1993 Suzuki Samurai JLFACTORY OEM SERVICE PROCEDURE
Samurai & Sidekick
- With ignition off, disconnect ECM connector. ECM is under lower left side of dash. Connect voltmeter between ground and terminal A13 (Samurai) or terminal B3 (Sidekick). See Fig 1 or Fig 2 .
- Remove distributor cap, rotor and shield cover. Turn ignition on. Check voltmeter reading when signal rotor is between magnet and Hall Effect pick-up coil. Voltmeter reading should be 3-5 volts.
- Turn signal rotor so that it is not between magnet and Hall Effect pick-up coil, thus breaking magnetic field. Voltage should be 0-1 volt. If results are not as indicated, inspect wiring and connections and repair as required. If wiring is okay, replace Hall Effect pick-up coil (crank angle sensor).
