Circuit Test B10 - Neutral Gear Switch & Clutch Engage Switch

Fig 1: NGS & CES Circuits

NOTE: Enter this test only when directed here from SWITCH MONITOR TEST procedure. To prevent replacement of good components, be aware that the following non-EEC items may be at fault: clutch switch adjustment, clutch pedal operation, transaxle operation and neutral switch installation. This test is intended to diagnose only the following: clutch or neutral switch, and wiring harness.

1. Checking System Integrity  - Visually check all wiring, harnesses, connectors and components for evidence of damage, overheating, shorting or looseness. If a fault is found, repair as necessary. If no faults are found, go to next step.
2. Checking For Open Circuits  - Install breakout box and leave ECA disconnected. Set VOM on 200-ohm scale. Using CIRCUIT RESISTANCE  table, measure and record resistance between test pins No. 2 and 20 (ground). If all resistances are to specifications, go to step 5). If not, go to next step.
   CIRCUIT RESISTANCE
   
   

   Test Procedure	Ohms
   Clutch released and in gear	Less than 5
   Clutch depressed and in gear	Greater than 10k
   Clutch released and in Neutral	Greater than 10k
   Clutch depressed and in Neutral	Greater than 10k

3. Checking CES Operation  - Disconnect 2-pin CES connector. Set VOM on 200-ohm scale. Measure resistance between terminals on clutch engage switch with pedal depressed and released. If resistance is greater than 5 ohms with pedal depressed and less than 5 ohms with pedal released, go to next step. If switch does not meet specifications, adjust or replace as necessary.
