Meters and Gauges Removal And Installation Steps
Adapter Removal:
ADAPTER REMOVAL
1. Remove the adapter lock.
2. Pull the speedometer cable slightly into the passenger compartment, and remove the rear side of the adapter from the cable.
3. After turning the adapter so that the notched section is aligned with the tab on the cable side, remove the adapter by sliding it backwards.
Speedometer Removal:
SPEEDOMETER REMOVAL
Tie a cord to the end of the speedometer cable that is in the passenger compartment. Then remove the grommet inside the engine compartment, and pull the cable into the engine compartment.
Reed Inspection:
REED SWITCH INSPECTION
Using a circuit tester, check that continuity and discontinuity alternates between terminals 1 and 2 four times at every rotation of the shaft of the speedometer cable connection.
FUEL GAUGE RESISTANCE AND ENGINE COOLANT TEMPERATURE GAUGE RESISTANCE
Fuel Gauge Resistance & Engine Coolant Temp. Gauge Resistance <Vehicle Without Tachometer>:
1. Remove the power supply tightening screw.
2. Use a circuit tester to measure the resistance value between the terminals.
CAUTION:
When inserting the testing probe into the power supply terminal, be careful not to touch the printed board.
