Code 15 - Ignition Output Signal

NOTE: If engine will not start, continue cranking for 20 seconds to reproduce trouble code.
  1. Turn ignition off. Remove appropriate fuse for 10 seconds to reset ECU. See CLEARING CODES  . Start engine. Verify if CHECK ENGINE light is on and if LED is flashing Code 15. If Code 15 is present, go to next step. If Code 15 is not present, problem is intermittent. Check connector at distributor and related circuits.
  2. Turn ignition off. Disconnect 6-wire connector at ignitor. Turn ignition on. Measure voltage between ground and Black/Yellow wire terminal on wire harness side. If battery voltage is not present, repair open Black/Yellow wire between connector and ignition switch.
  3. If battery voltage is present, turn ignition off. Reconnect 2-wire or 6-wire connector. Connect ECU Test Harness between ECU and ECU connector. See Figure and Figure . Turn ignition on. Individually measure voltage between negative terminal A26 (A18 on 2.0L) and positive terminals A21 and A22 (B15 and B17 on 2.0L). See Figure and Figure .
    NOTE: If wire between ignitor and ECU is shorted, ignitor may be damaged.
  4. On 2.1L, if approximately 10 volts is present, substitute a known good ECU, and retest. If condition is corrected, replace original ECU. If specified voltage is not present, check for short or open in White wire between distributor and ECU terminals A21 and A22. If wires are okay, replace ignitor unit.
  5. On 2.0L, if battery voltage is present, substitute a known good ECU, and retest. If condition is corrected, replace original ECU. If battery voltage is not present, turn ignition off.
  6. Disconnect 6-wire ignitor connector from ECU side only. Check for continuity between White wires and ECU terminals B15 and B17 and ignitor. If continuity does not exist, repair as necessary.
  7. If continuity exists, check for continuity between ground and White wires of 6-wire connector. If continuity exists, repair short to ground. If continuity does not exist, replace ignitor unit.
