Lighting
The technician notices that the left turn signal flashes normal but the right turn signal flashes rapidly. This change in the circuit could cause the difference.
What is a change in circuit resistance in the right vs left sides of the circuit?
This device replaced the brush and slip ring in the steering column on vehicles with SRS systems.
What is the clockspring?
What is a dry reservoir? clogged hose? clogged nozzles? etc.
What is a horn that is grounded through the bracket or body of the horn to the chassis?
What is electromotive force?
This variable resistor allows for the dimming of the dash lights.
What is a rheostat?
Technician B says that this step in the replacement of the driver's airbag procedure is crucial to the safety of the technician.
What is disabling the SRS system?
(Kia wipers)
Wipers do not work in the high speed setting. the tech finds battery voltage at pin 2 BLK/ORG wire at the switch and finds 0 volts at pin 4 Red wire at the wiper motor.
This condition would cause those DMM readings.
What is an open in the wiring between the switch and the motor?
The horn circuit uses this to reduce the current required to control the circuit.
What is a relay?
The movement of free electrons in a conductor.
What is current or amperage?
This condition could cause the brake lights to flicker on and off when the vehicle travels over bumps in the road and the brake pedal is not depressed.
What is a miss-adjusted brake light switch?
Technician A says that this component must be replaced along with any deployed airbags.
What is the control module?
Tech A says to install the wiper arms and then cycle the new wiper motor on and off.
Tech B says to install the wiper arms after cycling the new wiper motor on and off.
Who's correct?
Who is technician B?
(2006 GMC sierra 6.0L Eng 1500)
These two components could cause the horns to sound non-stop.What are a stuck relay and a malfunctioning BCM?
The unit of measurement for the opposition of current flow in a circuit.
What are ohms?
(2009 ranger)
The high beam indicator doesn't light up when the high beams are selected. No other concerns are present. Which of the following is the cause?
Open circuit at S214
Bad bulb
Open circuit at G204
All of the above
None of the above
What is a bad bulb?
This is the name to describe the sensor that provides ground to the inflation circuit.
What is the discriminating sensor?
(2010 Kia)
The wipers don't work in low or interval settings. The tech finds voltage at pin 6 with the low/interval settings. She also finds ground at pin 5.
This detail in her diagnosis/customer concern eliminates the internal circuit breaker from the list of possible failed components.
What is nothing mentioned about the high speed setting being faulty. All the speeds get ground through the circuit breaker.
(GMC Horn Diagram)
While the horn doesn't work by pressing on the switch, it does work when pins 30 and 87 are jumped at the relay. Any of these components can be the cause, the multi-function switch, cancel cam, horn switch or this component.
What is a bad relay?
This type of circuit fault will activate the circuit protection device. (Be specific about the location of the fault)
(2009 ranger)
The flash to pass circuit works if the headlight switch is on or off because the circuit get power from this connection.
What is VBATT/fuse 11 10A?
These are the two common types of inflator systems used for airbag systems. In other words, the two types of mechanisms to inflate the airbags.
What are solid fuel and compressed gas?
(Kia wipers)
The wipers do not work in any setting. the 25A fuse is blown. the motor works as it should when bench tested. Which of the following is the cause?
An open in the ORG wire.
A short in the YEL wire.
A short to ground in the BLK/ORG wire.
An open in the GRN wire.
What is a short to ground in the BLK/ORG wire?
(GMC Horn diagram)
This condition would lead the technician to find voltage at pins B and A on both horns while pressing the horn switch on this GMC with a no sound from the horns concern.
What is a faulty ground?
The measurement of "live resistance" in a circuit.
What is voltage drop?
