ON-BOARD DIAGNOSTIC [LF]

P0500 VSS circuit problem

With ABS/DSC

• If an error in the wheel speed signal from the ABS/DSC HU/CM is detected by CAN when the following

conditions are met:

— Neutral switch and clutch pedal position switch are OFF

— Load is above 40 %

— Engine speed is 2,000 rpm or above

— Brake switch is OFF

— Shift lever position (P, N, R position) (AT)

MT without ABS/DSC

• Vehicle speed signal from vehicle speed sensor is below 3.7 km/h {2.3 mph} when the following conditions

are met:

— Neutral switch and clutch pedal position switch are OFF

— Load is above 40 %

— Engine speed is 2,000 rpm or above

— Brake switch is OFF

P0505 Idle speed control system problem

• The PCM cannot control idle speed toward target idle speed while KOER self test.

P0506 Idle speed control system RPM lower than expected

• 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 (PSP) switch is off).

P0507 Idle speed control system RPM higher than expected

• Actual idle speed is higher than expected by 200 rpm for 14 s, when the brake pedal is depressed (brake

switch is on) and steering wheel is held straight ahead (power steering pressure (PSP) switch is off).

P050A Cold start idle air control system performance

• Actual idle speed is lower than expected by 100 rpm for 8.4 s when the target idle speed correction value for

cold start is above 0 rpm or ignition retard value is above 10 ° CA.

Note

• If atmospheric pressure is less than 72.3 kPa {542 mmHg, 21.3 inHg} or intake air temperature is below

-10 °C {14 °F}, the PCM cancels diagnosis of P050A.

P050B Cold start ignition timing performance

• The PCM monitors actual ignition timing using the CKP sensor while electronic spark advance control fast idle

correction operating. If the ignition timing is out of specified range, the PCM determines that the ignition timing

at cold condition has performance problem.

P0550 PSP switch circuit malfunction

• The PCM monitors PSP switch signal at PCM terminal 2T. If input voltage is low voltage (switch stays on) for 1

min. when the VSS is above 60.0 km/h {37.4 mph} and ECT is above 60 °C {140 °F}, the PCM determines

that PSP switch circuit has malfunction.

P0564 Cruise control switch circuit malfunction

• The PCM monitors the cruise control switch signal at PCM terminal 1AQ. If the PCM detects that any one of

following switches (ON OFF, SET/-, SET/COAST, RES/+) remains on for 2 min, the PCM determines that the

cruise control switch circuit has a malfunction.

P0571 Brake switch circuit problem

• The PCM monitors changes in input voltage for brake switch No.1 and No.2. If the PCM detects that both brake

switches No.1 and No.2 remain on or off for 15 s, it determines that the brake switch circuit has a malfunction.

P0601 PCM memory check sum error

• PCM internal memory check sum error

P0602 PCM programming error

• No configuration data in the PCM

P0604 PCM random access memory (RAM) error

• PCM internal RAM malfunction.

P0606 PCM processor

• The PCM internal CPU malfunction

P0610 PCM vehicle options error

• PCM data configuration error

P0638 Throttle actuator control circuit range/performance problem

• The PCM compares the actual TP with the target TP when the engine is running. If the difference is more than

the specification, the PCM determines that there is a throttle actuator control circuit range/performance

problem.
