Block 14 Year 2 Gateway

A technician observes ignition coil current ramp time is 3.8ms on DSO. Spec is 2.0-3.0ms. This indicates:

• Normal operation

• Shorted windings

• Open circuit

• High resistance

During transmission pressure testing, line pressure is 20psi below spec in all gears. Likely cause:

• Clutch wear

• Valve body fault

• Torque converter

• Filter blockage

Parasitic draw test shows 1.25A after 20 minutes. Next diagnostic step:

• Replace battery

• Check alternator

• Pull fuses sequentially

• Verify key-off

ESC warning light illuminates during cornering. Live data shows yaw rate sensor:

• 0°/s when stationary

• Matches steering angle

• Stuck at max value

• Intermittent dropout

R1234yf recovery machine must use:

• R134a hoses

• Barrier hoses

• Steel fittings

• Universal couplers

Diagnostic report for P0302 should include:

• Compression test results

• Ignition waveform

• Freeze frame data

• Fuel trim values

CAN-H voltage measures 0.2V during communication. This suggests:

• Normal dominant state

• Short to ground

• Open circuit

• Termination fault

F-Gas documentation must be retained for:

• 1 year

• 3 years

• 5 years

• 10 years

Brake pedal pulsation during ABS activation is: (Block 11)

• Abnormal

• Requires fluid flush

• Expected operation

• Indicates air

EPB motor current >20A indicates: (Block 11)

• Normal operation

• Seized mechanism

• Low voltage

• Wiring short
