1Check PSP Switch Signal Circuit.
When using SUZUKI scan tool:
1) Connect SUZUKI scan tool to DLC with ignition switch
OFF.
2) Start engine and select “DATA LIST” mode on scan tool.
3) Check power steering pressure switch. See Fig. 1.
Engine running and steering
wheel at straight-ahead position : OFF, 10 – 14 V
Engine running and steering
wheel turned to the right or
left as far as it stops : ON, 0 – 1 V
Is it in good condition?
When not using SUZUKI scan tool:
1) Turn ignition switch ON.
2) Check for voltage at terminal C01-5 of ECM
connector connected, under above each condition.
Is each voltage as specified?Signal circuit is in
good condition.Go to Step 2.
2Check Wire Harness.
1) Turn ignition switch OFF and disconnect PSP switch
connector.
2) Check for proper connection to PSP switch.
3) If OK, then check voltage at PSP switch wire terminal
with ignition switch ON. See Fig. 2.
Is it 10 – 14V?Power steering
