Current Data, Mode 1

Current data, mode 1

In Mode 1 the current diagnostic data can be interrogated. Additionally the readiness code can be displayed on the (PID1 display field 4).
Breakdown of parameter identification (PID): See diagnostic data chart listed below.
The On Board Diagnostic (OBD) program can be used to check whether individual parameters correspond to actual engine condition.

- Press -1- button to select mode 1 current data.

Display Will Appear As Shown
Mode 41 PID x Module 10*-->
Current data

Module 10* or 1A* will be displayed alternately when:
- Module 10 = Engine Control Module (ECM) -J220-, or
- Module 1A = Transmission Control Module (TCM) -J217- have the same parameter identifications.

Example: Engine Coolant Temperature is measured at the ECM and ATF at the TCM.

Diagnostic data must be individually interrogated via the H button. Press the Print button to obtain a printout.
- The MIL is said to be switched ON when the engine is not idling, and only the ignition is switched ON.

- Press -> button to display any additional diagnostic data.




PID 3: Fuel Injection System Status

When the 3rd position from the right is 1, the injection status is recognized as available.
- Press -> button.




PID4: Calculated load value %
Specification at idle: approx 2%

- Press -> button.




PID5: Engine Coolant Temperature °C

Indicates the current engine coolant temperature
Specification for engine at normal operating temperature: 80 to 105°C (176 to 221°F)
- Press -> button.




PID5: Coolant Temperature °C

Indicates the current ATF temperature
When the ATF specification is above 14O°C (284°F) with engine at normal operating temperature, 80°-105°C (176°-221°F) a DTC will be stored.
- Press -> button.




PID6: Short Term Fuel Trim, Bank 1 %

The oxygen sensor control integrator in % is displayed here.
- Press -> button.




PID7: Long Term Fuel Trim, Bank 1 %

The adaptation increases the value in % depending upon altitude.
- Press -> button.




PID12: Engine speed (RPM).

The engine speed (RPM) is displayed here.
- Press -> button.




PID12: ENgine Speed (RPM)

The input speed (RPM) from transmission is displayed here.
- Press -> button.




PID13: Vehicle speed (mph)

Current vehicle speed display
- Press -> button.




PID14: Ignition timing advance °.

Specification at idle: 12 fluctuating.

If the displayed ignition angle is constant and later than 12°, then the cause can be a faulty knock sensor.
- Press -> button.




PID15: Intake Air Temperature °C.

Measured at idle, slightly above ambient temperature
- Press -> button.




PID16: Mass Air Flow Rate, g/sec

Measured at idle approx.: 4.3 g/sec.

If the value is below 2.5 g/sec. unmetered (outside) air can be the cause.
- Press -> button.




PID17: THrottle Valve Position %

Specification at idle: 2-4%.

A too large or small a value leads to DTC: P1582
- Press -> button.




PID18: Secondary Air Injection Status.

When the 3rd position from right is 1, the secondary air injection system is recognized as available.
- Press -> button.




PID19: Oxygen Sensor Location

When the 1st and the 2nd position from right is 1, the heated oxygen sensors are recognized as available.
- Press -> button.




PID20: Heated Oxygen Sensor 1: 0.445 V X%

- The displayed value in volts must fluctuate between 0 and 1.0 volts.
- Press -> button.




PID21: Heated Oxygen Sensor 2: 0.445 V X%

- The displayed value in volts must fluctuate between 0 and 1.0 volt, however it must be at a slower rate than the HO2S (before three way catalytic converter).
- Press C button to exit mode 1.
