Overview: ISO Code B193A - 11 Customer Symptom No indication on the P/R/N/D on state indicator. Fault Effects (On Vehicle) N/A Lamp Status (If Any) N/A. Fault Detection Condition No PWM dimming o/p to P/R/N/D module. Normal Operating Condition Cluster shall generate PWM o/p to control the dimming level of P/R/N/D module. Probable Trouble Area Related wiring Harness, connector or terminals damaged IPC connector wired wrong, Harness wire shorted, sensor connector wired wrong, sensor damaged Healing Condition IC shall generate PWM o/p to P/R/N/D module once short circuit is healed. Component Details: IC shall generate PWM o/p to P/R/N/D module as per below table. Preliminary Checks: 1. Check Battery Voltage is normal in the range (8v - 16v) 2. Check w/h for Pinch/Cut. 3. Check ECU & P/R/N/D module pins for oxidation, bending & damage. 4. Check and ensure IC is generating proper dimming o/p as per user select value. 5. Check Pin no. 29 (o/p) & 4 (GND) of the wired connector, whether it is according to the design specifications.
