Power Steering Light

[CTScott]

An OBD reader wouldn't help, as they can only read codes from the ECM, not from peripheral ECU's like the power steering ECU.

You can read the DTCs of the PS ECU by flashes of the PS light by doing the following:

1. With power off, connect terminals CG, TS and TC on the DLC3 connector (using jumpers).

2. Turn the ignition switch to the on position.

3. Read the number of times that the P/S warning light on the combination meter blinks.

• To indicate the normal code, the P/S warning light comes on for 0.25 seconds at intervals of 0.25 seconds (2Hz blink).

• When outputting a DTC, the P/S warning light displays it at intervals of 4 seconds. When outputting two or more DTCs, the P/S warning light displays each DTC at intervals of 2.5 seconds, and repeats from the first one 4 seconds after indicating the last one.

• If two or more malfunctions are detected at the same time, DTCs are displayed in ascending numerical order.
