Where is the AC switch on the back of a checker?
Where is the AC switch on the back of a checker?
According to the GM schematic from the dealer for a 98, this should be the High Pressure switch. This line is also switched with the AC button on the dash. Checker has two different Hi Pressure switches. One that would fit the back of the compressor and one that would fit the supply line on the system.
Where do I find the wiring connector on my computer?
Locate and release the wiring connector to gain access to the electrical pins which connect the system wiring into the computer. This will expose the connector pins which will be used for testing purposes.
How are the wires connected to the sensor?
This is a three wiring sensor, one wire is used for sensor power, the other two go directly into the computer for sensing purposes. Once system power is confirmed with the key on, the next step is to test the connection between the sensor and the computer which will find broken wires.
Where is the AC switch on the accumulator?
Switch on the accumulator: DK GRN & BLK/WHT. Switch on the high side line: DK BLU & BLK/WHT. Switch on the compressor: LT GRN & DK GRN/WHT. The LT GRN line on the switch on the compressor is switched with the AC button on the dash, confirmed.
How can I tell if my ABS sensor has failed?
To determine if a sensor has failed there are one of two methods that can be used. Connect a code tool to pin point the sensor, or check them manually. These sensors are subject to road conditions and vibrations which can cause them to short out and stop working.
How can I tell if my wheel sensor has failed?
Slowly spin the hub or axle which will produce the voltage, if no readings can be found the sensor has failed and replacement is required. This is a typical reading from a wheel sensor. Configuration of the sensor mounting is different for each manufacturer but follow the same operation.
What should the voltage be on a Class 2 serial pin?
With the Ignition on, the voltage on class 2 serial data pin should be 5V or fluctuating between 3.5V and 5.0V, If open, PCM cannot transmit data to the scan tool. Connect positive DMM lead to DLC Battery + terminal Connect negative DMM lead to battery ground terminal
Which is an example of an ABS sensor wiring diagram?
This is an example of an ABS sensor wiring diagram. Be observant when first driving the vehicle after testing the ABS system. Listen for abnormal noises or performance issues that could indicate a problem which will need further inspection.
