Is there continuity?
YES -Go to step 7.
NO -Repair an open in the wire between cable reel connector A (20P) terminal No. 9 and body ground (G502), or repair poor body ground (G502).
- Turn the ignition switch to ON (II).
- Measure the voltage between cable reel connector A (20P) terminals No. 6 and No. 9.

Is there battery voltage?
YES -Replace the cable reel (see CABLE REEL REPLACEMENT ).
NO -Go to step 9.
- Turn the ignition switch to LOCK (0).
- Jump the SCS line with the HDS.
- Disconnect PCM connector A (44P).

Is there continuity?
YES -Repair a short in the wire between PCM connector terminal A32 and the cable reel connector A (20P).
NO -Check for loose or poor connections at PCM connector terminal A32. If the connection is OK, substitute a known-good PCM (see SUBSTITUTING THE ECM/PCM ) and recheck.
