In this article, we will cover the replacement of the emergency oil pressure warning light sensor, the replacement of the parking brake warning light switch, the replacement of the brake light switch, the replacement of the reverse switch and the replacement of the fuel gauge sensor
In previous articles, we looked at how to replace the dashboard switches (article - Replacing the instrument panel and horn switches Gazelle Next) and the article - replacing engine control system sensors (article - Replacing Cummins ISF2.8 EMS sensors Gazelle Next)
Replacing the emergency pressure drop sensor
The sensor is screwed into the oil passage of the front cover of the cylinder block above the oil filter
Disconnect the negative battery terminal
Pry off with a screwdriver and move the bar of the wire block
Disconnect the wire block from the sensor by pressing the latch
Loosen the sensor
Unscrew it from the oil channel
Install the new sensor in reverse order.
Replacing the parking brake switch
Tools required: 11 wrench, Phillips screwdriver.
Raise the parking brake lever so that the stop moves away from the switch
We unscrew the screw securing the cover of the lever mechanism
Remove the cover
Disconnect the wire block from the output
Unscrew the switch from the bracket on the parking brake lever
Install the switch in reverse order.
Replacing the brake light switch
Check the brake light switch mounted on the brake pedal bracket. Press the brake pedal all the way.
When the switch stem is fully extended, the brake lights should be on, and when the stem is pushed in 4-5 mm (press with your finger), they should go out.
Otherwise, replace the switch.
Unscrew the bottom nut of the switch
Remove the switch
We press the latch and disconnect the block of wires from the switch
Install the switch in reverse order
We adjust the position of the switch using two nuts so that when the brake pedal is pressed, the brake lights light up, and when the pedal is released, they go out.
Reversing light switch replacement
The reverse light switch is screwed into the gearbox housing on the left side
Press the latch and disconnect the wire block from the switch
Weaken the switch with a 22 wrench
Unscrew the switch from the gearbox housing
To check the sensor, we connect a 12 V lamp and apply 12 volts.
The lamp should light up when you press the switch ball with your finger, while the ball stroke should be 1-2 mm.
Install the switch in the reverse order, rearranging the sealing ring.
Replacing the fuel level sensor
The fuel gauge sensor is part of the fuel pickup located in the fuel tank.
The sensor must be replaced if the fuel gauge in the instrument cluster changes its readings randomly for no apparent reason.
Disconnect the negative terminal from the battery
Remove the fuel intake (article - Repair of the GAZelle Next fuel intake)
We press the lock of the level sensor wire block
Disconnect the block from the connector
Press the two latches
Slide along the guide and remove the sensor
Install the fuel level sensor in reverse order.
