise control cannot be canceled correctly.
- When the signal of brake SW1 and 2 is mismatched.
- When the directed angle from main CPU is abnormal.

Secondary Parameters Enable Conditions (1) Ignition switch ON (2) Ignition switch ON (3) None - (4) None - (5) Throttle opening angle (6) Brake SW (with cruise control) ON (7) None - (8) Cruise control OFF - GENERAL DRIVING CYCLE
- (1) - (4): Always perform the diagnosis continuously.
- (5): Always perform the diagnosis continuously on idling.
- (6): Perform the diagnosis when the brake pedal is depressed.
- (7): Always perform the diagnosis continuously.
- (8): Always perform the diagnosis continuously when the cruise control pedal is not operating.
- DIAGNOSTIC METHOD
Judge OK and clear NG when the malfunction criteria below are completed.
Judgment Value
JUDGMENT VALUE CHARTMalfunction Criteria Threshold Value - Difference of CPU on reading value of throttle position sensor signal
- Difference of CPU on reading value of accelerator position sensor signal
- WD pulse from sub CPU
- Communication between CPU
- Difference of signal on connection of amplifier
- Cruise control cancel signal at brake ON
- Brake switch 1, 2 signal
- Throttle opening angle directing value
Within 0.12 V
Within 0.07 V
WD pulse occur
Possible to communicate
Within x 4+/-0.6 V
Cruise control cancel signal ON
SW 1 and 2 are matched

Malfunction Indicator Light Illumination: Illuminates as soon as malfunction occurs.
- DTC CLEAR CONDITION
- When the OK idling cycle was completed 40 times in a row
- When "Clear Memory" was performed
- MALFUNCTION INDICATOR LIGHT CLEAR CONDITION
- When the OK driving cycle was completed 3 times in a row
- When "Clear Memory" was performed
- FAIL SAFE
Stop the current to electric control throttle motor. (Fix the throttle opening angle to 6°.)
- ECM OPERATION AT DTC SETTING
Memorize the freeze frame data. (For test mode $02)
