Tech Feature: Subaru Service Essentials

My stint at being a service advisor for a number of dealer service departments over the years gave me a lot of experience in “bundling” services into a package. Having a service plan or “menu” built value for the customer. It also provided the service department with reliable income. Though there are good and bad points to service menus, the basic idea is a good one, and works well for any kind of automotive service or repair facility.

Diagnostic Dilemmas: When Over-Voltages Electrocute PCMs

During the past nine months, I’ve had three instances of powertrain control module (PCM) failures on Jeep Wrangler vehicles that were evidently caused by an over-voltage condition. The first case involved an owner who requested that a local shop replace the fuel pump because his 1998 Wrangler was slow-starting in the morning. The shop found the pump pressure was marginal and replaced the pump. Because the Jeep still had the problem, the owner complained about the fuel pump, first to the shop and then to the local jobber supplying the pump.

P0335 and/or P0340L: Lexus MIL On Due To Low Battery Voltage

Applicable vehicles: 1994 and later models (non-­hybrid and hybrid). Condition: Low battery voltage can contribute to a MIL On condition for P0335 (Crankshaft Position Sensor ­Circuit) and/or P0340 (Camshaft Position Sensor ­Circuit) due to inconsistent rotational speed of the ­engine’s crankshaft. Recommendations: • Review the vehicle’s freeze-frame data and verify if the battery voltage was
