Test Kl: Shift Indicator Light: Testing

  1. 1) Check SIL Operation

    Inspect SIL while driving vehicle. SIL should turn on when optimum shift RPM for each gear is reached. SIL should turn off after shift is complete or while in top gear. If SIL is always illuminated, go to step  4). If SIL does not illuminate, go to next step.

  2. 2) Check METER Fuse (10-Amp)

    Remove METER fuse and inspect. If the fuse is okay, reinstall fuse and go to next step. If fuse is not okay, repair short circuit as necessary. Replace SIL circuit fuse.

  3. 3) Check SIL Bulb

    Remove SIL bulb and inspect. Using a DVOM, perform a continuity check if you suspect an open filament and cannot determine the bulb's condition visually. If the SIL bulb is okay, go to step  5). If the SIL bulb is not okay, replace SIL bulb.

  4. 4) Check SIL Circuit For Short To Ground In Harness

    Turn ignition switch to OFF position. Disconnect PCM. Using DVOM, measure resistance between the SIL circuit at PCM harness connector and the battery negative terminal. If resistance is greater than 10 k/ohms, replace PCM. If resistance is not greater than 10 k/ohms, repair short circuit.

  5. 5) Check IGN Start/Run Voltage To SIL Socket

    Turn ignition switch to OFF position. Remove SIL bulb. Turn ignition switch to ON position. Using a DVOM, measure voltage of the SIL circuit between the SIL socket and chassis ground. If the voltage greater than 10.5 volts, turn ignition switch to OFF position and go to step  8). If the voltage is 10.5 volts or less, repair open SIL circuit.
    NOTE: A break in step numbering sequence occurs at this point. Procedure skips from step 5) to step 8). No test procedures have been omitted.

  6. 8) Check SIL Circuit For Open In Harness

    Turn ignition switch to OFF position. Disconnect PCM. Using a DVOM, measure resistance between SIL circuit at PCM harness connector and SIL bulb socket. If resistance is less than 5 ohms, replace PCM. If resistance is 5 ohms or greater, repair open circuit.
