DIAGNOSTIC PROCEDURE 1
Check ?B? Terminal Circuit
1. CHECK POWER SUPPLY FOR STARTER MOTOR ?B? TERMINAL
1. Remove fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
3. Turn ignition switch OFF.
4. Make sure that the starter motor ?B? terminal E203 terminal 2 (B/GY) connection is clean and tight.
5. Check voltage between starter motor ?B? terminal E203 terminal
2 (B/GY) and ground.
OK or NG
OK >> GO TO 2.
NG >> Check harness between the battery and the starter
motor for open circuit.
2. CHECK BATTERY CABLE CONNECTION STATUS (VOLTAGE DROP TEST)
1. Shift A/T selector lever to ?P? or ?N? position. (A/T models)
Keep depressing clutch pedal fully. (M/T models)
2. Check voltage between starter motor ?B? terminal E203 terminal
2 (B/GY) and battery positive terminal.
OK or NG
OK >> GO TO 3.
NG >> Check harness between the battery and the starter
motor for poor continuity.
3. CHECK STARTER MOTOR GROUND CIRCUIT (VOLTAGE DROP TEST)
1. Shift A/T selector lever to ?P? or ?N? position. (A/T models)
Keep depressing clutch pedal fully. (M/T models)
2. Check voltage between starter motor case and battery negative
terminal.
OK or NG
OK >> Starter motor ?B? terminal circuit is OK. Further inspec-
tion necessary. Refer to SC-16, "
WORK FLOW" .
NG >> Check the starter motor case and ground for poor continuity.
