DTC P2008: Short Runner Solenoid Circuit: Testing
- Turn ignition on, engine not running. With the DRBIII®, read DTCs and record the related Freeze Frame data. Is the Good Trip counter displayed and equal to zero? If yes, go to next step. If no, go to step 8.
- Turn the ignition off. Disconnect the SRV Solenoid harness connector. Turn the ignition on. Using a 12-volt test light, connect one end to the ASD Relay Output circuit and the other end to the SRV Solenoid Control circuit at the SRV Solenoid harness connector. With the DRBIII®, actuate the SRV Solenoid. Does the 12-volt test light flash on and off? If yes, replace the SRV Solenoid. If no, go to next step.
- Ensure the MTV Solenoid is still actuated. Using a 12-volt test light connected to ground, probe the ASD Relay Output circuit in the SRV Solenoid harness connector. Does the test light illuminate brightly? If yes, go to next step. If no, repair the ASD Relay Output circuit.
- Turn the ignition off. Disconnect the PCM harness connectors. Measure the resistance between the SRV Solenoid Control circuit and ASD Relay Output circuit in the SRV Solenoid connector. Is the resistance below 5.0 ohms? If yes, repair the SRV Solenoid Control circuit for a short to the ASD Relay Output circuit. If no, go to next step.
- Measure the resistance between ground and the SRV Solenoid Control circuit at the SRV Solenoid harness connector. Is the resistance below 5.0 ohms? If yes, repair the short to ground in the SRV Solenoid Control circuit. If no, go to next step.
- Measure the resistance of the SRV Solenoid Control circuit from the SRV Solenoid harness connector to the appropriate terminal of the Miller Special Tool. Is the resistance below 5.0 ohms? If yes, go to next step. If no, repair the open in the SRV Solenoid Control circuit.
- There are no possible causes remaining, replace PCM. Program the new PCM. See PROGRAMMING .
- The conditions that set the DTC are not present at this time. The following may help in identifying the intermittent condition. With the engine running at normal operating temperature, monitor the DRBIII® parameters related to the DTC while wiggling the wiring harness. Look for parameter values to change and/or a DTC to set. Refer to any Technical Service Bulletins (TSB) that may apply. Visually inspect the related wire harness. Look for any chafed, pierced, pinched, or partially broken wires. Visually inspect the related wire harness connectors. Look for broken, bent, pushed out, or corroded terminals. Were any of the above conditions present? If yes, repair as necessary. If no, test is complete.
CAUTION:
Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal-to-pin connection. Use Miller Special Tool (8815) when performing diagnosis at PCM harness connectors.
NOTE:
Before continuing, check the PCM harness connectors for corrosion, damage or terminal push out. Repair as necessary.
WARNING:
When the engine is operating, do not stand in a direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing.
