Mazda 6. Manual — part 28
F–48
ON-BOARD DIAGNOSTIC
Vehicle Speed Sensor (VSS)
VSS circuit malfunction (P0500) (MTX vehicles without ABS)
•
Vehicle speed signal does not input after the following conditions are met:
— Gear is in other than neutral position
— Load is above 40%
— Engine speed is 2,000 rpm or above
Idle Air Control (IAC) Valve
IAC system malfunction (P0505)
•
The PCM monitors idle speed. If idle speed is 1,800 rpm or below for 3 s during KOER self test, the PCM
determines that the IAC system has a malfunction.
IAC system RPM lower than expected (P0506)
•
Actual idle speed is lower than expected by 100 rpm for 14 s, when brake pedal is depressed (brake switch is
on) and steering wheel is held straight ahead (power steering pressure switch is off).
IAC system RPM higher than expected (P0507)
•
Actual idle speed is higher than expected by 200 rpm for 14 s, when brake pedal is depressed (brake switch is
on) and steering wheel is held straight ahead (power steering pressure switch is off).
IAC valve circuit malfunction (P0511)
•
If the PCM detects that the PCM terminal 4G voltage is above or below threshold when IAC control duty target
is within16—70%, the PCM determines that the IAC valve circuit has a malfunction.
Power Steering Pressure (PSP) Switch
PSP switch circuit malfunction (P0550)
•
The PCM monitors PSP switch signal at the PCM terminal 1Z. If input voltage is low (switch stays on) for 1
minute when the VSS is above 60 km/h {37.3 mph} and ECT is above 60
°
C {140
°
F}, the PCM determines
that the PSP switch circuit has a malfunction.
PCM Configuration
PCM programming error (P0602)
•
No configuration data in PCM.
Note
•
If “PCM CONFIGURATION” is successful, the PCM stored DTC P0602 and illuminates the MIL (System i
s normal) Clear the DTC P0602 using WDS or equivalent after “PCM CONFIGURATION”.
•
MIL goes off after three drive cycles with no failure (DTCs remain in PCM).
Control module vehicle options error (P0610)
•
PCM data configuration error.
Variable Intake-air System (VIS) Control Solenoid Valve
VIS control solenoid valve circuit low input (P0661)
•
The PCM monitors VIS control solenoid valve control signal at the PCM terminal 4R. If the PCM turns the VIS
control solenoid valve off but voltage at the PCM terminal 4R still remains low, the PCM determines that VIS
control solenoid valve circuit has a malfunction.
VIS control solenoid valve circuit high input (P0662)
•
The PCM monitors VIS control solenoid valve control signal at the PCM terminal 4R. If the PCM turns the VIS
control solenoid valve on but voltage at the PCM terminal 4R still remains high, the PCM determines that VIS
control solenoid valve circuit has a malfunction.
Brake Switch
Brake switch input malfunction (P0703)
•
The PCM monitors changes in input voltage from the brake switch. If the PCM does not detect the PCM
terminal 1K voltage changes while alternately accelerating and decelerating 8 times.
Clutch Switch
Clutch switch input malfunction (P0704)
•
The PCM monitors changes in input voltage from the clutch switch. If the PCM does not detect the PCM
terminal 1R voltage changes while running vehicle with vehicle speed above 0 km/h {0 mph} and below 30
km/h {19 mph} 8 times alternately, PCM determines that clutch switch circuit has a malfunction.
ON-BOARD DIAGNOSTIC
F–49
F
Neutral Switch
Neutral switch input malfunction (P0850)
•
The PCM monitors changes in input voltage from the neutral switch. If the PCM does not detect the PCM
terminal 1W voltage changes while running vehicle with vehicle speed above 30 km/h {19 mph} and the clutch
pedal is depressed and released 10 times repeatedly, PCM determines that neutral switch circuit has a
malfunction.
Variable Air Duct (VAD) Solenoid Valve
VAD control system circuit malfunction (P1410)
•
The PCM monitors the VAD solenoid control signal at PCM terminal 4C. If the PCM detects that the VAD
solenoid control signal does not change when VAD solenoid valve is switched to ON or OFF, the PCM
determines that VAD solenoid control circuit has a malfunction.
PCM
PCM +BB (back-up battery) voltage low (P1562)
•
The PCM monitors back up battery positive voltage at the PCM terminal 2Z. If the PCM detects battery positive
terminal voltage below 2.5V for 2 s, the PCM determines that the backup voltage circuit has malfunction.
Variable Tumble Control System
Variable tumble control system shutter valve stuck closed (P2006)
•
The PCM monitors mass air amount. If actual air flow amount is below estimated air flow amount when the
following monitoring conditions are met, the PCM determines that variable tumble control shutter valve has
been stuck closed.
— Engine speed is above 3,750 rpm
— Engine coolant temperature is above 63
°
C {145
°
F}
— Throttle valve opening angle is above threshold

: Maximum calculated load value varies depending on engine speed
Variable tumble control solenoid valve circuit low input (P2009)
•
The PCM monitors variable tumble control solenoid valve control signal at the PCM terminal 4T. If the PCM
turns the variable tumble control solenoid valve off but voltage at the PCM terminal 4T still remains low, the
PCM determines that variable tumble control solenoid valve circuit has a malfunction.
Variable tumble control solenoid valve circuit high input (P2010)
•
The PCM monitors variable tumble control solenoid valve control signal at the PCM terminal 4T. If the PCM
turns the variable tumble control solenoid valve on but voltage at the PCM terminal 4T still remains high, the
PCM determines that variable tumble control solenoid valve circuit has a malfunction.
BARO Sensor
BARO sensor circuit low input (P2228)
•
The PCM monitors input voltage from BARO sensor. If input voltage at the PCM terminal 1G is below 0.35 V,
the PCM determines that BARO sensor circuit has a malfunction.
BARO sensor circuit high input (P2229)
•
The PCM monitors input voltage from BARO sensor. If input voltage at the PCM terminal 1G is above 4.92 V,
the PCM determines that BARO sensor circuit has a malfunction.
Generator
Generator terminal B circuit open (P2502)
•
The PCM judges generator output voltage is above 17 V and battery positive voltage is below 11 V.
Generator output voltage signal no electricity (P2503)
•
The PCM needs above 20 A from the generator, and judges generator output voltage to be below 8.5 V during
engine running.
Battery overcharge (P2504)
•
The PCM judges generator output voltage is above 18.5 V or battery positive voltage is above 16 V during
engine running.
Controller Area Network (CAN)
Can bus off (U0073)
•
CAN controller is damaged.
PCM cannot receive any signals from ABS, ABS/TCS or DSC HU/CM control module (U0121)
•
PCM cannot receive any signals from ABS, ABS/TCS or DSC HU/CM control module.
F–50
ON-BOARD DIAGNOSTIC
PCM cannot receive any signals from instrument cluster (U0155)
•
PCM cannot receive any signals from the instrument cluster.
