NOTE: Without a voltage signal return to the PCM, the Transmission Solenoid Power Control (TSPC) relay is commanded OFF. By using a fused jumper wire between a transmission solenoid control circuit and the signal return circuit, the TSPC relay circuit supplies power to the transmission solenoids when the ignition is cycled from OFF to ON. Do not use a solenoid control circuit that may be at fault.
NOTE: Read and record all DTCs.
A1 CHECK THE SOLENOID POWER CIRCUIT FOR VOLTAGE
Ignition OFF.
Disconnect: Transmission vehicle harness C1575
Inspect the connector for damaged or pushed out terminals, corrosion, loose wires and missing or damaged seals.
Using the chart, connect a fused jumper wire between one of the 7 solenoid control circuit pins on transmission vehicle harness C1575 and C1575-5 .
Ignition ON.
NOTE: Do not use a solenoid control circuit that may be at fault. Failure to jump pin 5 to a known good solenoid control circuit can cause incorrect diagnostic results.
