Test NS-6A: Repairing No Response Condition
NOTE:
Check for any codes that may be present before proceeding. See RETRIEVING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM. If no codes are present, continue with test.
- Check and verify Powertrain Control Module (PCM) connectors are securely connected. Attempt to start vehicle. If vehicle starts, go to TEST NS-6B: REPAIRING NO RESPONSE CONDITION . If vehicle does not start, disconnect Throttle Position (TP) sensor connector. Turn ignition on. Using a voltmeter, check voltage on TP sensor 5-volt supply circuit. See TP SENSOR CONNECTOR WIRE IDENTIFICATION table. If voltage is 6 volts or less, go to next step. If voltage is more than 6 volts, repair open grounds at Powertrain Control Module (PCM) connector terminals No. 10, 47 or 50. See PCM CONNECTOR WIRE IDENTIFICATION table. Perform TEST VER-1A: NO START VERIFICATION .
- Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Turn ignition on. Connect a 12-volt test light between fused ignition switch output circuit and ground at PCM connector. See PCM CONNECTOR WIRE IDENTIFICATION table. If test light is illuminated, go to next step. If test light is not illuminated, repair open fused ignition switch output circuit between PCM connector and ignition switch. Also check fuse. Perform TEST VER-1A: NO START VERIFICATION .
- If test light was bright, go to next step. If test light was not bright, repair high resistance in fused ignition switch output circuit. Perform TEST VER-1A: NO START VERIFICATION .
- Connect a 12-volt test light between fused B+ circuit and ground at PCM connector. See PCM CONNECTOR WIRE IDENTIFICATION table. If test light is illuminated, go to next step. If test light is not illuminated, repair open fused B+ circuit. Perform TEST VER-1A: NO START VERIFICATION .
- If test light was bright, perform TEST NS-6B: REPAIRING NO RESPONSE CONDITION . If test light was not bright, repair high resistance in fused B+ circuit. Perform TEST VER-1A: NO START VERIFICATION .
