*NO RESPONSE FROM PCM (SCI ONLY) - JTEC (CONTINUED) 3. SCI CIRCUITS SHORTED TO VOLTAGE Turn the ignition on. Measure the voltage of the (D21) SCI Transmit (PCM) circuit. Measure the voltage of the (D20) SCI Receive (PCM) circuit. Is the voltage above 1.0 volt for either circuit? Yes >> Repair the SCI Circuit that measured above 1.0 volt for a short to voltage. Perform POWERTRAIN VERIFICATION TEST - VER 1. No >> Go To 4 4. (D21) SCI TRANSMIT (PCM) CIRCUIT OPEN Turn the ignition off. Measure the resistance of the (D21) SCI Transmit (PCM) circuit Is the resistance below 5.0 ohms? Yes >> Go To 5 No >> Repair the (D21) SCI Transmit (PCM) circuit for an open. Perform POWERTRAIN VERIFICATION TEST - VER 1. 8E - 64 ELECTRONIC CONTROL MODULES - ELECTRICAL DIAGNOSTICS DR/DH |
