  1. Check for proper input shaft (mainshaft) speed sensor installation.
  1. Turn the ignition switch to ON (II).
  1. Clear the DTC with the HDS.

Does the HDS indicate FAILED?
YES -
Go to Step 7 .

If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals between the input shaft (mainshaft) speed sensor and the PCM. If the HDS indicates NOT COMPLETED, go to Step 5 .
  1. Turn the ignition switch to LOCK (0).
  1. Jump the SCS line with the HDS.
  1. Disconnect PCM connector C (44P).
  1. Check for continuity between PCM connector terminal C40 and body ground, and between terminal C44 and body ground.
Is there continuity?
YES -
Go to Step 11 .
NO -
Repair open in the wires between PCM connector terminals C40, C44, and body ground (G101), or repair poor ground (G101), then go to Step 35 .
