How is fault code P0658 fixed?

A typical diagnostic sequence used by mechanics, provided here for educational reference only. Diagnostic work should be performed by a qualified mechanic with the appropriate tools and training. 1. Read all stored codes and the freeze frame first. If you see transmission codes (P0700, P0750 family) sitting next to this one, that tells you which circuit and which actuator the module was worried about 2. Load-test the battery and check charging voltage at idle. A car sitting at 11 point something volts will throw all sorts of low-voltage codes, and there's no point chasing wiring until the supply itself is solid 3. Get a multimeter on the actuator supply terminals and check what's actually arriving, you want to see battery voltage, roughly 12 to 14V with the engine running. A reading well under that points straight at the wiring or a connection between the module and the actuator 4. Wiggle-test the connectors and harness while watching live data. A reading that jumps about when you move the loom has found your fault for you 5. Inspect fuses and any fusible link in that circuit, and pull the connectors apart to look for corrosion or pushed-back pins 6. If supply voltage is good all t

Can I keep driving?

Usually drivable, but get it diagnosed without delay.

What does it mean?

When I find a stored P0658 code, it means that the powertrain control module (PCM) has detected a low supply voltage condition in the circuit for a particular actuator. The actuator in question is typically associated with the automatic transmission, transfer case, or one of the differentials. Consult a professional technical data service to determine the actuator location and function as it relates to your vehicle.

Battery voltage is usually supplied to the actuator in question via a fused, switched circuit. The PCM sends a ground signal to the actuator in order to complete the circuit and accomplish a programmed function. When the actuator circuit is completed (as the PCM commands) it provides the PCM with an input voltage signal. If this input voltage signal is not received by the PCM, a P0658 will be stored and a malfunction indicator lamp (MIL) may be illuminated.

Some vehicles will require multiple drive cycles (with a failure) for a MIL to be illuminated.
