DIGITAL TRANSMISSION RANGE SENSOR
| CAUTION | When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery. Before testing starter, ensure transmission is in Park or Neutral. |
- With the vehicle in NEUTRAL, position it on a hoist. Remove the battery and tray. Disconnect the TR sensor electrical connector. Loosen the TR sensor bolts.
- Make sure the transaxle is in the NEUTRAL position. Using the TR Sensor Alignment Gauge, (T97L-70010-A), align the TR sensor and tighten the bolts. Connect the electrical connector. Before installing the battery tray, check the vent tube hose for any obstructions, kinks, or incorrect routing position. Check the correct operation with parking brake control engaged. The engine should start only in PARK or NEUTRAL. Backup lamps should illuminate in the REVERSE position.
SYSTEM TESTS
| Symptom | Perform Test |
|---|
| Engine Does Not Crank Or Relay Clicks | A |
| Unusual Starter Noise | B |
| Engine Cranks Slowly | (1) |
| Starter Spins, But Engine does not Crank | (2) |
| Engine Cranks With Clutch Pedal Not Depressed | (3) |
| (1) Perform VOLTAGE DROP TEST under ON-VEHICLE TESTING. (2) Inspect starter motor mounting. Inspect flywheel ring gear and starter motor gear for damaged and missing teeth. Repair or replace components as necessary. (3) Replace clutch pedal position switch. |

STARTER RELAY
- Remove starter relay from battery junction box. Check relay continuity. Continuity should exist between relay terminals No. 85 and 86, and between relay terminals No. 30 and 87a. (Scheme 12) Continuity should not exist between relay terminals No. 30 and 87. If continuity is as specified, go to next step. If continuity is not as specified, replace relay.
- Disconnect the ohmmeter. Connect terminals No. 30 and 85 to a 12 volt DC power and terminal No. 86 to ground. Measure voltage between terminal No. 86 and 87. If voltage is 12 volts, continue the test. If not, replace the relay. Disconnect power from terminal No. 85 and measure voltage between terminal No. 87a and 86. If the voltage is 12 volts, the relay is okay. If not, replace the relay.

STARTER MOTOR
| WARNING | When repairing the starter motor or working underhood in the vicinity of the starter motor, note the heavy gauge input lead connected to the starter solenoid is hot at all times. Make sure the protective cap is installed over the terminal and is reinstalled after repairing. Failure to follow these instructions may result in personal injury. |
