Component Testing

PNP Switch (M30 4L60E, M70 4L70E)

  1. Ignition OFF, disconnect the harness connector at the PNP switch.
  2. With the PNP switch in the following positions, test for infinite resistance between the ground terminal 7 and the signal terminal 3.
    • R
    • OD
    • D
    • 2
    • 1
    • If not the specified value, replace the PNP switch.
  3. With the PNP switch in the following positions, test for less than 2.0 ohms between the ground terminal 7 and the signal terminal 3.
    • P
    • N
    • If greater than the specified range, replace the PNP switch.

STRTR Relay

  1. Ignition OFF, disconnect the STRTR relay.
  2. Test for 60-180 ohms between terminals 85 and 86.
    • If not within the specified range, replace the relay.
  3. Test for infinite resistance between the following terminals:
    • 30 and 86
    • 30 and 87
    • 30 and 85
    • 85 and 87
    • If not the specified value, replace the relay.
  4. Install a 20 amp fused jumper wire between relay terminal 85 and 12 volts. Install a jumper wire between relay terminal 86 and ground. Test for less than 2.0 ohms between terminals 30 and 87.
    • If greater than specified range, replace the relay.
